Spin Finish for Synthetic Fibers and Synthetic Fibers Treated with the Spin Finish

摘要

The present invention relates to a spin finish for synthetic fibers composed of quaternary ammonium salts of organic carboxylic acids and to synthetic fibers treated with the spin finish, wherein the spin fibers are used during the formation and processing of synthetic fibers during the step The scum and tar that can be produced are reduced, and the spin finish is used in forming and processing the stretch woven yarn, which is performed by heat-treating the yarn at a high temperature, the spin finish of formula (1) Characterized in that it may comprise a compound and optionally a polyether-type lubricant.;(Wherein R ₁ to R ₄ are each an alkyl or alkenyl group having 1 to 12 carbon atoms and X ⁻ is an anion of an organic carboxylic acid.)
