Abstract
Disclosed are spray-on anti-soil formulations, and methods for treating fibers, carpets, and fabrics with the same. The anti-soil formulations comprise a synergistic blend of an anti-soil component and a stain blocker component adapted to be sprayed-on a fiber, carpet, or fabric instead of known exhaust applications. The anti-soil component can be either fluorochemical or non-fluorochemical based, while the stain blocker can comprise any chemical that blocks positively charged dye sites. Fibers, carpets and fabrics treated with the anti-soil formulations exhibit superior anti-soil characteristics compared to sprayed-on fluorochemicals and exhibit similar anti-soil characteristics compared to known exhaust applications.
