    摘要: Synthetic or semi-synthetic fiber textile materials are coated with an aqueous solution or dispersion of a thermally reactive saccharide-urethane composition. The saccharide/urethane composition consists of a saccharide/polyisocyanate adduct having at least one blocked isocyanate group, a saccharide/urethane ether having at least one blocked isocyanate group, or mixture of a saccharide material and a thermally reactive crosslinker thereof.

    摘要: Synthetic fiber-containing fabrics are post-treated by impregnating the fabrics with an aqueous solution or dispersion of a thermally reactive blocked isocyanate group-containing polysaccharide derivative and then baking the impregnated fabrics. The blocked isocyanate group-containing polysaccharide derivative is produced by reacting a hydroxy-alkylated natural polysaccharide with a polyisocyanate compound to form a urethane polymer having at least one free isocyanate group, and then blocking the free isocyanate group with a blocking agent. The hydroxyalkylate natural polysaccharide may be directly reacted with a polyisocyanate compound having at least one blocked isocyanate group.
