Measuring Up

 
New dye lab equipment shortens testing times, ensures more precise measurements for improved
quality control.
As business conditions for the U.S. textile industry become more and more
competitive, the stresses on the industry’s manufacturing processes and methodologies become
correspondingly more demanding.

New dye lab equipment shortens testing times, ensures more precise measurement for improved
quality control.Today’s environment places a premium not just on price and quality, but on delivery
as well. Quick response is becoming the norm for those companies that want to grow or maintain
market share – and many U.S. textile companies are finding that their blue-chip customers will
accept nothing less. As a result, equipment and machinery manufacturers that supply the industry
are looking for innovative new ways to both cut production and testing time and ensure the
elimination of as much off-quality product as possible. Perhaps nowhere in the industry is that
more evident today than in testing and measurement equipment made for the dye lab.The modern dye
lab must be a sophisticated, scientific operation geared toward creating unparalleled consistency
and quality. From the manner in which shrinkage and elongation are measured, to the tolerance
specifications for color matches, there is little room for error. It is a well-known, if not
acknowledged, fact that inventory garners close scrutiny during lean economic times. Even the
suggestion or perception of variance from standards can send a perfectly good lot of yarn or fabric
back to the manufacturer as rejects.Therefore, one is more likely today to see rigorous testing
methods that drastically reduce both sampling and production time and labor; sophisticated
color-measurement devices that enable more exacting color matching; and state-of-the-art software
that does everything from evaluating samples, to monitoring production, to managing post-production
inspection and analysis.”Reducing testing time, eliminating redundancy and creating less
opportunity for off-quality goods – all of these factors can contribute significantly to the bottom
line of the manufacturers who are our customers,” said J. Mark Raiteri, president and CEO, Raitech
Inc., the Charlotte, N.C., manufacturer of textile control and measurement systems. “Our mission at
Raitech has been to provide these customers with relatively inexpensive equipment that creates the
opportunity for a rapid return on investment.” Shrinkage TestsAmong the company’s flagship products
is its Quickwash Plusª system. Originally developed in 1997 by Raitech and Cotton Incorporated,
Cary, N.C., an enhanced version, model EC300, was made available last year. Essentially, the
Quickwash Plus system radically reduces the time it takes to test for dimensional stability and
other fabric properties that require a washing and drying process. “The system reduces shrinkage
testing to about 15 minutes for most fabrics instead of up to 8 hours,” Raiteri said. “The
Quickwash Plus system uses a patented method for inducing the relaxation and shrinkage behavior of
textile fabrics. The process is one where a sample or samples are separately submitted to a short,
but complete, washing cycle in a whirling, oscillating hot-water bath followed by short rinse
cycles. Afterwards, the samples are subjected to a very short hydroextraction cycle and then
submitted to drying in a hot air stream. This method of drying induces constant motion of the yarns
at crossover points and flexing of the yarns in the fabric structure.” The Quickwash Plus system is
composed of a perforated vertical drum that contains up to five radially arranged partitions that
divide the space into an equal number of chambers capable of bi-directional rotation, he said. The
drum is enclosed in a thermally insulated protective casing covered by a lid and connected
mechanically to a shaft that can provide alternately a rotational or oscillating motion. The drum
has connections to a pressure air inlet from an air heater, a common water inlet for regulated
heated water and a water outlet for drainage. In addition to shrinkage, the Quickwash Plus system
can be used to evaluate a fabric’s tendency to spiral, twist or change in appearance. As well,
Raiteri said, it can be useful in reducing both time and effort in the determination of
colorfastness.”The overall benefit of the product is, of course, that it reduces the time it takes
to ensure the production of a quality product,” Raiteri said. “But also important is the fact that
the time and fabric savings alone can pay for the product in six months or less. The system only
uses one-fifth the fabric other testing methods require.”More than 300 Quickwash Plus units have
been sold, 100 of which have been to U.S. companies. “Currently, there is at least one Quickwash
Plus system in every country in the Americas,” Raiteri said. Customers include Cotton Incorporated,
National Textiles, Russell Athletics, Cone Mills, GaleyandLord, Guilford Mills and others, he
said.The latest offering from Raitech is a product called Quickviewª, an optical measurement device
for fabric shrinkage. “Quickview will do in a minute what it takes 15-30 minutes to do by hand,”
Raiteri said. “It eliminates up to 18 separate hand measurements.”Raitech also has available its
Quickcircleª fabric sample cutter; Quickcutª fabric cutter; Quickdryª fabric sample dryers; and
Quicktempª water temperature controller system. Testing ColorfastnessWhile the primary mission of
the Quickwash Plus system is to test for fabric shrinkage, United Kingdom-based James H. Heal –
represented in the United States by Advanced Testing Instruments Corp. (ATI), Greer, S.C. – focuses
on colorfastness with its Gyrowash machine. The latest incarnations of the Gyrowash range of
machines are used to investigate the fastness to washing, dry cleaning and chlorinated water of
colored textiles and leather.

