TREATING AGENT FOR ACETATE YARN AND ACETATE YARN PROVIDED WITH THE TREATING AGENT

摘要

PROBLEM TO BE SOLVED: To obtain both a treating agent for an acetate yarn, capable of greatly improving flying qualities in an AJL, having a slight dispersion of flying qualities in the length direction of yarn and an acetate yarn provided with the treating agent. SOLUTION: This treating agent comprises 30-60 wt.% of a liquid paraffin (component 1) which is composed of 5-20 wt.% of a 9-18C liquid paraffin and 80-95 wt.% of a >=19C liquid paraffin and has 12-25.0 cSt viscosity at 30 deg.C, 30-60 wt.% of a fatty acid ester (component 2) having 6.0-15.0 cSt viscosity at 30 deg.C, 5-15 wt.% of a compound (component 3) obtained by blocking a terminal hydroxy group of an adduct of ethylene oxide to an alcohol with an aliphatic carboxylic acid and 5-10 wt.% of an alkylphosphoric ester amine salt (component 4). This acetate yarn is provided with 0.5-2.0 wt.% of the treating agent.
