Title:
WET RUBBING FASTNESS IMPROVER FOR CELLULOSE-BASED FIBERS, METHOD FOR PRODUCING DYED CELLULOSE FIBER USING SAME, AND USE OF SAME
Document Type and Number:
WIPO Patent Application WO/2018/190328
Kind Code:
A1
Abstract:
Provided are: a wet rubbing fastness improver which can improve the wet rubbing fastness of a cellulose-based fiber that is dyed with a reactive dye to a level beyond the limit achieved by the conventional techniques; and a method for producing a dyed cellulose fiber using the wet rubbing fastness improver. The problem can be solved by a first treatment solution of a wet rubbing fastness improver for cellulose-based fibers, which contains (A) a cationic polymeric compound having a structure represented by general formula (1) (wherein Rs independently represent a hydrogen atom or a C1-3 alkyl group which may have a hydroxyl group) or general formula (2) (provided that a compound corresponding to (B) an epichlorohydrin-added cationic polymeric compound as mentioned below is excluded) and (B) an epichlorohydrin-added cationic polymeric compound having a structure represented by general formula (3) (wherein R represents a hydrogen atom or a C1-3 alkyl group which may have a hydroxyl group).
