Abstract
Abstract A textile fabric made from synthetic multifilament yarn, particularly for use in articles of clothing, the yarn having an elongation at break of at least 45%. The yarn may comprise polyamides, polyesters or polyolefins and range in denier from 10 to 500 dtex, the individual filaments ranging from 1.5 to 20. The yarns are advantageously produced by high speed spinning and, though flat, i.e. untwisted and untextured, they can be knit or woven into fabrics from which comfortable garments can be made.
