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

摘要

A treatment for elastic polyurethane fibers, characterized by comprising a dispersion prepared by dispersing a higher fatty acid/magnesium salt in the colloidal form in a silicone mixture composed of a dispersion medium comprising a silicone oil and a dispersant mainly comprising a modified silicone, wherein the proportion of the salt ranges from 1 to 10 parts by weight per 100 parts by weight of the silicone oil, the ratio of the dispersion medium to the dispersant ranges from 100/0.5 to 100/4.5 (by weight), and the silicone oil has a viscosity ranging from 5 x 10-6 to 50 x 106 m2/s.
