Abstract

The invention provides a processing agent for polyurethane elastomer fiber, a method of processing of polyurethane elastomer fiber and a polyurethane elastomer fiber, wherein the processing agent for polyurethane elastomer fiber has excellent dispersion stability,allows less scum and soft sides in post processing, and can adapt recent tendency of high level requirements of excellent production of polyurethane elastomer fibers. A composition comprising a specific slipping agent, specific amino modified silicone, and specific higher aliphatic acid salt, can be the processing agent for polyurethane elastomer fibers.

Description

technical field [0001] The present invention relates to a treatment agent for polyurethane elastic fibers that has excellent dispersion stability, scum generation in post-processing or yarn breakage during unwinding, and polyurethane elastic fibers with excellent processing quality, and polyurethane Processing method of elastic-like fiber and polyurethane-like elastic fiber. Background technique [0002] At present, as a treatment agent for polyurethane elastic fibers, a treatment agent containing amino-modified polysiloxane having an alkyl group, a carboxyl group, an oxyalkylene group, etc. in the molecule has been proposed (for example, refer to Patent Document 1). Particle-sized metal soaps and amino-modified silicones having a methyl group at the end (for example, refer to Patent Document 2), and treatment agents containing highly polymerized amino-modified silicone (for example, see Patent Document 3). However, although these conventional treating agents for polyuretha...