Steven Webb, National Textile, checks color and quality of fabric prior to cutting with
ColorTools¨ software from Datacolor.Softrol, Acworth, Ga., manufactures a catalyst system,
ChemPulse, that includes a redundancy feature that continues chemical delivery to all washers when
one unit is taken out of service for maintenance or repair. Each catalyst, according the company,
can work in a preferred network range of machines to ensure equal utilization of
equipment.SpectrophotometersSpectrophotometers measure light reflected from an object at each
wavelength in the color spectrum. New developments in this arena include the LCS+ Liquid Color
Spectrophotometer from Mahlo America Inc., Spartanburg, S.C., and the CM-2600d portable from
Minolta, Japan.The LCS+ is a highly precise transmission spectrophotometer that spectrally measures
the color of transparent liquids, according to Udo Skarke, executive vice president, Mahlo America
Inc. “It makes sure the pigment in the dyes is the same,” he said. The LCS+ is designed for use
with disposable plastic cells, high-precision optical cuvettes or 11-millimeter (mm) tube cells.The
CM-2600d from Minolta is the first portable spectrophotometer on the market with instantaneous
ultraviolet (UV) adjustment, according to Norm Demers, technical support manager for Minolta’s
Light and Color Applications Center Instrument Systems Division.The product is lightweight and
compact and features dual apertures of 3 mm and 8 mm, Demers said. The CM-2600d performs like a
bench-top spectrophotometer and is suited for measuring fluorescents, paper, textiles or any
product with optical brighteners. Also from Minolta is the CM-3600d benchtop spectrophotometer for
reflectance and transmittance color measurement. This product, according to Demers, performs faster
and more accurate measurements of samples with gloss differences and offers instantaneous numerical
UV adjustment for samples that contain a UV-absorbing light component, such as fluorescing dyes,
pigments and optical brighteners.As well, Minolta offers the CL-200 Light Source Chroma Measurement
System, which can perform measurements of tristimulus colorimetrics, chromaticity, color
difference, correlated color temperature and illuminance of light sources. The CL-200 System
features an expandable modular design that uses compact and lightweight interchangeable components,
according to Demers. The system can be used for such applications as research and development of
light sources; color adjustment of cathode ray tubes (CRTs); flat panel displays and other display
devices; color evaluation and control of light boxes and booths; and optimum installation of
projection systems and presentation lighting.An ongoing argument for some concerns exactly when a
fabric should be tested for color consistency and quality. Should the greige fabric be tested for
consistency and dyeability before production is finished – or should the final product be tested to
measure conformity to specifications Mahlo’s Skarke told Textile Industries that U.S. manufacturers
in general produce dyed fabric and then use off-line testing as a quality control feature. “What we
are finding, however, is that a number of European companies are beginning to test fabric in-line
in order to be able to make quality decisions on the production floor. To this end, Mahlo has
developed its Colorscan CIS-10 offering, an on-line sensor that runs back and forth across the
fabric during production. The CIS-10 logs any variations in shade, both across and along the length
of the fabric.”The CIS-10 can measure properties on-line and at high speed after mercerizing, after
the range, at just about any step in the process, and can cull bad greige goods. That way, the
textile manufacturer knows very quickly that the products being manufactured are top quality. This
is faster, provides less waste and increases efficiency,” said Skarke.Testing Light Stability And
WeatheringOf course, color consistency, colorfastness and dimensional stability are not the only
factors that determine the quality and marketability of a particular yarn or fabric. Resistance to
the deteriorating effects of sunlight and other harsh lighting systems, for example, is critical to
the performance of many products today, particularly activewear. The Q-Sun Xenon Test Chamber,
manufactured by Q-Panel Lab Products, Cleveland, uses full-spectrum xenon arc lamps to reproduce
the damaging wavelengths of light encountered in a multitude of environments, according to Ronald
L. Roberts, U.S. sales manager. The Q-Sun can be used to simulate and accelerate these conditions
for both research and development and quality-control applications. The Q-Sun is used for the
selection of new materials, the improvement of existing materials or the evaluation of how changes
in formulations affect product durability. In addition to photodegradation, Roberts said, the Q-Sun
can also be operated as a weathering tester.From SDL America Inc., Charlotte, N.C., the M237 Light
Fastness Tester determines colorfastness and sunlight degradation through the use of a 500-watt
mercury-blended tungsten lamp. The machine includes a presettable timer and time-elapsed counter.
The SDL M237 can be fitted with type C, D or E sample holders within which humidity can be
controlled using saturated salts. The company also has available a rapid fade model fitted with a
400-watt mercury tungsten high-powered lamp.Software For Control, EfficiencyNot all of the
improvements in quality measurement and production efficiency are related to manufacturing
equipment. A number of software offerings are on the market that assist companies in formulation
and dispersement of dyes and chemicals, as well as product testing and sorting.SheLyn Inc.,
Greensboro, N.C., has its SLI-Form¨ package that can interface with a wide variety of
spectrophotometers. In addition to formulation, SLI-Form can evaluate dyeings to ensure accuracy in
formulations and can correct or fine-tune formulas in production, according to Ann C. Laidlaw,
manager, color applications.DCIMatch from Datacolor International, Lawrenceville, N.J., provides
for the matching of any shade on any substrate or blend. DCIMatch features the company’s Smart
Match¨ Expert System, which “learns” the behavior of dyestuffs, processes and substrates in order
to match color theory to real world practices.GretagMacbeth, New Windsor, N.Y., offers its
ProPalette Textile Formulation software, a complete quality control program that measures color
difference, plots variations in color and features pass/fail tolerancing for all major color spaces
and illuminants. As well, ProPalette offers dyestuff calibration and performance
monitoring.National Textiles – Committed to CustomersIf there is one thing management at the
National Textiles LLC plant in Forest City, N.C., has learned in an era of extreme competitive
pressure, it’s that quality is a process-by-process measurement.”Today, we’re driving quality into
the process, instead of waiting until the end,” said Bonnie Davis, the plant’s quality manager.
“Two years ago, we would do quality audits on the finished product. Now more than 90 percent of our
quality is checked in process from the very beginning.”

