    摘要： A process for manufacturing a nonwoven barrier fabric having a first face and an second opposite face, with the steps of applying a primer composition by vapor or aerosol deposition, to the first face of the fabric to form a layer of the primer composition, wherein the primer composition is essentially free of fluorinated compound, and applying a barrier composition comprising at least one unsaturated fluorinated compound by vapor or aerosol deposition to the layer of primer composition to form at least one, and preferably from one (1) to four (4), more preferably two (2) or three (2), layers of the barrier composition on the layer of primer composition and a fabric obtainable according to the process.

    摘要： A method is provided for treating active hydrogen atom-containing polymer fibers or fibrous structures made thereof to permanently improve the antistatic, hygroscopic, dye receptive, soil release, inter-fiber adhesion and bonding, and fabric hand properties of the fibers and structures. The method involves contacting the fibers with an aqueous solution containing at least one unsaturated monomer and having an acid pH and a temperature between about 75.degree. C. and about 100.degree. C. After allowing the solution to uniformly disperse among the fibers, so that the monomer intimately contacts the fiber surfaces, the fiber is affected and has essentially single molecule addition of the monomer pendent to the polymer chain to form a branched polymer, graft polymerization of the monomer on the fiber surface is initiated by a polymerization initiator for the monomer, and the polymerization is continued for a sufficient time to allow substantial graft polymerization of the monomer on the fibers to modify the surface properties of the fibers. The fibers are preferably scoured prior to the treatment process, and after polymerization the fibers are rinsed to remove acid and excess homopolymer prior to dyeing and/or further processing of the fibers. The fibers may be in the form of knitted, woven or nonwoven fabrics, and may include amine-containing and/or hydroxy-containing polymers such as nylon, wool, silk, cotton, cellulosic, acetate and combinations thereof.

    摘要： A method is provided for treating polyester, and acrylic polymer fibers or fibrous structures made thereof to permanently improve the antistatic, hygroscopic, dye receptive, soil release, inter-fiber adhesion and bonding properties of the fibers and structures. The method involves contacting the fibers with an aqueous solution containing at least one unsaturated monomer and having an acid pH and a temperature between about 60.degree. C. and about 100.degree. C. After allowing the solution to uniformly disperse among the fibers, so that the monomer intimately contacts the fiber surfaces, polymerization of the monomer on the fiber surfaces is initiated by a polymerization initiator for the monomer, and the polymerization is continued for a sufficient time to allow substantial graft polymerization of the monomer on the fibers to modify the surface properties of the fibers. The fibers are preferably scoured prior to the treatment process, and after polymerization the fibers are rinsed to remove acid and excess homopolymer prior to dyeing and/or further processing of the fibers. The fibers may be in the form of knitted, woven or nonwoven fabrics, and may include mixtures of fibers such as acrylic yarns and nylon filaments or polyester and cotton staple fiber blends.
