FINISHING LUBRICANT FOR ELASTIC FIBER

摘要

PROBLEM TO BE SOLVED: To obtain a finishing lubricant capable of producing polyurethane elastic fibers prevented from yellowing and getting brittle due to UV or light. SOLUTION: This finishing lubricant for elastic fibers is such as to contain 0.5-10 wt.% of a stabilizer capable of preventing the elastic fibers from discoloration and/or getting brittle due to UV or light such as a ultraviolet light absorber, hindered amine-based stabilizer, lactone-based stabilizer or hindered phenol- based antioxidant each highly compatible with polyurethanes.