Plant Manager Ken Warren and Quality Manager Bonnie Davis inspect dyed knits at National
Textiles’ Forest City TextilesAs a result, the plant has reduced its lead time and increased
production efficiency – while continuing to manufacture highly respected dyed knit fabrics.National
Textiles is a vertically integrated company, encompassing everything from yarn to cut fabrics. At
the Forest City Plant, yarn is brought in from sister facilities, knitted, dyed and finished. The
plant ships about 1.3 million pounds of finished fabric per year and cuts about 200,000 dozen
samples per week.Like many other companies in the U.S. textile industry, National Textiles feels
the mounting pressure from the expanding influx of low-cost foreign textiles, particularly from the
Far East. The company, however, is committed to a strategy it believes will keep National
competitive through the rollback of quotas in 2005 and beyond.”We key in on things that are really
important to our customers,” Davis said. “We identify those things they are really looking for and
focus on them.”That commitment runs through the company, from top to bottom, Plant Manager Ken
Warren said. “Our basic philosophy is simple. We give our customers what they want when they want
it. We’re working with lead times we wouldn’t even have thought about a few years ago. The
commitment runs not only to processes but also to equipment purchases. National’s Forest City Plant
was among the first facilities, for example, to embrace the Quickwash Plus system offered by
Raitech Inc. Armed with the potential of saving time and simultaneously increasing quality, Warren
saw the opportunity to serve both his customers and the company.”The Quickwash Plus machine has
really taken our fabric performance to a new level. It gives us a much quicker view of what the
fabric will be like after the compaction process,” Warren said.”To meet our objectives today, we
can’t hold up a product for a lab test that might take six hours or more before we can begin
cutting fabric,” Davis said.National uses other state-of-the-art systems, such as ColorTools¨
software by Datacolor International, to ensure dyed fabric is within customer specifications. The
company has a reputation of being among the lowest-cost manufacturers of knitted fabrics in the
United States. But that is only part of the reason behind the company success, according to
Davis.”People usually come to us because of price,” she said. “But they stay because of the quality
and service they receive.”Today, our focus, instead of on mass production, is on the individual
lots that we ship to our customers. On-time performance is measured on a weekly basis. Our quality
process has enabled us to move product through the plant without getting stopped along the way.
And, if for any reason the flow does stop, we know how to address and correct the situation
quickly.”In an era in which competition has made quick response the norm, on-time performance is
especially critical if a company is to keep its customers. “If a product doesn’t ship within our
specified lead time, it’s late,” Warren said. “And being late gets a lot of attention around here.
But we believe that – if we continue to deliver a high-quality product that exactly meets our
customers’ wants and needs and deliver it on time – then we will continue to grow. I truly believe
that if you focus on service and quality, you will not lose customers.”Prospects for continued
success for National are good, Warren said. The company is comfortable without being complacent.
Indeed, there are many challenges looming on the horizon, but both Warren and Davis believe
National’s commitment to customer service will be more than enough to keep the company at the top
of supplier lists for many of its customers.

