Abstract
Fluorochemical urethane compositions comprising one or more fluorochemical urethane compounds, and one or more auxiliary compounds for treatment of a fibrous substrate are described. The fluorochemical compositions are capable of improving one or more of the oil- and/or water repellency, stain- and/or soil repellency and stain and/or soil release properties, with improved durability, of the fibrous substrate treated with the fluorochemical composition.
Claims27
A chemical composition comprising:
- (a) a first component comprising one or more urethane comprising the reaction product of:
- (1) one or more polyfunctional isocyanate compounds;
- (2) one or more hydrophilic polyoxyalkylene compounds;
- (3) one or more silane compounds of the formula:
- X—R1—Si—(Y)3
- wherein
- X is —NH2;
- —SH;
- —OH;
- —N═C═O;
- or —NRH where R is selected from the group consisting of phenyl, straight and branched aliphatic, alicyclic, and aliphatic ester groups;
- R1 is an alkylene, heteroalkylene, aralkylene, or heteroaralkylene group;
- and
- each Y is independently a hydroxyl;
- a hydrolyzable moiety selected from the group consisting of alkoxy, acyloxy, heteroalkyoxy, heteroacyloxy, halo, and oxime;
- or a non-hydrolyzable moiety selected from the group consisting of phenyl, alicyclic, straight-chain aliphatic, and branched-chain aliphatic, wherein at least one Y is a hydrolyzable moiety;
- and
- (4) one or more fluorochemical monofunctional compound;
- and
- (b) a second component comprising one or more hydrophilic auxiliary compounds capable of further improving the oil- and/or water repellency or soil/stain release properties of a fibrous substrate treated with the fluorochemical urethane compounds.
