Abstract

The invention provides an agent for processing polyurethane elastomer fibers capable of providing packaged having improved roll shapes and unwinding property at the time of the production of polyurethane elastomer fibers and of providing polyurethane elastomer fibers with superior smoothness, antistatic property and hot melt adhesive property. The processing agent for polyurethane elastomer fibers contains a specified type of dispersion medium having a mineral oil as its essential component in an amount of 80-99.99 mass % and a dispersoid of a specified type made of urethane compound in an amount of 0.01-20 mass % for a total of 100 mass %, having its average particle diameter adjusted to 0.01-500 [mu]m as measured by a specified method such that packages with superior roll shape and unwinding property can be obtained.

Description

technical field [0001] The present invention relates to a treatment agent for polyurethane elastic fibers, a treatment method for polyurethane elastic fibers using the treatment agent for polyurethane elastic fibers, and polyurethane elastic fibers obtained by the treatment method. In the manufacture of fibers, packages with good roll shape and unwinding properties can be obtained, and polyurethane elastic fibers can be imparted with excellent smoothness, antistatic properties and hot-melt adhesive properties. The treatment agent for polyurethane elastic fibers is a method for treating polyurethane elastic fibers, and polyurethane elastic fibers obtained by the treatment method are disclosed. Background technique [0002] Conventionally, as treating agents for polyurethane-based elastic fibers, treating agents obtained by dispersing solid metal soaps in polydimethylsiloxane or mineral oil, etc. have been proposed (for example, refer to Patent Documents 1 to 3), containing po...
