Patent ID: 8038730

Claim:
A fiber product treating agent comprising (a1) a silicone compound, (b) a polymer compound having a weight-average molecular weight of 1,000 to 100,000, comprising an alkylene terephthalate unit and/or an alkylene isophthalate unit, and a polyoxyalkylene unit, and (c) at least one compound selected from the group consisting of (c1) a tertiary amine compound, or acid salt thereof, or a quaternization product thereof, wherein 1 to 3 groups of 3 or 4 groups bound to the nitrogen atom thereof each represent a hydrocarbon group having 10 to 24 carbon atoms and the remaining group(s) represents an alkyl or hydroxyalkyl group having 1 to 3 carbon atoms and (c2) a cationic water-soluble polymer compound, wherein the mass ratio of (a1) to (b) is (a1)/(b)=80/20 to 99.9/0.1; wherein the polymer compound (b) comprises a monomer structural unit (1-1) of formula (1-1) and a monomer structural unit (1-2) of formula (1-2) wherein the molar ratio of (1-1)/(1-2) is from 10/90 to 90/10: wherein R 1 and R 2 each represent an alkylene group having 2 or 3 carbon atoms, and may be the same as or different from each other, and n is a number of 1 to 150 on the number average.
