Parkdale39 S Commitment Honored

Parkdale’s Commitment Honored
Zellweger Uster honors Parkdale Mills for theinstallation of the 30,000th Quantum
clearer.
 Zellweger Uster, Charlotte, N.C., honored Parkdale Mills, Gastonia, N.C., in
early August for the successful installation of 30,000 Uster® Quantum clearers.The management of
both companies complimented their cooperation in various Parkdale plants, including Parkdale
America and Magnolia Manufacturing.Parkdale conducted a plant tour of the George Bloomquist plant
in Lexington, N.C., which permitted a glimpse at the companys modern yarn-manufacturing facility.
At the same time, it highlighted all installed Zellweger Uster equipment and put the spotlight on
the Uster Quantum clearer.  A Walk Through Parkdale’s Plant

Beginning with the first production stage in the mill, invited guests and press were
introduced to one of the laydown rooms with automatic bale openers from Truetzschler.John Nims,
manufacturing vice president, Parkdale Mills, explained that the cotton comes already perfectly
selected as a laydown. USDA data for every bale is re-tested in Parkdales central lab on an HVI
line.Also, tests on the AFIS tester deliver further valuable information about the desired quality
for the laydown. In this particular plant, a 50-bale laydown is used with Truetzschler BDT019
automatic bale openers. The cotton is mainly Memphis territory cotton. Selected North Carolina and
South Carolina cottons are also used by Parkdale.From bale opening through several cleaning and
mixing stages, also using machinery provided by Truetzschler, the cotton fibers are either directly
conveyed to carding or diverted to the fiber blending lines.At this particular plant, four blending
lines for cotton/polyester are installed. Currently, about 75 percent of the production is
100-percent cotton, and 25 percent of it is cotton/polyester blends.However, the
1.5-million-pound-per-week capacity permits production of a higher percentage of cotton/polyester
yarns 550,000 pounds per week of cotton/polyester versus 950,000 pounds of 100-percent cotton
yarn. 

An amazingly high machine efficiency of 99.9 percent was displayed in the cardroom. The cards
are the previous generation Truetzschler DK760 models. During the entire visitation period, no red
light (which would indicate a machine stop) could be seen.The next stop was the drawing section,
where Rieter RSB 851 auto leveler drawframes perform a superior job, according to Parkdale. Based
on fundamental trials, the company decided to use only single-stage drawing because of quality and
cost issues.The sliver cans are picked up by automated guided vehicles (AGVs) supplied by the
Saurer Group, through Schlafhorst Automation Inc., Holland, Mich. The cans are transported from the
drawing section to an elevator, by which they are transferred to the spinning room on the lower
floor.Parkdale also has installed various Zellweger Uster quality control and Expert Systems. These
indicate various on-line production CVs, sliver weights and spectrograms to indicate drafting waves
and other periodic defects.Zellweger praised Parkdale for doing an outstanding job using Usters
Sliverdata to control and correct defects. Both companies worked closely together developing
applicable software to avoid long, thick places in the yarn.  

Jackie Hill, textile application engineer, Parkdale Mills,demonstrates Zellweger Uster’s
Sliverdata and Expert System. “This [the development lab] is the best tool to maintain
quality,” Nims said.The spinning room provides a clean and bright view of modern yarn
manufacturing. Parkdales goal is to keep its entire manufacturing facility spotlessly clean and to
provide the most efficient air conditioning and lighting. All air conditioning is supplied by
Industrial Air, Greensboro, N.C. Efficient air handling contributes to high yarn quality levels and
provides a comfortable work environment.At the George Bloomquist plant, which incorporates two
yarn-manufacturing facilities in one location, approximately 12,000 Schlafhorst Autocoro
rotorspindles are installed. Each spinning position features the Uster Quantum clearer.The Quantum
clearer delivers continuous control of quality for basic yarn defects and eliminates foreign matter
contamination. The system installed at Parkdale comes with computer-aided yarn (CAY) engineering
and features Expert Data management to perfect the processes. It provides active quality monitoring
and precise productivity control for spinning and winding applications. All spinning positions are
monitored by means of spectrograms and classimat data, and Usters Expert System is used to detect,
analyze, and correct eventual problems.By employing digital yarn clearing with both capacitive and
optical sensing capability in one unit, the Uster Quantum clearer has contributed to setting and
achieving Parkdales quality standards.The parameters can be set precisely to individual customer
needs. Cutting out defects is exactly programmed; therefore, there is no unnecessary waste of yarn.
The Quantum clearer was introduced at ITMA 99. Approximately 300,000 clearers have been sold
worldwide, and Parkdale has now surpassed the 30,000th installed clearer mark.The final stage of
the plant tour went from spinning to yarn storage and, further, to automated yarn palletizing and
packing. Parkdale has invested heavily in automation, which seems to be the common theme throughout
the whole plant. The entire manufacturing facility is run by only 112 employees. Appreciative
WordsBoth sides, customer and vendor, praised each other for the high level of cooperation that was
necessary to reach the goal of delivering the highest quality yarns. Anderson Warlick, president
and CEO, Parkdale Mills, made the pledge to provide superior quality products for customers. Eddie
Bradley, head of the Zellweger Uster Division, and Rudy Kagi, president and CEO, Zellweger Uster
Americas, presented Warlick with a 30,001st Quantum clearer in symbolic recognition of Parkdales
purchase and ongoing commitment to quality in the textile industry.
