Thermoplastic-poly (dihydrocarbylsiloxane) compositions, and fibers, and processes for making fibers

摘要

Polymer compositions useful as shaped articles such as synthetic yarns are disclosed. The polymer compositions include poly(dihydrocarbylsiloxane) components featuring one or more of octyl, dodecyl, cetyl, behenyl, vinyl, bis-vinyl, vinyl-reacted, or bis-vinyl-reacted substituents. The synthetic yarns have been used to produce tufted carpets having improved performance characteristics, including softness benefits, as well as improved water repellency and soil release.
