SCOURING AGENT COMPOSITION, MANUFACTURING METHOD OF SCOURING AGENT AND PURIFICATION METHOD OF FIBER

摘要

PROBLEM TO BE SOLVED: To provide a scouring agent composition used in scouring a raw material fiber containing a silicone component, capable of suppressing embrittlement of the raw material fiber by suppressing remaining of the scouring agent in the raw material fiber.;SOLUTION: A scouring agent composition is used in scouring a raw material fiber and contains an ampholytic surfactant represented by the general formula (1) and water. In the formula (1), R¹, R² and R³ are each independently an alkyl group having 1 to 22 carbon atoms, an alkenyl group having 1 to 22 carbon atoms, an alkylphenyl group having 1 to 22 carbon atoms or an organic group represented by -(AO)_n-R⁵, R⁴ is an alkylene group having 1 to 10 carbon atoms or an alkylene phenyl group having 1 to 10 carbon atoms, Y^- is a carboxylic acid type anion (-COO^-), a sulphuric ester type anion (-OSO₃^-) or a sulfonic acid type anion (-SO₃^-).;COPYRIGHT: (C)2014,JPO&INPIT
