FIBER TREATING AGENT AND FIBER TREATED WITH THE SAME

摘要

A fiber treating agent which not only prevents polyamide fibers and the like from suffering scum deposition on the fiber surface during long-term storage to thereby prevent the fibers from fluffing or breaking during post-processing and from giving a knit of reduced quality, but imparts high collectability to synthetic fiber filaments. The treating agent contains either (a) a urethane compound obtained from a C12+ polyhydric alcohol and an organic diisocyanate or (b) an amide compound obtained from a C12+ polycarboxylic acid and an organic diisocyanate. Especially preferably, the urethane compound is one obtained from a dimer alcohol having a molecular weight of 300 to 1,000 and an organic diisocyanate, while the amide compound is one obtained from a dimer acid having a molecular weight of 300 to 1,000 and an organic diisocyanate.
