POLYURETHANE ELASTIC YARN

摘要

PURPOSE:To improve resistance to chlorine brittleness of polyurethane elastic yarn and products using the polyurethane elastic yarn and to provide the polyurethane elastic yarn or products using the polyurethane elastic yarn with utility in a chlorine-containing atmosphere. CONSTITUTION:Polyurethane elastic yarn is characterized by 150-40,000ppm calculated as tin atom based on polyurethane elastic yarn of at least one inorganic or organic tin compound by weight. Addition of tin sufficiently maintains characteristics represented by stress retention ratio of polyurethane elastic yarn in a chlorine-containing atmosphere.
