Abstract:
1. An agent for processing polyurethane elastomer fibers, said agent consisting of 80-99.99% by mass of a disperse medium and 0.01-20% by mass of a dispersoid for a total of 100% by mass, said dispersoid being prepared so as to have an average particle size of 0.01-500 μm as measured by a specified measuring method; wherein said disperse medium is a liquid consisting of 70-100% by mass of mineral oil and 0-30% by mass of silicone oil and/or liquid ester oil for a total of 100% by mass and having a viscosity of 2×10 wherein said dispersoid is one or more aliphatic compounds having a melting point of 25° C. or above selected from the group consisting of aliphatic ester compounds shown by Formula 1, aliphatic ester compounds shown by Formula 2, aliphatic ester compounds shown by Formula 3 and aliphatic ester compounds shown by Formula 4 where Formula 1 is R and Formula 4 is where R 1 is a straight-chain aliphatic hydrocarbon group with 14-50 carbon atoms, a branched aliphatic hydrocarbon group with 14-50 carbon atoms or cycloalkyl group with 5 or 6 carbon atoms; A is a residual group obtained by removing all hydroxy groups from (poly)oxyalkylene glycol with 2-30 carbon atoms having within its molecule (poly)oxyalkylene group formed with oxyalkylene unit with 2-10 carbon atoms; X 1 is an acyl group shown by Formula 5, which is R 2 being a straight-chain aliphatic hydrocarbon group with 13-49 carbon atoms, a branched aliphatic hydrocarbon group with 13-49 carbon atoms or cycloalkyl group with 5 or 6 carbon atoms; and X 2 -X 10 are each acyl group shown by Formula 5 or hydrogen atom, at least one of X 2 and X 3 in Formula 2 being acyl group shown by Formula 5, at least one of X 4 -X 6 in Formula 3 being acyl group shown by Formula 5, at least one of X 7 -X 10 in Formula 4 being acyl group shown by Formula 5; and wherein said specified measuring method comprises the steps of obtaining a diluted liquid by diluting said agent for processing polyurethane elastomer fibers by using a 1/1 mixture in mass ratio of polydimethyl siloxane and mineral oil both with viscosity of 10×10
