PROCESSING AGENTS FOR SYNTHETIC FIBERS, AQUEOUS LIQUIDS THEREOF, PROCESSING METHODS FOR SYNTHETIC FIBERS AND SYNTHETIC FIBERS

摘要

A processing agent containing five specified kinds of components including esters and ethers as required components is used in the production or fabrication process of synthetic fibers such that superior spinning property is maintained and synthetic fibers with superior yarn quality and dyeing property can be obtained. Aqueous liquids of such processing agents, processing methods using such liquids and synthetic fibers obtained by such methods are also presented.
