TREATMENT AGENT FOR SYNTHETIC FIBER, TREATMENT METHOD OF SYNTHETIC FIBER, MANUFACTURING METHOD OF SYNTHETIC FIBER AND UNWOVEN FABRIC

摘要

PROBLEM TO BE SOLVED: To provide a treatment agent for synthetic fiber capable of enhancing stability of an emulsified article of a synthetic fiber treatment agent and water, dispersing a synthetic fiber uniformly when applying the synthetic fiber to which the emulsified article is adhered to a paper making process, and suppressing foaming in the paper making process, a treatment method of the synthetic fiber, and a manufacturing method of the synthetic fiber and an unwoven fabric.;SOLUTION: The treatment agent for synthetic fiber is a treatment agent for synthetic fiber used for a synthetic fiber applied to a paper making process, and contains specific polyether polyester of 50 to 98.99 mass%, a specific ionic surfactant of 1 to 49.99 mass% and a following silicone compound of 0.01 to 20 mass% so that total percentage content of the polyether ester, the ionic surfactant and the silicone compound is 100 mass%.;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
