worsted

from Wikipedia, the free encyclopedia

As a worsted yarn is referred to that of the sliver of wool (so-called worsted wool) or other fine animal hair, of synthetic fibers (in particular of polyester - and Polyacrynitrilfasern) or mixtures of these fibers is prepared by the worsted spinning process. The yarns made from the top of cotton are not counted as worsted yarns.

Manufacture and description

The top of the wool is created by combing the raw wool, whereby the short pieces of fiber and impurities (knobs, neps, vegetables, so-called noils ) are removed from the raw material. The fibers are aligned evenly and parallel by repeated pre-stretching, warping, if necessary post-combing and mixing. The sliver is then processed further on special spinning machines and receives its spinning and possibly its twisted twist in a further process step .

The minimum length of the processed wool fibers is 60 millimeters. For soft worsted yarns, fibers of 100 to 125 mm in length are usually used, for hard worsted yarns 125–160 millimeters. According to DIN 60410 are the commercially available intricacies of simple worsted between 105 dtex (Nm 96) and 10,000 dtex (Nm 1), said fineness between 125 dtex (Nm 80) and 2000 dtex are used (Nm 5) frequently. The worsted yarns are usually spun in the Z direction, single-stage twists in the S direction.

Worsted yarns are firm, smooth and even yarns that have little hairiness, i.e. little protruding fiber ends. They are mainly used as threads, especially in high-quality Oberbe clothing ( knitting - and woven ), stocking products , but also increasingly in highly developed functional textiles or home textiles used.
