Abstract:
Process for imparting oil- and water-repellency to fibrous substrates, particularly polypropylene upholstery fabric, which comprises applying thereto an effective amount of a composition prepared by first combining one or more fluorocarbon dispersions or polyfluoroalkyl-containing polymeric latexes containing an anionic surfactant with a nonionic surfactant having an HLB of 15. +-. 3 and then with an amphoteric polymer in an amount sufficient to make the composition slightly cationic, thereby facilitating deposition of said composition to said substrate. An anionic surfactant-containing elastomeric latex may be added so as to impart abrasion resistance.
