POLY (TRIMETHYLENE TEREPHTHALATE) FINE DENIER YARNS

摘要

PROBLEM TO BE SOLVED: To provide poly(trimethylene terephthalate) fine denier yarns.SOLUTION: The present invention relates to fine denier poly(trimethylene terephthalate) feed yarns and drawn yarns, and to the manufacture thereof. The yarns are drawn such that the actual draw ratio is within 10% of the predicted draw ratio determined according to [(elongation to break of the feed yarn)+115]/[(elongation to break of the drawn yarn)+115)].