Build A Winning Culture

While the textile industry has been going through tough times recently, cycles of good and
bad times are not unique to the industry. Over the long run, every industry has its ups and downs.
So, when tough times hit, why do some firms weather the storm and come out stronger, while others
are casualties At least part of the answer to this critical question has become more evident over
the last two decades. The “secret” to success in good and bad times, across a wide range of
industries, lies in large measure in having a strong corporate culture that ensures the flow of
ever-higher-quality products and services.Defining Corporate CultureWhat is corporate culture Many
different definitions of corporate culture have been offered over the years. At the heart of all
these definitions, however, are two important ideas. First, corporate culture speaks to “how” the
firm has decided to do business. Second, corporate culture, expressed through the core values of a
firm, helps to explain “why” the business should exist, not just from the owners’ perspective, but
for everyone who has a stake in the well-being of the firm.How does corporate culture impact the
quality of products and services produced by a firm and, therefore, its capacity to survive There
are three key ways that culture impacts this relationship. First, as noted above, firms vary in
“how” they like to do business, and these choices make a significant difference in the quality of a
firm’s products and services from year to year. The first widely recognized evidence about this
relationship came out in the early 1980s, when Thomas Peters and Robert H. Waterman published their
bestseller book, In Search of Excellence. In looking closely at many consistently profitable,
high-growth firms across several industries, they discovered that all these companies had a
remarkably similar way of doing business that enhanced their reputation as quality providers.
Specifically, they all shared, in large measure, eight common ways of conducting business: a bias
for taking action rather than overanalyzing issues; a drive to get close to customers; the
willingness to grant employees sufficient autonomy to explore new entrepreneurial opportunities; a
quest to improve productivity by investing in their people; hands-on, value-driven styles of
management; a preference for sticking to businesses they knew how to run; creation of simple
structures and operating with a lean staff; and the granting of operational autonomy at the shop
floor while retaining control over the values of the firm at large.

Core Values Impact Quality And LongevityThe second way corporate culture impacts quality and
longevity was only discovered during the past decade. This connection has to do with understanding
“why” an organization should exist at all. More precisely, in a landmark study that compared the
small handful of high-quality companies that had existed for over 100 years – like DuPont –
compared to the millions that go out of business during the first 20 to 30 years of life, the only
consistent differentiating factor was the nature of the core values that were held as being of
primary importance to the firm. Specifically, when a company is aimed primarily at maximizing
short-term economic gains, it is a high-risk candidate for failure because there is always the
temptation to sacrifice long-term quality for near-term profits. In contrast, when a firm places
primary importance on “changing with the times,” so that a community can be created of individuals
who know who they are and why they hold in common certain values – such as continuously improving
the quality of their products and services – the prospects for long-term survival increase
exponentially
(See “Chas. W. HouseandSons – Striving For Quality,” below).The third way corporate
culture impacts quality and the likelihood of long-term survival stems from the value an
organization places on building systems that both reflect the organization’s core values and are
designed to help ensure the firm will last for the long haul. All of the long-lived organizations
that have been studied to date have placed great importance on this kind of investment in quality
improvement. In contrast, when organizations are “built to flip,” as occurred with many of the
dot.com firms created during the past decade, the end result is less pleasant. What systems need to
be built for a firm to continually enhance the quality of its products and services Research over
the past decade indicates that while many systems can be created, there are four that clearly stand
out as most useful in impacting a firm’s ability to survive and thrive. These systems focus on:
building a deep strategic planning process; creating an intense customer focus that permeates the
organization; enhancing the capacity of a firm to develop its people; and expanding the
organization’s commitment to recognize and reward the efforts of all employees.ConclusionsIn
summary, if you want to make it through these challenging times and thrive over the long term, look
to your corporate culture. Knowing how to improve the quality of your products and services is not
enough. Everyone in your organization must believe and act on this value. So, review and improve
“how” you are doing business. Reflect on and make it clear to employees, customers, shareholders,
and the community “why” you should be in business. Then, enhance or build the systems that will
take your firm to the next level.Chas W. HouseandSons – Striving for QualityChas. W. HouseandSons
Inc., located in the quaint New England village of Unionville, Conn., provides a good example of
how a strong culture can help a firm win in good times and bad. Founded in 1867, over the last
several decades, the company has emerged as a leader in the U.S. market for high-quality woolen and
wool-blend woven felt applications.What is the secret of the firm’s success According to Matt
Bristow, CEO, its longevity is the result of adherence to a basic cultural value that “We are
survivors,” who will change with the times, combined with a prudent set of business practices aimed
at always striving to produce higher quality products and services for their customers. More
precisely, according to Bristow, who bought the firm in 1995 after a distinguished career at The
Stanley Works, its success stems from a culture that is “a blend of long-standing values combined
with the reality of today’s globally competitive marketplace.” In addition, the firm’s ability to
remain in the fight today and do battle tomorrow depends on several key business practices that
reflect its culture: strategic planning, customer focus, as well as developing and recognizing its
employees.HouseandSons’ strategy is based on two key fundamental principals. First, focus on
maintaining and enhancing the firm’s core manufacturing competencies. Second, always be in a
position to make choices around what actions can preserve or strengthen the firm’s leadership
position in its markets. So, for example, when the casino gaming and billiard markets began
changing dramatically over the past five years due to a surge of imports and man-made fibers, the
firm responded by introducing a blend of imported products that could meet or exceed the high
quality standards of home-grown products. This decision was based on the recognition that the firm
could add value to the imported product by performing finishing operations that meet or exceed
market specifications. At the same time, being open to importing allowed the company to explore
opportunities to expand its total product offering by selling other products it did not make.
Another key to the company’s long-standing success has been the concerted drive to establish and
maintain close contact with its customers. For example, the company has actively combined the
efforts of its textile technical and sales engineers to work in unison with its customers’
engineering and product-design staff as a way to identify opportunities to become problem solvers
as well as to improve long-term relationships.

