DURABLE HYDROPHILIC FIBER, CLOTH-LIKE BODY AND FORMED BODY

摘要

PROBLEM TO BE SOLVED: To improve durability of hydrophilic functions of a hydrophilic fiber and strength of fabric obtained from the hydrophilic fiber. SOLUTION: This durable hydrophilic fiber is obtained by applying 0.2-1.0wt.% surfactant composition comprising (A) 10wt.% addition product prepared by adding 5 mole ethylene oxide and 5 mole propylene oxide to a 30C alcohol, (B) 25wt.% addition product prepared by adding 10 mole ethylene oxide to a diamide of behenic acid and diethylenetriamine, (C) 35wt.% stearic acid diethanolamide, (D) 15wt.% potassium lauryl phosphate adduct of 5 mole propylene oxide and (e) 2-10wt.% sodium (14-16C) alkylsulfonate to the fiber made of a thermoplastic resin.
