From The Editor: Textiles: Investing In The Future

By Jim Borneman, Editor In Chief

There is something to the idea that ITMA — perhaps the largest display of textile machinery and technology in the world — sets the stage, every four years, for investment and implementation of a new wave of textile technology. The 2011 show, recently held in Barcelona, yielded great content regarding every facet of the textile industry for Textile World to present to readers.

Leading off with Executive Editor Jürg Rupp’s executive perspectives, TW will feature coverage from the Technical Editorial team from the North Carolina State University (NCSU) College of Textiles. TW and NCSU continue their close collaboration, and ITMA is a special opportunity to showcase
NCSU professionals discussing their areas of technical expertise.

Given the current global economic uncertainty, it is not a slam-dunk that there will be a great surge of investment. However, the progress made in technology can be a game changer for some. Trends of increasing efficiency, productivity and sustainability were clear throughout the show.

And there is a sense that “greener” processing is a smart, cost-effective investment in the future.

As energy, water, chemicals, and manufacturing inputs rise in cost, and productivity reduces labor demands, an interesting opportunity emerges for the future of the textile industry. This
isn’t new, but it is more apparent than ever and is challenging the design and specification of processing lines.

With so much of the textile technology being designed and built in Europe, one wonders what the effects will be on the supply of technology around the globe if the Eurozone continues to
wobble. ITMA offered a healthy view of the possibilities for the zone’s machinery manufacturers — a healthier view than expected — but whether all the interest from attendees will convert into orders remains a question.

In this issue of TW, spinning; circular and warp knitting; and dyeing, printing and finishing are highlighted. These are strong segments in U.S. textiles and present some great investment opportunities to create innovative textile products.

The challenge is in choosing to invest. In the wake of ITMA, the passage of KORUS — the Korea-United States Free Trade Agreement — continued promotion of the Trans-Pacific Partnership, and a hazy view of the economic future create a headwind that is challenging to overcome. But it must be overcome if the U.S. textile industry is to remain viable.

Technology that enables creative, innovative products to emerge is the core of successful investment in this competitive market. Whether they are products based on the fine-gauge knitting developments reviewed by Trevor Little, spinning advances highlighted by William Oxenham, or Peter Hauser’s comprehensive review of dyeing, printing and finishing developments — in Hauser’s review, dyeing using 40-percent less water — new processes can move a product from marginal to profitable.

The highly efficient, highly productive U.S. textile industry didn’t get that way by sitting on the sidelines of investment in technology. It will be interesting to see in the coming months
how the industry responds to ITMA’s offerings and what the market chooses as the winners.

Baltimore Welcomes Specialty Fabrics Industry

The most recent edition of the Roseville, Minn.-based Industrial Fabrics Association
International’s (IFAI’s) annual exposition was held at the Baltimore Convention Center from October
25 to 27. IFAI Expo Americas 2011 — said to be the largest specialty fabrics trade show in the
Americas — saw 340 companies from 18 countries exhibiting their products and services to 5,066
registered participants from 43 countries. According to the organization, expo exhibitors reported
high-quality attendees and new connections made with both vendors and customers.

“IFAI Expo Americas 2011 was a great show for us,” said Dale Spuzzillo, national sales
manager and north central sales manager, Nice USA Inc., a San Antonio-based awning manufacturer.
“We had very heavy traffic in our booth the full three days of the show. Not only did we see many
new customers, but we also had excellent meetings with many major manufacturers at this show.”

IFAI reports educational programs presented at the Advanced Textiles Americas conference as
well as continuing education offerings attracted large audiences. Among the most popular were a
technical session covering sustainability in textiles, a fabric structures symposium on Leadership
in Energy and Environmental Design (LEED®) and Construction Specifications Institute fabric
structure certification, and bonus sessions on specialty fabrics in the global marketplace and
exporting for profit. More than 100 participants attended a special program to see demonstrations
on the show floor before it opened on the last day of the expo.

IFAI Expo Americas 2011 hosted 340 exhibitors from 18 countries and 5,066 attendees from 43
countries.


