Textile School

A composition for use in surface-treating synthetic or semi-synthetic fiber textile materials comprising an aqueous solution or dispersion of a thermally reactive saccharide/urethane ether having at least one blocked isocyanate group capable of regenerating free isocyanate function upon heating and at least one hydrophilic moiety, said saccharide component being selected from the group consisting of oligo- and polysaccharides, lower alkyl ethers thereof, hydroxy-lower alkyl ethers thereof, lower alkyl/hydroxy-lower alkyl ethers thereof and ionizable group-substituted lower alkyl ethers thereof, said saccharide/urethane ether being formed by etherifying said saccharide component with an etherifying agent having said blocked isocyanate group which is, in turn, a reaction product of a polyisocyanate compound with (a) a blocking agent and (b) a lower alkylene halohydrin or an adduct of epihalohydrin with a lower alkylene oxide.
