Title:
COPOLYMER, PROCESSING AGENT FOR FIBER, METHOD FOR PROCESSING FIBER, METHOD FOR PRODUCING FIBER PRODUCT, AND TEXTILE PRODUCT
Document Type and Number:
WIPO Patent Application WO/2019/059328
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a copolymer capable of exhibiting high washing resistance against bore fleece. In order to achieve the purpose, this copolymer can be obtained by copolymerizing monomers containing components (a)-(c): (a) at least one among an aromatic dicarboxylic acid and a derivative thereof, (b) a polyol, and (c) a compound represented by general formula (1), and is characterized in that the mass ratio of (a)/(c) is at least 1.7. (1) R1R2R3R4N+ X- (in general formula (1), R1, R2, R3 and R4 are each independently a C1-3 linear or branched alkyl group which may be interrupted by a linking group, a C2-30 linear or branched alkenyl group, -(AO)nH, -(AO)mCH3, or a benzyl group of which one or more hydrogen atoms may be unsubstituted or substituted with a substituent, at least two among R1, R2, R3 and R4 are -(AO)nH, A is one or two or more selected from among C1-4 linear or branched alkylene groups, m and n each represent the average addition molar number of (AO) and are 0.1-20, the sum of the respective n's in each of the -(AO)nH's in the molecule is 2-60, and X- is an anion.)