IFAI’s 2011 International Achievement Awards (IAA), which recognize design excellence in
specialty fabrics’ applications, were presented during the Chairman’s Gala following the expo’s
welcome reception. This year, there were 83 awards — including 33 Awards of Excellence — given to
27 companies in 33 categories. Click

IFAI is gearing up for its 100th anniversary next year. IFAI Expo Americas 2012 will
colocate at the Boston Convention Center November 7-9, with the JEC Americas Composites Show and
Conferences, organized by France-based composites industry association JEC Group. More than 600
exhibitors already have signed up for the combined shows.

“The big news from our show in Baltimore was the incredible enthusiasm for IFAI Expo
Americas 2012, taking place in Boston,” said Mary Hennessy, executive vice president, IFAI. “We
completely sold out the show floor in our sales office and had to expand the floor space to
accommodate latecomers to the sales office.”

2011: Up/Down Year Comes To A Close

For most of the past two decades, it’s been a relatively simple matter for spinners to look back on
any given 12-month period and assess whether it was a year to remember or one to forget.

For 2011, however, that task may not be quite so simple. The past year has been among the
most tumultuous in recent memory. From the beginning of the year, when cotton prices were in the
midst of their meteoric climb to record levels, to the last quarter, when prices were falling just
as dramatically, spinners have had to constantly walk a tightrope balancing supply and demand, cost
and price, and capacity.

“This has certainly been among the most topsy-turvy years in my memory,” said one yarn
broker. “I’ve been around this business for more than 30 years, and I’ve never seen anything like
it.”

Another spinner added: “I don’t think I’ve ever seen such a dramatic change, taking place so
quickly, where there was, essentially, no availability of raw material and very little capacity for
manufacturing. And then, just as quickly, there was absolutely no interest in new orders. Keep in
mind that most U.S. spinners were very busy for at least a year and a half, maybe a little more.
And then everything just stopped.”

Early in the year, according to multiple spinners, manufacturers were selling everything
they could make, across multiple product lines and materials. Open-end yarns, which had been in the
midst of an 18-month lull, were in relatively high demand the first part of the year. And ring-spun
yarns were in such short supply that customers were looking well beyond their normal cadre of
suppliers to find availability.

“There was a legitimate concern in the first quarter of 2011 that we would run out of raw
material before we ran out of orders,” said one spinner. “And our customers know the materials
markets as well as we do. They were taking positions for product they weren’t really sure they were
going to need just to make sure they would have positions with their suppliers. The end result is
that a lot of yarn was sold during the first two quarters of the year, even though cotton was at an
all-time high price.”


Momentum Slowed Midyear


As the year began to play out, several events converged to slow the heady momentum the
industry had established. Consumer spending at retail was lower than expected. And, as new-crop
cotton became available, prices began to fall.

“A combination of factors resulted in a significant slowdown in orders shortly after
midyear,” said one spinner. “And I think we are still seeing these factors affect our business.”
First, he said, much of the inventory that was pushed out the door during the first half of the
year stayed on retail shelves longer than anyone expected. Second, as customers began to see the
downward trending of cotton prices, they began delaying orders until the price of yarn more closely
aligned with the existing spot market cotton prices.

“And that’s pretty much where we are now,” said one spinner. “Our customers see that the
price of cotton is falling very quickly. But what they don’t see, because yarn spinners
front-loaded cotton as a result of increasing demand and supply concerns, is that many mills are
still spinning cotton they purchased at 50 cents more than what cotton is currently selling for.”

One yarn broker said: “The best thing that could happen for spinners right now is for the
price of cotton to go back up to about a $1.50 a pound and then come back down slowly. But,
obviously, that’s unlikely to happen. I think what we all have to wait on now is for inventories to
disappear. At some point – and I would guess this would be as early as the first part of Q1 2012 –
we will begin to see the equilibrium point again.”

