Description
本発明は、繊維への成分の保持性に優れるとともに、低温ハンドリング性に優れる合成繊維用処理剤の水性液、及びかかる合成繊維用処理剤の水性液を付着させる工程を含む合成繊維の製造方法に関する。 The present invention is a method for producing a synthetic fiber , which comprises a step of adhering an aqueous solution of a synthetic fiber treatment agent having excellent retention of components on the fiber and excellent low temperature handling property, and an aqueous solution of the synthetic fiber treatment agent. Regarding.
一般に、合成繊維の紡糸工程において、摩擦を低減し、糸切れ等の繊維の損傷を低減させる観点から、合成繊維のフィラメント糸条の表面に合成繊維用処理剤を付着する処理が行われることがある。その付着処理の形態は、合成繊維用処理剤を水に希釈する場合（エマルション給油）と、合成繊維用処理剤を低粘度鉱物油等の希釈剤で希釈又は希釈せずそのままの状態で付与する場合（ストレート給油）がある。 Generally, in the synthetic fiber spinning process, a treatment for adhering a synthetic fiber treatment agent to the surface of the filament yarn of the synthetic fiber is performed from the viewpoint of reducing friction and reducing fiber damage such as yarn breakage. is there. The form of the adhesion treatment is that when the synthetic fiber treatment agent is diluted with water (emulsion refueling), the synthetic fiber treatment agent is applied as it is without being diluted or diluted with a diluent such as low-viscosity mineral oil.
