TREATMENT FOR ELASTIC POLYURETHANE FIBERS, AND ELASTIC POLYURETHANE FIBERS TREATED THEREWITH

摘要

A treatment agent for elastic polyurethane fibers comprising a dispersion in which a higher fatty acid magnesium salt is colloidally dispersed in a silicone mixture consisting of a silicone oil with a viscosity of 5 x 10 <-6> - 50 x 10<-6> m<2>/S at 25 DEG C as a dispersion medium and a dispersant mainly comprising a modified silicone at a ratio by weight of the dispersion medium/the dispersant = 100/0.5 - 100/4.5, where in the amount of the higher fatty acid magnesium salt is 1 to 10 parts by weight per 100 parts by weight of the silicone oil.