Indeed, spinners are cautiously optimistic about the first quarter of 2012. Said one: “I
think you’re going to see inventories at retail get to the point where there will be a substantial
increase in orders at the beginning of the year. I look for 2012 to be a bit more normal than the
previous year.”

Added another spinner: “My retail friends are telling me that the initial days of the
holiday season have been stronger than any over the past few years. If that holds for the duration
of the season, it could be very good news for yarn spinners in the months to come.”

flow, is a global supplier of weaving accessories including drop wires, heddles and frames.
According to Picanol, the division’s product line complements Groz-Beckert’s product portfolio, and
will benefit from better growth opportunities under the new ownership.

The acquisition involves all GTP Greenville (Steel Heddle division) employees. Picanol has
transferred section frame and special heddle production for the papermaking cloth industry from
Steel Heddle to its France-based Burcklé subsidiary, which going forward will be expanded further
as a supplier of accessories including reeds, section frames and twin wire heddles for Picanol’s
weaving machinery.

Picanol’s remaining Greenville activities have been reorganized into a new company, Picanol
of America Inc., which will continue to serve the U.S. market offering sales and service for
Picanol weaving machinery and spare parts.

US BioDesign Offers Services To Medical Device Customers

US BioDesign, Perkasie, Pa., has opened its doors to offer original equipment manufacturing (OEM)
services to the medical device industry. The company will focus on custom designing implantable
textile constructs made of polymeric and/or metallic raw materials for cardiovascular, orthopedic,
general surgery and neurological device applications.

The new company is led by president and CEO Tom Molz and Chief Technology Officer Skott
Greenhalgh, Ph.D., who in 2002 founded Secant Medical LLC — a developer and manufacturer of woven,
knitted and braided custom biomedical textile structures for medical devices, formed as a
subsidiary of Perkasie-based Prodesco Inc. Prodesco and Secant Medical were acquired by United
Kingdom-based Fenner Plc in 2008.

In 2006, Molz and Greenhalgh founded Stout Medical Group, also based in Perkasie, to develop
technologies for the medical device industry.

“All of our competitors are textile companies first, medical companies second,” Molz said.
“These competitors often quote multiple samples to solve their customer’s problem, taking
considerable time and charging significant development fees for these activities. US BioDesign is
set up on day one to be a medical company first and a textile company second. We realize the
importance of working with our customer to support their medical device – quickly and efficiently.”

“US BioDesign has designed and acquired some very unique equipment, including the world’s
largest medical braiding machine,” Greenhalgh said. “With this equipment and the strong skills of
our employees, all industry veterans, we are able to provide many specialized product solutions to
our customers.”

Barcelona: Center Of The Textile Universe In 2011

For nearly two weeks, Barcelona, Spain, was not only the capital city of Cataluña, but also the
capital city of the textile world. Three main events challenged one another: the annual conference
of the International Textile Manufacturers Federation, (ITMF), Sept. 19-20, 2011; the World Textile
Summit the day before ITMA 2011, featuring keynote speaker Kofi Annan, former secretary-general of
the United Nations (UN); and ITMA itself, which took place for the first time in Barcelona, from
September 22 to 29. It is not quite certain whether this massive array of events was for the good
or the bad.

One can say that ITMA Europe confirmed its importance as the number-one performance show of
the global textile machinery industry. The extended chapters are an indication of the trend toward
verticalization in the textile industry. This development was confirmed by exhibitors mainly from
the fiber/yarn and fabric sectors as well as finishing.

ITMAshowfloor

ITMA 2011, held at the Fira de Barcelona Gran Via, presented 1,350 exhibitors showing their
products and services to more than 100,000 visitors from 138 countries.



