ABSTRACT OF THE DISCLOSURE Fluorocarbon additives are provided which may be introduced into fibrous articles to provide improved anti-soiling, anti-stain, water repellency and/or oil repellency properties which resist abrasion and laundering. The additives may be intro- duced into the fibrous article by incorporation into the melt prior to extrusion of the fiber, or alternatively absorbed into a previously formed fibrous article by contacting the article with a liquid medium containing the additive, optionally followed by annealing the treated article to further improve the article's surface properties.
