Abstract
A composition that is preferably an aqueous emulsion is disclosed that comprises:1) a compound of a defined formula comprising a silicon moiety and an epoxy functionality;2) a compound of a defined formula comprising a silicon moiety and an alkoxy functionality;3) a crosslinker of a defined formula comprising a silicon moiety; and4) a catalyst.Upon treating fibers or fabrics with the composition, a condensation reaction product is formed upon reaction with the catalyst at curing temperatures that imparts superior durability, water repellency, and softness to the fibers or fabrics.