By adhering to basic cultural values, Chas W. HouseandSons Inc. has emerged as a leader in
the U.S. market for high-quality woolen and wool blend woven felt applications.The third key
component of HouseandSons’ business culture is to proactively seek ways to develop and recognize
its employees to the greatest extent possible. To this end, the company provides competitive
industry salaries and a profit-sharing plan, and routinely holds employee-recognition and
communication meetings. Beyond these basics, however, the company has also moved to promote a
culture of greater engagement and accountability by flattening the organization. This has occurred
through the elimination of the position of plant superintendent and similar changes in the sales
and marketing and administrative support areas. At the same time, recognizing employee
contributions has remained a top priority. For instance, in 1996, the company made a key hire of a
textile engineer that allowed it to develop an international sourcing capability. This employee has
since become head of the firm’s textile engineering function. Thus, as new challenges arise, the
company’s leadership, first-line supervisors, and employees can more effectively implement new
business plans through faster product development and a commitment to become ever more
customer-focused.

Editors note: James W. Fairfield-Sonn operates his own consulting practice and is also a
tenured associate professor of management at the University of Hartford, Conn. Fairfield-Sonn
teaches courses in process management and leadership and was voted outstanding teacher of the year
in 1999.His first book, Corporate Culture and the Quality Organization, published by Quorum Books,
focuses on identifying the core activities that are essential to the success of any quality
enhancement effort and how to make them happen in a company or organization.

Covering Nonwovens

The nonwovens industry is using a greater diversity of processes and materials to meet the demands
of its market segments. This statement is supported by the fact that, at the Nonwovens Technical
Conference (INTC) in September – sponsored by the Association of the Nonwoven Fabrics Industry
(INDA), Cary, N.C., and the Technical Association for the PulpandPaper Industry (TAPPI)
International, Norcross, Ga. – the largest concentration of process technology papers focused on
the meltblowing of polymers. Additionally, there were a number of presentations on hydroentangling
and spunbonding. Virtually every process in nonwovens – with the exception of stitchbonding – was
extensively covered.The abundance of such dissertations on process technologies reveals a number of
trends within the industry, such as the growing use of bicomponent fibers. As well, it seems there
is a tendency to use a wider range of polymers and technology combinations to develop new nonwoven
products. Furthermore, there is much stronger interest in nonwoven research and development by
academia, evidenced by the fact that more than one-third of the papers presented at the Baltimore
conference were from colleges and universities.The lead-off paper at the conference was prepared
and presented by Dr. D.K. Smith, principal, Smith JohnsonandAssociates, Salt Lake City. His review
covered U.S. patent activities by company, country and process technology from the years 1996
through 2000. These 403 patents were examined and classified according to the claims and were
assigned to a specific nonwoven technology
(See Figure 2).

