FLUORINATION AND SULFO-FLUORINATION OF SYNTHETIC RESINS AND FIBERS ABSTRACT OF THE DISCLOSURE The present invention relates to surface modification of synthetic resin fiberform materials, notably polyamide, poly- ester, polyolefin, and polyacrylonitrile fiberform materials whose surface has been modified by treatment with elemental fluorine, and to the fluorination process. Also, the properties of synthetic resins are greatly improved if treated with a gaseous reaction medium containing from about C.1-20% by volume of elemental fluorine, 0.1-50% by volume of sulfur dioxide and 0-21% by volume of oxygen. Fiber form resins selected from the group consisting of polyamides, polyesters, polyolefins and polyacrylonitriles are surface fluorinated carboxylated and apparently, sulfoxylated.
