Abstract: A polymeric textile yarn having both moisture wicking and anti-microbial properties, and wherein the yarn is produced by a melt spinning process where an anti-microbial agent, and possibly also a colorant, are intimately admixed with the resin in the extruder. Also, the spinneret used in the spinning process includes a large number of minute cross-shaped openings which act to impart a non-regular cross section to the extruded filaments. The non-regular cross section causes voids to be formed between adjacent filaments when the filaments are gathered together to form a yarn, and the voids serve to wick moisture from the body of a wearer when the yarn is incorporated in a body garment. The yarn may include elastic filaments which are intermingled with the extruded filaments.

Abstract: A procedure for the drafting and interlacing of a series of continuous, thermoplastic yarns, consisting of filaments which are substantially parallel to one another, in the manufacture of warp wound on beams.

Abstract: Chain-weft fabrics and knitted fabrics, with a crepe effect, are obtained from continuous texturized synthetic yarns, substantially non-twisted, having a high "yarn count/no. of filaments" ratio, and a high shrinkage under hot conditions, and particularly yarns of 30-160 Dtex comprising filaments of between 5 and 19 Dtex.
