Viscose rayon is attracting attention as a substitute fiber for cotton from the viewpoint of excellent biodegradability, hygroscopicity and water absorption. Generally, the viscose rayon fiber is obtained by wet spinning after preparing a raw material solution and undergoing a spinning step or the like. For example, a treatment agent for viscose rayon may be added before the spinning process in order to improve the process passability.

従来、特許文献1に開示されるビスコースレーヨン用処理剤が知られている。特許文献1は、ビスコースレーヨン用処理剤として、油脂、アニオン界面活性剤、非イオン界面活性剤等を含む構成について開示する。 Conventionally, a treatment agent for viscose rayon disclosed in Patent Document 1 is known. Patent Document 1 discloses a configuration containing fats and oils, anionic surfactants, nonionic surfactants and the like as treatment agents for viscose rayon.