 Meltblowing TechnologyMeltblown nonwovens now play a key role in the nonwovens
business, finding use in products ranging from diapers, surgical wraps, protective clothing,
filtration and spill-control procedures.Such products and applications have obviously come a long
way since Van A. Wente of the Naval Research Laboratory, Washington, first produced meltblown
microdenier fibers from organic polymers more than 35 years ago. Meltblowing of polypropylene and
other polymers was further advanced by Dr. Robert Buntin and his associates at Esso Research (now
Exxon) Laboratories in Baytown, Texas, in the mid-1960s and early 1970s.An important development in
the recent history of bicomponent meltblown technology was discussed by John G. McCulloch and John
Hagewood, Ph.D., of Hills Inc., West Melbourne, Fla. Hills installed a 20-inch bicomponent
meltblowing die, which was incorporated in the pack of the Hills spunbond bicomponent pilot line.To
date, Hills has demonstrated the production of the following types of bicomponent meltblown
products:meltblown sheath/core 50/50 polyethylene (PE)/polypropylene (PP);meltblown side/side split
fibers PE/PP;meltblown side/side trilobal poly(butylene terephthalate) (PBT)/PP;meltblown
sheath/core 10/90 PE/PP; andsegmented pie poly(ethylene terephthalate) (PET)/nylon 6.Product
possibilities for bicomponent meltblown nonwovens include:respirators;heat and moisture exchangers
for medical uses;improved filtration media;formation of filter and wicking rods by in-line pellets
to rods process;radiation-resistant medical fabrics;artificial leather starting
materials;cylindrical filter elements; andnanofibers.In further meltblown developments, the
Textiles and Nonwovens Development Center (TANDEC) at the University of Tennessee (UT), Knoxville,
Tenn., is playing an increasingly important role in research and development for meltblowing
processing and the development of meltblown products. In its research, TANDEC took a look at
multi-hole meltblowing lines operating at commercial speeds. According to Randall Bresee, Ph.D., a
UT professor, measurements were obtained on-line at various locations between the die and
collector, as well as off-line from webs. On-line measurements include fiber speed, fiber
acceleration, fiber diameter, fiber temperature and air speed. Off-line measurements include
birefringence, fiber entanglement, fiber orientation and differential scanning calorimetry. These
experimental measurements provide a basis for gaining a greater understanding of the meltblowing
process.Furthermore, TANDEC, in combination with the Ian Carson Shell Coordination Centre S.A. and
Shell Chemical Co., Houston, presented an overview of the development and characterization of
poly(trimethylene terephthalate) (PTT)-based bicomponent meltblown nonwovens. In this study,
PTT-based monocomponent (mono) and bicomponent (bico) webs were produced on Germany-based
Reifenhers Reicofil® bicomponent meltblown line at TANDEC. Thermal and flow properties of PTT were
first examined using differential scanning calorimetry and melt indexer for an effective
experimental design through the Surface Response Methodology (SRM). The processability of meltblown
in a wide range of operating temperatures was investigated.Melt temperature, melt throughput, air
temperature, air-flow rate and distance of collector to die (DCD) were considered as primary
process-control variables. The webs produced, both mono and bico, with polypropylene were
characterized for fiber diameter, bulk density, air permeability, hydrostatic head, tensile
properties and heat shrinkage.Non-round and curly or twisted fibers were observed in the bico
PP/PTT webs by a scanning electron microscope. It was found that the PTT grade studied is quite
suitable for the meltblown process. The PTT/PP-based bico webs showed enhanced barrier properties
and heat resistance.TANDEC also presented, along with the Natick Soldier Center, Natick, Mass., a
study on the process properties of meltblowing polyurethane for military protective apparel
garments. The objective of this work was to develop materials that are stretchable, conformable and
breathable; and have the required barrier protection against biological and chemical agents. The
method chosen to achieve these properties was by meltblowing thermoplastic urethane (Noveon Estane®
58227) on the 6-inch meltblowing line at TANDEC.Three promising processing conditions that were
evaluated produced air and water vapor transport properties that were comparable to those of
Gore-Tex® breathable materials.Spunbound Technology

