Abstract
The present invention relates to fiber treatment compositions comprising an unsaturated acetate, an organohydrogensiloxane, a metal catalyst, and a dispersant selected from the group consisting of one or more surfactants and one or more solvents. The compositions of the present invention impart beneficial characteristics such as slickness, softness, compression resistance and water repellency to substrates such as fibers and fabrics.
Claims10

- (A) an allyl ester, vinyl ester, or an unsaturated acetate selected from the group consisting of isopropenyl acetate and 2-methyl-1-butenyl acetate,
- (B) at least one organohydrogensiloxane,
- (C) at metal catalyst, and
- (D) a dispersant selected from the group consisting of:
- (i) sufactants;
- and
- (ii) an acetonitrile solvent;
- (II) applying the mixture from (I) to a substrate;
- and
- (III) heating the substrate.
