    Abstract: An apparatus and method for plasma finishing of fibrous materials including paper and knitted, woven and non-woven fibrous substrates such that desired characteristics are imparted are described. The method includes depositing a monomer comprising at least one fluorocarbon monomer with chemical additives, as required, at atmospheric pressure onto the paper or knitted, woven or non-woven substrate; exposing the monomer on a single surface of the fibrous material to an inert gas, atmospheric-pressure plasma, thereby causing polymerization of the monomer species; and repeating this sequence using multiple sequential deposition and plasma discharge steps to create a layered surface having durability against abrasion for both water-based laundry methods and dry-cleaning methods, and normal wear, without affecting the feel, drape, appearance or breathability of the substrate material. The present method uses a high-power, continuously operating plasma that is 104 times more powerful than the prior art plasma sources utilized in the textile industry, and produces a durable finish with between 0.5 and 2 s of plasma exposure. This is sufficiently rapid to meet commercial fabric processing throughput, and repeated cleaning of the electrodes is not required.

    Abstract: Fabrics are treated with a hydrophobic treatment that includes at least one hydrophobic monomer and a crosslinker. The treatment is low in volatile organic compounds and water. It is a liquid at 22° C. or a suspension having a phase that is liquid at 22° C. The monomer and crosslinker are cured in a free radical polymerization to form a hydrophobic coating on a fibrous substrate.

    Abstract: A method of coating a surface with a polymer layer, which method comprises exposing said surface to a plasma comprising a monomeric unsaturated organic compound which comprises a chain of carbon atoms, which are optionally substituted by halogen; provided that where the compound is a perhalogenated alkene, it has a chain of at least 5 carbon atoms; so as to form an oil or water repellent coating on said substrate. Suitable compounds for use in the methods are compounds of formula (I) where R1, R2 and R3 are independently selected from hydrogen, alkyl, haloalkyl or aryl optionally substituted by halo; provided that at least one of R1, R2 or R3 is hydrogen, and R4 is a group X—R5 where R5 is an alkyl or haloalkyl group and X is a bond; a group of formula —C(O)O(CH2)nY— where n is an integer of from 1 to 10 and Y is a bond or a sulphonamide group; or a group —(O)pR6(O)q(CH2)t— where R6 is aryl optionally substituted by halo, p is 0 or 1, q is 0 or 1 and t is 0 or an integer of from 1 to 10, provided that where q is 1, t is other than 0. The method is particularly useful in the production of oil- and/or water repellent fabrics.
