TREATMENT AGENT FOR SYNTHETIC FIBER FILAMENTS SYNTHETIC FIBER FILAMENTS AND BASE FABRIC

摘要

The object of the present invention is to reduce fluff or fibrillation in the weaving process of synthetic fiber filaments, and for synthetic fiber filaments having excellent refining properties of the base fabric from which synthetic fiber filaments are woven. It is to provide a treatment agent, to provide a synthetic fiber filament to which the treatment agent is imparted, and to provide air bubbles woven from the synthetic fiber filament. A group consisting of an ester compound (A1) that is a condensation product of a polyoxyalkylene group-containing hydroxy fatty acid polyhydric alcohol ester and dicarboxylic acid, and an ester compound (A2) that blocks at least one hydroxyl group among the condensates with fatty acids. For synthetic fiber filaments containing essentially at least one ester compound (A) selected from, and an ether ester type ester compound (B), and containing (A) and (B) in a specific ratio and a specific total weight ratio. It was found that the treatment agent had little fluff or fibrillation and was excellent in refining properties.
