Abstract
A polymeric reaction product is disclosed that is a silylated polyamine-containing polymer having moieties from fatty acid moieties and/or chain extenders as difunctional organo moieties and free amine moieties and hydrolyzed and/or hydrolyzable organofunctional silane moieties and that is at least water dispersible. The reactants that produce this product are a polyamine-containing polymer with fatty acid moieties and free amine moieties and at least one amine-reactable organo functional alkoxysilane or its hydrolysis products. The former reactant results from the reaction of a polyamine-containing polymer with free amine moieties with fatty acids alone or in mixtures with other fatty acids and/or dimer acids. The polymeric reaction product is combined with a predominant amount of water to form a fiber treating formulation that can reside on the surface of one or more treated fibers.