Spunbond technology is now being practiced throughout the world, thanks to the availability
of turnkey processing units. Polypropylene is still the major polymer used for spunbonded fabrics,
but a wider range of polymers is now being used for the development of specialty products. Bico
fiber technology is now being utilized for both spunbonded and meltblown nonwovens.The focus has
been on spinnable resins, according to Hans GeorgGeus, research and development manager, Reifenher
GmbHandCo. The characteristics of these fiber grades are relatively low viscosity, significantly
high melt stability, excellent purity and homogeneity, as well as a narrow molecular weight
distribution.Use of polyolefins, polyamides and polyesters has become common in the industry.
Within this range of resins, there is the potential to use variations such as copolymers,
terpolymers and blends with materials such as polyolefins and oligomeric materials. Some of the
required properties in combining resinous materials can be found in Figure 3.The shear viscosity
and an elongational viscosity at the given temperature are the most important properties. Other
important items are: the degree of thermal stabilization; the degree of solubility in the second
polymer; crystallization and crystallization speed; and, last but not least, the MFR of the various
polymers.The melt temperature for each polymer can be set differently, until the polymers are fed
into the bico system. Then the two materials are jointly passed through only one temperature. In
practice, this is not a limitation, because the difference between the two set temperatures cannot
continue to be very large, as the temperature of the two polymers will equalize to some degree. The
two major types of processes for making spunbonds are the open systems and the closed systems (See
Figure 4). The most commonly used closed system is the Reicofil III System.

 Bico NonwovensBico products from filament lines are usually produced from side/side,
core/sheath or segmented pie filaments. The different cross sections of these filaments determine
fabric properties. In addition to these properties, the filament shape and cross section need to be
considered. Spunlaced NonwovensThe production of spunlaced nonwovens has practically doubled
between 1995 and 2000, and quadrupled between 1985 and 2000, according to Alfred Watzl of
Germany-based Fleissner GmbHandCo. Spunlace enjoys the highest growth rate of any nonwoven
(See Figure 5).Some spunlaced products can be used directly after they are hydroentangled
and dried, but many fabrics can be enhanced by further processing. Additional processing that can
be applied to spunlaced fabrics includes: impregnation with chemical binders; finishing with
chemicals; dyeing or printing; and thermofusion or heat-setting.An example of a spunlaced line with
fiber opening, blending and two cards is shown in Figure 1. Such a production line can be further
enhanced by adding additional processing lines in-line. Fleissner can supply all of the major
components of a spunlaced line, from hydroentangling through dyeing and finishing.Watzl further
discussed bonding and finishing with chemical binders and chemicals. Chemical binding comprises at
least two steps: first, the binder is applied; then, the bonding process is triggered by a thermal
treatment. Maximum strength in a nonwoven is achieved when all fiber-crossing points are bonded in
a point-shaped form fit. A wide range of additives can be incorporated in the binder systems,
including thickeners, softeners, colorants and flame-retardant (FR) agents.A range of application
methods for applying binders, colorants or other finishing agents includes foaming, spraying and
various wet-application techniques. Special techniques such as print bonding are also employed. In
hot-air bonding, spunlaced nonwovens with increased strength and pilling resistance can be made by
incorporating bico fibers in the blend and thermofusing the lower-melting fiber component by hot
air in single- or multi-drum dryers. This method of bonding nonwovens eliminates the buildup of
binders in the unit, a common occurrence when using chemical binders.Heat-setting can be done in a
hot-air drum dryer when improved fabric dimensional stability is required. Heat-setting is
important when processing polyester fabrics for some applications, such as coating.

 Combining Nonwoven TechnologiesFrance-based Rieter Perfojet is the only nonwoven
machinery producer that makes equipment both for spunlaced and spunbonded nonwovens, according to
Daniel Feroe, area sales manager, and Frederic Noelle, research and development manager. The two
Reiter Perfojet executives discussed how spunlace and spunbond technology can be combined to make
an improved wiping fabric.Rieter Perfojet, in its Jetlace® 3000 machine, has raised the efficiency
of hydroentanglement technology by improved design of the internal chambers within the injector
body. The design of the new 400-bar injector allows for a uniform and turbulence-free flow of water
within the injector body, enabling a more efficient water jet created by the flow of water through
the injector strip.

If It Ain’t Broke, Break It


F
or years we heard “If it ain’t broke, don’t fix it” from managers and, in fact, from most
people working in textile manufacturing. This attitude might seem all right when things are going
well and there is not much to worry about. Costs are in line, revenues are increasing, margins are
good. Not much to worry about, and it’s easy to get comfortable.

But with plants closing and business almost at a standstill, one wonders, “What went wrong?”
or “Why are things like they are?” Could it be that the old “If it ain’t broke, don’t fix it”
mentality contributed to the present state of business in the global marketplace?


Too Comfortable?

Hindsight is always much better than foresight, so one can probably say that it did contribute,
somewhat, to where the industry is today. When comfortable, it is easy to accept the “If it ain’t
broke, don’t fix it” philosophy. Keep trucking along, doing as always, don’t change it. But this
attitude is very dangerous.

