ABSTRACT:
A significant improvement in stain-resistance is obtained by commercial application of stain-blocker to nylon carpet that is installed, as opposed to immersing or otherwise treating the primary carpet or treating the precursor nylon polymer or fibers earlier during a manufacturing process. There are various methods of application and of increasing stain-resistance of installed carpets, as well as processes for disinfecting and deodorizing carpets while also imparting stain-resistance.
