A METHOD OF PROCESSING SYNTHETIC FIBERS, SYNTHETIC FIBERS, A METHOD OF SPINNING SYNTHETIC FIBERS AND SPUN YARN

摘要

The present invention supplies a method of processing synthetic fibers that can suppress scum accumulation substantially in the high-speed spinning of synthetic fibers and give good high-speed spinning capabilities to the synthetic fibers; the synthetic fibers obtained with said processing method; a method of spinning said synthetic fibers; and a spun yarn obtained with said method of spinning. In the high-speed spinning of synthetic fibers, the processing agent containing an organophosphate metal salt is applied to the synthetic fibers in a specific process in the upstream and, further, the processing agent containing a lubricant is applied in a specific process in the midstream.
