　例えば合成繊維の紡糸延伸工程、仕上げ工程等において、例えば合成繊維の摩擦低減、帯電防止性、集束性等の観点から、繊維の表面に合成繊維用処理剤を付着させる処理が行われることがある。 For example, in the spinning/drawing process, finishing process, etc. of synthetic fibers, a treatment agent for synthetic fibers is sometimes applied to the surface of the fibers from the viewpoint of reducing friction, antistatic properties, cohesiveness, etc. of synthetic fibers. .
　従来、特許文献１，２に開示の合成繊維用処理剤が知られている。特許文献１は、所定のアルキルリン酸エステル類、所定の界面活性剤、及び所定のアルキル基を有する１価脂肪族アルコールを所定の割合で含有するポリエステル系合成繊維用処理剤について開示する。特許文献２は、ポリビニルアルコール又はその誘導体からなるＡ成分と、所定のアルキル基を有するアルキル燐酸エステルカリウム塩又はポリオキシアルキレンアルキル燐酸エステルカリウム塩からなるＢ成分とを必須成分として含み、Ａ成分とＢ成分を所定の割合で配合する紡績糸製造用繊維処理剤について開示する。 Conventionally, synthetic fiber processing agents disclosed in Patent Documents 1 and 2 are known. Patent Document 1 discloses a processing agent for polyester synthetic fibers containing a predetermined alkyl phosphate, a predetermined surfactant, and a monohydric aliphatic alcohol having a predetermined alkyl group in a predetermined ratio. Patent Document 2 contains as essential components an A component consisting of polyvinyl alcohol or a derivative thereof, and a B component consisting of an alkyl phosphate potassium salt having a predetermined alkyl group or a polyoxyalkylene alkyl phosphate potassium salt, and the A component and A fiber treatment agent for producing spun yarn that contains component B in a predetermined ratio is disclosed.

　ところが、従来の合成繊維用処理剤は、合成繊維用処理剤を水希釈液とした際の乳化安定性が低下することにより、析出物等が生ずる場合があった。また、合成繊維用処理剤が付与された繊維表面の粘着が高くなり、紡績不良が生ずる場合があった。また、合成繊維用処理剤が付与された繊維の強度が低下することにより、工程通過不良が生ずる場合があった。 However, with conventional synthetic fiber processing agents, the emulsion stability decreases when the synthetic fiber processing agent is diluted with water, resulting in the formation of precipitates. Furthermore, the adhesion of the surface of the fibers to which the synthetic fiber treatment agent has been applied may become high, resulting in poor spinning. Furthermore, the strength of the fibers to which the synthetic fiber treatment agent has been applied is reduced, which may result in failure to pass through the process.
