A method for fiber modification provided in the present disclosure comprises steps: fibers react with a hypochlorous acid oxidant for development of antioxidant fibers, separate the antioxidant fibers from the hypochlorous acid oxidant and dry the antioxidant fibers for development of modified fibers which feature better oxidation resistance.

Waterproof composite fabrics comprising a textile layer and a continuous polymer layer that comprises adjoining first and second regions with different physical or visual properties, and knife-over-roll coating methods for 5 manufacturing said composite fabrics. The waterproof composite fabrics described are particularly suitable for covering medical support surfaces, for instance mattresses.

A method for plasma ion processing is described, including flowing a gas into porous material; and exposing the gas to a pulsed electric field whilst the gas is in the pores. The pulsed electric field ionises the gas to generate a plasma. The method may additionally include exposing the porous material to a gas so as to generate functionality. The method may additionally include exposing the functionalised porous material to a functional species so as to covalently attach said functional species to the surfaces of the pores.

Porous, binderless ceramic surface modification materials are described, and applications of use thereof. The ceramic surface material is in the form of an interconnected network of porous ceramic material on a substrate. The ceramic material may include a metal oxide, a metal hydroxide, and/or hydrates thereof, or a metal carbonate or metal phosphate, on a substrate surface. The substrate may be in the form of a metal or polymer particulate, powder, extrudate, or flakes.

A fiber structure contains polyester fibers 1 and a hydrophilic polyester resin treatment agent, wherein part 2a of a molecule 2 of the hydrophilic polyester resin treatment agent is absorbed in at least part of the polyester fibers 1, and the remainder 2b of the molecule extends along the surface of the polyester fibers 1 to hydrophilize the surface. The fiber structure has the properties below: (1) antifouling properties of grade 4 or higher according to the gray scale assessment determined by applying 200 g of muddy water, which is a mixture of normal staining soil and sand and distilled water at a ratio of 1:1, to the fiber structure, followed by standing for 24 hours, washing, and drying; (2) water absorbability of 10 seconds or less according to the falling-drop method; and (3) diffusivity of 55 minutes or less according to the diffusible residual water content test (dropping 0.6 mL of water). Thus, the present invention provides a fiber structure not involving curing to keep a good texture while having high antifouling properties, water absorbability, diffusivity, etc.
