Document Summary
How to create a fabric: from solution, from fibers, from yarns. Drawing-process of stretching manufactured filaments to increase strength; blending and combining several carded slivers into one drawn sliver. Spinning-production of manufactured fibers; process of making yarn from staple. Multifilament yarn-all fibers for one yarn are extruded at once. Staple yarn formation-created through spinning: cotton, opening, cleaning, and blending-bales are opened and cotton fibers are loosened and cleaned, carding/combing-during carding, wires separate and align fibers to form a thin web. Combing further aligns the fibers and makes them more parallel. Creates a yarn that is smoother, finer, and more expensive than carded yarn: drawing-slivers are combined and passed through a series of smooth drums revolving at different speeds. Increases yarn uniformity: spinning/twisting-adds twist necessary to make a yarn, ring spinning-fibers are twisted and wound onto a bobbin in one operation, open end spinning-high speed alternative to ring spinning.