ITMF Conference


Exactly 100 years ago, the first ITMF conference took place in Barcelona. At this year’s
event, under the motto “New Paradigms in the Global Textile Industry,” it was quite fascinating to
see that those in the inner circle of the global textile industry are changing their minds about
their businesses and the future of the planet. Such thoughts were inconceivable at the same event
some 10 years earlier. Shortages of water, food and power; and reduced wastewater were just a few
of the topics discussed and presented in Barcelona. Nick Earlam, chairman of Plexus Cotton Ltd.,
United Kingdom, mentioned that cotton is heavily in competition with food and crops such as soy and
corn. “Food before fiber,” as he said, becomes very important, mainly for the Third World, as the
population grows and people need food. Recently, the world welcomed the 7 billionth global citizen.
Earlam predicted that cotton will be much more expensive in the future. “In the next 10 years, we
[will be] moving from an overproduction scenario to an overconsumption scenario,” he added.


Connectivity


Other lecturers emphasized the importance of sustainable production, using key expressions
such as more productivity per unit area of land, optimized use of chemicals, and improved fiber
quality and processing. Natural fibers are competing heavily with man-made fibers, some people
said, but this could be the wrong point of view. Different applications require different fiber
materials. If the fibers go together and combine their advantages, the natural fiber world will
survive in the long run. And, said one speaker, in today’s world of connectivity, nongovernmental
organizations (NGOs) are becoming more important to deal with. They can ask instantly the following
questions: Why is a product developed? How is it produced? Where is it produced? If a company can’t
answer these questions immediately, in the near future, it will be in trouble. NGOs can mobilize
millions of people right away through the Internet.


World Textile Summit


The day after the ITMF conference, the first World Textile Summit took place. Of course,
everybody was waiting for the highlight of this event: former UN Secretary-General Kofi Annan, who
served from 1997 up to 2006. For many thousands years, Annan said, textiles have been on the way to
globalization. “We are all in the same boat, even in a cruise ship, and we have to take care for
our planet,” he added. He called on the leaders of the textile industry to take responsibility for
their jobs and their people. Welfare is the key to a better world, not poverty. “Doing good is good
for the business,” he said.

ITMASummitAnnan

Former United Nations Secretary-General Kofi Annan delivered the keynote address at the World
Textile Summit, held the day before the opening of ITMA 2011.


Annan mentioned the old statement that the cotton industry is responsible for 25 percent of
all pesticides used on this planet. This provoked intense opposition from the cotton industry
leaders who were present, as did his statement that the textile industry is the second-biggest user
after agriculture of water, chemicals and other inputs. People from the cotton trade noted that all
of these figures are prejudiced and should not be mentioned anymore, and definitely not by an elder
statesman like Kofi Annan. He challenged the audience by saying: “OK, go and tell us the truth
about it.” At the end of his statement, he mentioned that free and fair trade and transparency are
vital for the further development of the Third World, including the abolishment of subsidies for
cotton in the Western world.


ITMA 2011


The greatest textile show on earth took place September 22-29. It was an event full of
unexpected successes. None of the exhibitors interviewed by Textile World expected such a positive
ITMA Europe 2011. Edda Walraf and Reto Thom of Rieter Ltd., Switzerland, confirmed the show’s
success by mentioning the very high quality of visitors. Hermann Selker of Trützschler GmbH &
Co. KG, Germany, said his company welcomed virtually only decision-makers. André Wissenberg of
Oerlikon Textile GmbH & Co. KG, Germany, mentioned that the visitors were very well prepared
and visitor quality was excellent.

But not only were the spinning people pleased, the manufacturers of finishing machinery such
as Regine Brückner, of Brückner Trockentechnik GmbH & Co. KG, Germany; Thomas Archner of Fong’s
Europe GmbH, Germany; and Klaus A. Heinrichs of A. Monforts Textilmaschinen GmbH & Co. KG,
Germany, underlined the show’s success. Heinrichs said that three days before the closing of the
show, Monforts already had 20-percent more visitors than in Munich in 2007. All interviewed people
confirmed that their expectations for ITMA Europe in Barcelona were entirely fulfilled, or even
exceeded.