Not only is it dangerous for spinners, knitters and weavers, it is dangerous in other
industries as well — steel, automotive, machinery, computers and, more recently, airport security.
It is dangerous because if you are comfortable, operate at the same level or stay where you are for
very long, losing is a near certainty. Competitors are smart. They will catch up. They may get
ahead, and catching up or regaining market share will be difficult.

So, if it ain’t broke, maybe you should break it and work like heck to make it better.


Cotton Prices Move Lower

Demand for U.S. cotton continues to be weak. Quotations for the base grade in the seven
designated markets averaged 32.71 cents per pound. A cotton supplier said, “Cotton prices will
continue to move a little lower. I expect this even though supply might be lower than earlier
estimates. Demand is soft. Many mills are trying to delay shipments of 2000 crop cotton, and a few
mills have cancelled some shipments. This really causes me a problem. On the other hand, a few
mills have fixed some cotton at 33 to 34 cents. So someone thinks that cotton prices are near the
bottom.”


Horizontal Integration Helps Shippers

It seems that many companies are moving from vertical integration (doing everything — yarn
manufacturing through product formation) to a more horizontal organization (doing only certain
things — spinning or weaving or knitting, etc.). During the past several months, the Yarn Market
has observed more and more of this change in company structure.

A weaver responded, “We are doing pretty well, better than most in our business. A couple of
keys are that our inventory is under control and we have very little debt.” When asked about
purchasing yarn, he said, “We look at cost. If it is more cost-effective to buy yarn, we will buy
yarn. We used to be vertically integrated, and today we are buying a lot of yarn and making less
in-house.”

Another weaver recently said, “Our business is going very well. We’re in several markets, and
our customers are doing okay. We recently purchased a plant that complements our business. Plans
are to bring this plant up to ‘state-of-the-art.’ Our investment strategies will determine the most
cost-effective way to do this. We’ll take a look at everything — opening room, card room, spinning
room, weave room, etc.

These areas and all options will be considered — including buying yarn. The goal is to make
money. Thus, the investment strategy directs you to put your money in areas that contribute most to
the bottom line. And that may lead us to buying yarn.”

A spinner said, “I’m glad this is happening.” I would be too. But spinners, beware, you had
better break it and fix it to improve it because your customers are doing and will continue to do
what is necessary to lower costs — including shopping offshore.

Quality Fabric Of The Month: Natural Function


W
oolrich Inc., Woolrich, Pa., established in 1830, is the nation’s oldest, continuously operating apparel marketer and manufacturer. Specializing in men’s and women’s outerwear and accessories, the company recently developed TechnoWool™, a line of wool fabrics whose protective and comfort properties compare with those of other performance fabrics. The fabrics are woven at the company’s mill in Woolrich.

TechnoWool fabrics build on wool’s natural functions of moisture and vapor management, breathability, shape retention, insulation, air impermeability and water repellency, which result from the fiber’s structural features, including its protein basis, natural crimp, resiliency,
hollow core and scaly surface. Special techniques are employed to produce a tightly woven fabric having improved air impermeability and insulation and creating a comfortable microclimate next to the body, according to Woolrich.
The Products

qfom_1120TechnoWool is currently available in four styles, with other styles in development. TechnoWool X is a 16.3-ounce fabric designed for extreme outdoor activities including mountain climbing and backpacking. The crimped yarn creates loops in the tightly woven, textured fabric, which is sponged
to raise the nap. The fabric is wool blended with a bit of nylon to provide additional abrasion
resistance and durability.

Softness is the defining feature of the TechnoWool S series. Made from a blend of merino and lamb’s wool, the sponged and sheared 9-ounce fabrics are soft and drapeable, making them suitable for sportswear as well as outerwear, “casual, but a little bit more dressed up than fleece,”
according to Paula Kosmatka, product design director for Woolrich.

Other styles include the O series of “quiet,” sponged bouclé wool/nylon/polyester fabrics, which have added water and soil repellency and burr resistance for outdoor activities such as
hunting; and the W series of machine-washable wool/nylon fabrics. A wind-resistant laminate that combines a hydrophilic mesh and a collapsible, breathable cell membrane with TechnoWool X or S fabric will be introduced in early 2002. Also in the works are an X-series stretch wool with Lycra® and a washable wool fleece.

Garments made from TechnoWool appeal to consumers who prefer natural fibers over man-made. “ Wool looks nicer and is more classic,” Kosmatka said. In addition, she said, wool is an eco-friendly, renewable resource that is free of dependence on petroleum resources.
