TREATMENT AGENT FOR SYNTHETIC FIBERS AND USE OF SAME

摘要

The purpose of the present invention is to provide a treatment agent for synthetic fibers, which is used during the production of synthetic fibers and has excellent handling properties and excellent traveling stability. A treatment agent for synthetic fibers according to the present invention contains (A) a glycerol ester compound which has a structure wherein glycerol and a straight chain fatty acid having 8-22 carbon atoms are ester-bonded and the ratio of straight chain fatty acids having 16-18 carbon atoms is 90% by weight or more in all straight chain fatty acids, and (B) a branched ester compound which has a structure wherein an alcohol and a fatty acid having 8-20 carbon atoms are ester-bonded and the alcohol and/or the fatty acid has a branched structure in the carbon skeleton. The weight ratio of the glycerol ester compound (A) to the branched ester compound (B), namely (A)/(B) is from 75/25 to 15/85.