Global Show Without China


It was no surprise among the exhibitors interviewed by TW that very few Chinese visitors came
to see the latest innovations. There are some reasons for the absence of the big player in the
textile industry: One is the upcoming ITMA Asia + CITME next year in Shanghai. Other reasons
mentioned by the exhibitors are the recent unpredictable financial market and some visa
restrictions. However, the other Asian countries and the rest of the world were in Barcelona.
Bringing together the visitors’ countries named by all those interviewed, India, Pakistan,
Bangladesh, Turkey, Brazil and other Latin American countries were at the top of the charts, but
people also came from Western Europe — mainly from Germany and Spain — as well as from the Middle
East.

Nevertheless, for all of the interviewed exhibitors, the European market is still an
important one — even more for technical fabrics and nonwovens. But 70 to 80 percent of all exported
equipment goes to Asian countries such as China, India, Pakistan, Bangladesh and Indonesia.
However, for most of the suppliers, this percentage is not that important anymore because they all
have their own domestic production sites in China and/or India.


New Machinery


So what was new? Frankly speaking, not much, with some exceptions, if one looks at spinning,
knitting and finishing. More detailed information about the technology and special features of the
machinery presented at ITMA 2011 is published in separate articles.


Spinning


Walraf mentioned the new Rieter air-jet machine and a new rotor spinning machine as well as a
second-generation large card. This concept has become standard over the last few years. The top
runner, Thom said, was the air-jet machine.

Selker was happy with the excellent feedback for Trützschler’s new TC 11 card, which is said
to produce 40-percent more than other recent cards. He also mentioned the new foreign material
detector SP-FPU, which works with three different sensor types to extract virtually all foreign
material.

Wissenberg noted that the new Autocoro 8 was Oerlikon Schlafhorst’s top exhibit in terms of
technology and feedback from the visitors. “Energy saving is another topic,” he said. “Quality as
such is not the issue, but how to produce high quality in a tight or small place is important.”


Knitting


One of the few true innovations was presented by Mayer & Cie. GmbH & Co. KG, the
Germany-based producer of circular knitting machines. The spinitsystems circular knitting machine
has a cylinder diameter of 30 inches and gauge of E28. The idea is to avoid traditional spinning by
replacing conventional yarn with roving, having a yarn count of Ne 0.7. There are 90 feeders, and
the nominal speed of the knitting machine is said to be 30 revolutions per minute. The machine was
presented in a closed room to a limited number of people, and isn’t ready yet to go on the market.


Finishing


Archner mentioned that automation is the top issue at Fong’s. Most of the company’s finishing
machinery is further equipped with automation to reduce energy, labor costs and, of course, water
and chemicals. In this context, he mentioned the updated model of the Fong’s Jumboflow. However,
the highlight was the Then-AIRFLOW® LOTUS with an L-shaped body. This long-shape machine can
process lightweight material containing up to 50-percent elastane.

For Monforts, heat recovery is one of the hot issues. Heinrichs explained the company’s
automated intelligent system as well as the Matex Eco-applicator. This is an instrument that is
built in just before the dryer element to keep the fabrics as dry as possible.

Brückner mentioned that her company’s new Power Frame Eco drying system was the top runner at
the Brückner booth. “The feedback was extremely elevated thanks to the high level of energy saving
and superior production for lower costs,” she said.


Some Problems And Bottlenecks


Overall, ITMA 2011 was a success. However, some negative points were mentioned by the
interviewed exhibitors. For example, the structure of the halls was not appropriate. There were no
clear signs on the ceilings of the halls. The most significant complaint was made by exhibitors who
had large booths. These companies were placed along the walls, which made, so they said, no sense;
and the decision to arrange the exhibits in that way was said to be rather strange.

And there is still the strange fact that absolutely nobody among the interviewed people likes
the fact that ITMA Asia is held every two years. “But what can we do?” one exhibitor said to TW,
“We have to be there, and it’s ITMA owner CEMATEX [the European Committee of Textile Machinery
Manufacturers] that decides, and not we, the involved people.”


ITMA 2015


The next ITMA Europe will be in Milan in 2015. The press left the presentation announcing
Milan as the location of ITMA Europe in 2015 with some mixed emotions. It will take place later in
the year — November 12-19 — at the Fiera Milano (Rho). None of the interviewed people – not only
the exhibitors but also visitors – likes this timing. And now, everybody can prepare for the next
ITMA, this time in Shanghai. It’s just a few months away, in June 2012.

