Abstract
A method to impart permanent stain resistance to polyamides, including nylon fiber and fibrous articles such as carpet and carpet tile, that includes treating the fiber with an isocyanate under moderate conditions that do not damage other materials that the fiber is attached to. Nylon carpet and carpet tile treated according to this method are highly suited for commercial use because they retain their stain resistance after repeated washings.
