CROSS-LINKING AGENTS OF CELLULOSIC FABRICS

摘要

Cellulosic materials such as cotton fabrics and paper are cross-linked with a composition comprising (A) polymers of ethylenically unsaturated polycarboxylic acid monomers or salts thereof, the monomers having one or more dicarboxylic groups wherein the carboxyl groups are on adjacent carbon atoms; (B) saturated alpha -hydroxypolycarboxylic acids or salts thereof; and (C) one or more curing catalysts, and heated to produce esterification and cross-linking of the cellulose by reaction of the cellulosic hydroxyl groups with carboxyl groups in the reaction product of (A) and (B).