November/December 2011

ITMA Technology: Circular And Warp Knitting

Knitting technology continues to expand the capabilities for conversion of fiber and yarns into
knitted products. This review of ITMA 2011 looks at major developments that knitting machinery
firms are planning to advance the state of the art. Obviously, there are developments that have
improved capabilities such as production speed and production efficiency, and

Textile World
will review several examples. Other developments continue to push the limits of technology
still further in the relentless pursuit of finer and finer fabrics, but these developments are
clearly focused on one firm —
Groz-Beckert KG. Then,

TW
got to see the knitting inventors that continue to integrate parts of the process that
heretofore have not been accomplished.


Gauge


The finer and finer gauge is being pursued by both the circular and warp knitting sectors.
Finer gauge means finer and more reliable knitting components — especially needle beds, cylinders
and needles. Last ITMA saw the introduction of a 60-gauge circular knitting machine, and this has
since found application in performance fabrics for activewear. This ITMA,
Santoni S.p.A., Italy, showed an 80-gauge machine. The Santoni Atlas was operating
at a 30-inch diameter and 80 needles per inch, with a total of 7,536 needles in the cylinder. At
these finer gauges, there is not space for the traditional sinker, so the sinker has been
eliminated and replaced by special holding-down jacks. This has the added advantage of avoiding the
creation of sinker lines, which can be a problem when knitting fine-gauge.

SantoniAtlas

The Santoni Atlas 80-gauge circular knitting machine’s patented system uses Groz-Beckert
technology and produces a tighter knit compared to traditional knits.


Germany-based Groz-Beckert showed another fine-gauge machine with 80 needles per inch. The
company has developed the ability to make needles that knit at normal knitting speeds and also has
the technology to make cylinders that can accommodate the finer-gauge needles. Groz-Beckert and
Santoni are working on a 90-gauge machine in 30-inch diameter that has 8,472 needles and 88 feeds.
Groz-Beckert had on display a 90-gauge cylinder for which the needle width is only 0.18
millimeters.

It may also be interesting to note that Groz-Beckert has developed a cylinder removal tool
called CylinderMaster, designed for machines with diameters larger than 26 inches. The main purpose
is to be able to remove cylinders easily as well as prevent handling damage, especially for the
finer-gauge cylinders.



Mayer & Cie. GmbH & Co. KG
, Germany, showed the MJ3.2 E DNS 60-gauge
jacquard — claimed to be the first fine-gauge jacquard machine, according to company representative
Axel Brunner. The machine with 48 feeds and 30-inch diameter operates at 20 revolutions per minute
(rpm) and has the standard three-way knitting technique. It is equipped with the open-width fabric
system to avoid center creases on these fine-gauge fabrics. Mayer & Cie. also has introduced
temperature control for the knitting zone by using a water-temperature-controlled system to ensure
precise and reliable needle selection mechanisms.

Warp knitting machinery manufacturers also showed interest in developing finer-gauge
equipment.
Karl Mayer Textilmaschinenfabrik GmbH, Germany, exhibited a 50-gauge tricot
machine, HKS 2-3 E, operating at 3,200 rpm and producing elastomeric fabric using 20-decitex
spandex and targeted for the lingerie market. According to Tim Wollnik of Karl Mayer, this is the
first and finest-gauge tricot machine. He said this is the type of machine used by firms such as
Belgium-based NV Marcel Liebaert for its lingerie fabrics.

Of course, one should compare the production rates of weft and warp knitting, and one way is
to look at the number of knitted loops produced each minute. For the 90-gauge Santoni 30-inch
diameter operating at, say, 30 rpm and 88 feeds, the machine produces 22,366,080 loops per minute.
Karl Mayer’s tricot with 130-inch width, 50 gauge and 3,200 rpm produces 20,800,000 loops per
minute, or slightly less than the number of loops per minute for the fine-gauge weft knitting
machines. Clearly, there are additional factors that dictate knitting system choice, but one can
expect the loop production rate to increase as finer gauges and higher speeds occur. However, for
fine-gauge knitting, warp and weft loop production rates converge.



