Abstract

------09 / 03 / 2566------(OCR) It is rare for elastic polyurethane yarn to break during tail transfer. An elastic polyurethane yarn winder with a tail, resulting from winding elastic polyurethane yarn onto a bobbin, is one where the ratio (W0 / Wmax) of the winding width (W0) from any 10 meters of yarn within 100 meters from the start of winding to the maximum winding width (Wmax) exceeds 0.900 and is less than or equal to 1.00. ------------
