These distortions give synthetic yarns such as nylon, polyester and polypropylene improved properties such as stretch, bulk, improved thermal insulation and an appearance similar to natural fibres. This important book summarises the key principles, technologies and process issues in the manufacture of high-quality false twist textured yarns.After an introductory chapter on the development of textured yarns, the book revi 410 0$aWoodhead publishing in textiles ;$vno. 129. 606 $aTextile fabrics 615 0$aTextile fabrics. 676 $a677 676 $a677.02862 700 $aAtkinson$b Colin$0747056 712 02$aTextile Institute (Manchester, England), 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9911006814503321 996 $aFalse twist textured yarns$94389102 997 $aUNINA