Improved Production Rate And Efficiency

Improved production rate has come from higher speed almost across the board.
Vanguard Pai Lung LLC, Monroe, N.C., showed its SJ4A-DI3 Super Jumbo machine
operating at 1,750 speed factor, which is 58 rpm for a 30-inch-diameter machine. This speed factor
applies for machines in the 14- to 24-needles-per-inch range, and 1,500 speed factor for 28-cut
machines. The SJ4A-DI3 employs a closed-cam track system that ensures positive needle control and
provides consistent stitch definition. The jersey machine is equipped with angular sinker
technology to improve fabric quality and lower the defect rate, even at the highest speeds. The
Delta machine is equipped with a patented three-level sinker cam designed for high-speed knitting.
Vanguard has also increased the size of the fabric roll that can be produced to approximately 500
pounds. This size enables batch processing of the fabric with a single doff and without the need
for bolt-end seaming in finishing, according to Matthew Yates of Vanguard Pai Lung. Vanguard also
showed high-speed 4-inch-diameter rib and 5-inch-diameter jersey machines. These small-diameter
machines are made for production of fabrics used in the apparel, industrial, medical and packaging
industries, Yates said.

Mayer & Cie. has improved the Relanit 4.0 to achieve speeds of up to 70 rpm, according to
Brunner. Relanit 4.0, with four feeds per diametrical inch, is available in gauges from 18 to 28
and in diameters from 24 to 36 inches. A 15-inch-diameter machine is available on request. As a
component of improving productivity, the Relanit has been equipped with the Mayer Cleaning System,
which uses ambient air to provide a cam cleaning role as well as to keep lint and dirt from
entering the cam and needle area. Improvements have also been made to the positive feed system for
the knitting yarn. The fabric take-up system can accommodate a 230-kilogram roll, allowing a longer
knitting time between doffs.

Mayer & Cie. also showed a new striping machine that efficiently produces striped or
basic fabrics on the same machine. According to Brunner, the S4-3.2R produces striped fabrics in
four and six colors across 1.6 feeds per inch. As long as all feeds are striping, the machine uses
1.6 feeds per diametrical inch. However, if a part of the fabric is non-striped, those feeds can
knit with 3.2 feeds per inch; or when striped fabrics are not needed, the machine can produce basic
fabrics using the 3.2 feeds per diametrical inch. This approach provides an optimized solution for
increased production as well as a more flexibly configured knitting system. The S4-3.2R is
available in 24-, 30-, and 34-inch cylinders and from 18 to 36 gauge.



Mec-Mor
, now included in the
Santoni Group, showed a circular machine in 14 gauge as part of its move to
sportswear, according to Patrick Silva Szatkowski, marketing manager for Santoni. This machine can
produce fabric for one polo shirt in 3.5 minutes, making it one of the most productive sportswear
fabric machines, he said.


Mattress Ticking Machines


The use of knit fabrics for mattress ticking continues to be an important market for knitting
machine builders. Mayer & Cie.’s OVJA 1.6 EM and 1.6 EE machine models have been configured in
larger cylinder diameters — including 38 and 42 inches for the OVJA 1.6 EM, and 48 inches for the
OVJA 1.6 EE — in gauges from 18 to 20 for the OVJA 1.6 EM and 18 to 28 for the OVJA 1.6 EE. While
both models are electronic, the OVJA 1.6 EE has full electronic control of both cylinder and dial
needles. The short changeover time offers the possibility for smaller batches, according to
Brunner, as well as the production of large batches when applicable.



Terrot GmbH
, Germany, showed model UP592M, a 38-inch-diameter 20-gauge machine using
a mini-jacquard selection system on the cylinder, for knitting mattress ticking. This model
typically can produce 60.9 meters per hour of mattress ticking fabric weighing 282 grams per square
meter.

