ABSTRACT:
False-twist heat-set thermoplastic yarn having between 10 and 100 denier is collected on a pirn using a ring-and-traveller takeup mechanism at a balloon tension between 0.03 and 0.7 grams. The resulting yarn gives improved knitting performance and greatly reduced streakiness in hose and other knitted fabrics as compared to yarn collected at higher balloon tension.
