Fibre treatment compositions

摘要

This invention relates to a fiber treatment composition comprising (A) 100 weight parts of a triorganosiloxy-endblocked dimethylpolysiloxane having a viscosity at 25 DEG C of 2 to 100 mm<2>/s, (B) 1 to 20 weight parts of a metal salt of a fatty acid having from 10 to 20 carbon atoms, and (C) 0.05 to 10 weight parts of at least one organopolysiloxane resin comprising SiO4/2 units and R3SiO1/2 units, wherein R denotes a monovalent hydrocarbon group. These compositions have excellent dispersion stability and impart superior smoothness and antistick characteristics to fibers. They are especially useful in treating spandex fibers.
