Yarn Manufacturing
The initial stageof denim proction is Opening and Blending. Opening begins with baledcotton fiber being separated into small tufts. A blend of cotton fibers is madeon each opening line. These bales are selected high grade cotton to reach optimal yarn strength.
Cotton isdelivered by air suction from the Opening and Blending lines, throughadditional cleaning and blending machines, to the Cards. The major functions ofCarding are to remove foreign matter and short fibers, form the cottoninto a web and convert the web into a rope-like form known as a sliver.
The drawingprocess proces a single, uniform sliver from six card slivers. Theadditional blending, paralleling of fibers and cleaning in this processproces a sliver for Open End and Ring Spinning. For Ring Spinning, however,the sliver must pass through an additional process called Roving.
Cotton Fibers areformed into a yarn by centrifugal action in Open- End Spinning.Indivial fibers are laid down in the groove of a fast spinning rotor andtwisted into yarn. After the cotton fibers are spun into yarn, the yarn is woundinto a large package.
The Open EndSpinning Machines have robots on each side which automatically pieces up(repairs broken ends). On a different track, they have another robot thatautomatically doffs (removes full packages) and starts up a new package.The size and quality of each yarn end are computer monitored to ensure uniformity.
In RingSpinning, the spinning frames receive Roving via a transit system from theroving machine. Yarn is formed from cotton fibers that are twisted togetherafter being drafted by passing between three steel rolls and three rubberrolls. The yarn then is wrapped on a bobbin as it spins on a spindle by use ofa traveler. The relationship between roll speeds, traveler speeds and spindlespeeds controls the amount of twist in the yarn. Ends down levels andproction information are gathered by the Uster Ring Expert System. Thespinning frames automatically doff bobbins full of yarn and send them topackage winding.
Hiyoung also has thecapacity to proce Amsler Open-End yarn, also known as Faux Ring Spun yarn.This technology enables Hiyoung to impart various slub patterns into an Open-End yarn. Denim made fromthis type of yarn has yarn character and surface interest that cannot beachieved with traditional Open-End yarn.
Warp Preparation
In the warpingprocess, indivial strands of yarn are removed from yarn packages prior tobeing gathered into a rope form suitable for dyeing. Indivial strands of warpyarn (the length-wise yarn in a fabric) are gathered into rope form and woundonto a log, thus forming a ball warp.
Two rope-dyeranges enable Hiyoung to proce pureindigo, sulfur bottom, sulfur top, and colored denim yarn. The yarn goesthrough scour/sulfur dye, wash boxes, indigo dye vats, over a skying device (toallow oxidation to occur), through additional wash boxes, over drying cans andthen is coiled into tubs which are transferred to the Long Chain Beamingprocess.
Long ChainBeaming separates the dyed yarn into indivial strands, parallels the strands,and winds them onto a large section beam in preparation for Slashing. TheSlashing process takes section beams, coats the yarn with a starch/waxsolution, and winds the yarn onto a loom beam.
A starch/waxsolution is applied to enable the yarn to withstand the abrasion and tension itwill be exposed to in Weaving. The solution also reces the fuzziness of theyarn, thus eliminating a pilling effect in Weaving.
Weaving
The weavingprocess interlaces the warp (length-wise indigo dyed yarn) and the filling(natural-colored cross-wise yarn) procing 100 percent cotton denim in avariety of weights and styles.
The Finishing Range
The FinishingRange brushes and singes the cloth prior to the cloth entering a finishingsolution. The cloth is then pulled to the proper width, skewed, dried androlled for the next process.
The CompressiveShrinkage process reces the amount of shrinkage in the warp or lengthwisedirection that a finished garment will have after laundering. As the clothenters the machine, it is moistened with water and then fed between a thickrubber belt and a heated steel cylinder where approximately 14 percentshrinkage in the warp yarn takes place. After drying, the cloth is rolled ontoan "A" frame.
Every yard of cloth must passrigid inspection standards. An inspection process is a fabric inspection system, thatevaluates the quality of the denim by identifying visible defects that resultring spinning, weaving, dyeing and finishing at Littlefield. They also log all pertinent informationsuch as lot number and the exact location of the defect on the fabric. Thisinformation then is fed to the cutting tables where they locate the defect. This system greatly reces garment seconds. During the process, the cloth is measured and cutinto rolls of proper quality and size. Each roll is carefully weighed to ensurecorrect weight and yardage per roll.