Knitting machines for mattress ticking are getting larger in diameter to satisfy the width
requirements for the larger-size mattresses.


Seamless Knitting


The Santoni Group has continued to advance knitting technology and offered many examples of
new ways to make seamless garments. Santoni model SM8-TR1 now offers transfer on a single-jersey
machine. Other knitting capabilities are available thanks to the eight feeds on the same course,
including knit-miss-tuck plus fishnet or anti-drop stitch structures or pattern with floated yarn.
The set-up can be two technical ways — such as knit and miss — plus fishnet or anti-drop structures
with the possibility of inlaid knit work on all feeds. The capability of the machine is limited
only by the imagination of those fortunate to work with one.

Of special interest in the small-diameter knitting sector was Italy-based
Sangiacomo‘s model HT2 for the production of true heel-and-toe socks. The HT2 is a
two-feed, 3.75-inch or 4.0-inch machine with eight striper units and eight electronic needle
selection stations so that the designer can have individual needle selection on any part of the
sock. The machine produces a sock every 2 minutes 15 seconds. The special development from
Sangiacomo is the onboard toe linking unit, according to company representative Sergio Zanoni. Once
the sock is knitted, it is turned and placed on the onboard linking unit, the toe is linked, and
the completed sock is ready. Although the toe-closing operation has been substantially automated,
it still involves operator loading and a separate batch process. This new development of onboard
linking offers an integrated approach and combines and automates several labor-intensive steps at
the knitting stage.

While warp knitting has had technology to produce garments for some years, there is evidence
that this approach is receiving new attention. Karl Mayer showed Model DJ 6/2 with six needle bars
in 44-inch width and 28 gauge for the production of jacquard seamless garments and shapewear by
selectively placing elastic in areas of the garment that require extra support. Santoni also showed
its warp-knit seamless machines including SWD 4/2J four- bar and SWD 6/2J six-bar 44-inch-wide
machines in 24 gauge. As noted earlier, there are productivity gains if a portion of the seamless
market can be converted to double-needle-bar warp knitting when the loop production rate is higher
for a warp-knitting approach than for a weft-knitting approach.


More Integration


In addition to the type of integration offered by Sangiacomo, other knitting machine
producers showed integration from a different perspective. Mayer & Cie. is developing a
machine, dubbed spinitsystems, that backward-integrates into the spinning process
(See “ITMA Technology: Staple Spinning,”). The circular single-jersey machine houses
roving bobbins in the place of yarn packages and spins the yarn on the knitting machine, Brunner
said. The spinning system is air-jet and can spin yarn from 40 to 70 Nm. As is well-known, yarn
delivery speeds from air-jet spinning systems can reach 450 meters per minute, which far exceeds
the rate of yarn demand by a knitting zone. The machine is equipped with sensors that detect when
the roving runs out, and it can electronically remove that feed from knitting until the new roving
is in place and producing yarn again. A yarn vacuum system prevents unused yarn from contaminating
the other knitting zones or the fabric. The concept has merit — especially the flexibility to
change yarn size both within the fabric and between fabric styles. Further, it offers the
capability to produce short runs with a designated yarn size or as a R&D tool for fabric
development. Equipment to produce or transport roving is needed to be able to load this type of
knitting machine, and a reliable supply of air is required to operate the spinning system.

Vanguard Pai Lung has also entered this area of integration and has built a machine that uses
sliver instead of roving. The machine was at ITMA, but behind closed doors.

Clearly, this type of integration heralds a new era for the entire textile complex,
especially the ability to spin on the knitting machine. This raises the question as to whether
spinners will become knitters or knitters will become spinners. Either way, it’s time to build a
strategic model for knit fabric production as the industry goes forward.



More To Come

Advances from the knitting sector continue at an impressive rate. In addition to the
innovations highlighted in the circular and warp knitting sectors, there were many additional
developments at the exhibition, and those merit a separate discussion that will be included in a
future issue of
