Processing agent for high-speed spinning process of elastomer fiber having a take-up rate of 1000 m / min and method for producing elastomer fiber

摘要

Problem to be solved: to improve the solubility of the elastomer fiber and to suppress the dispersion from the elastomer fiber.Solution: when the total proportion of dimethylsilicone, silicone resin and mineral oil is 100% by mass, the dimethyl silicone contains 70 to 99.9% by weight, 0.1 to 25% by weight of silicone resin and 0 to 13% by weight of mineral oil The dynamic viscosity at 30 ° C. is 8 to 70 mm2 / s.No selection
