A method for coating a textile material, said method includes the following steps: a) incorporating activated carbon in powder form into a coating composition including an aqueous solvent and at least one organosilicon precursor, wherein the organosilicon precursor represents from 5 to 50% by volume relative to the whole of the aqueous solvent and organosilicon precursor, b) impregnating the textile material with the coating composition by padding and c) drying the impregnated textile material, characterised in that the coating composition contains no polycarboxylic acid or catalyst.

The invention discloses a waterless fiber dyeing method using supercritical carbon dioxide fluid as a medium. Dry fibers are tightly loaded layer by layer in a porous yarn cage. After dyeing, the fibers are cleaned to remove unfixed dyes by an online way, thereby obtaining waterless dyed dry fiber products with good quality. With the supercritical carbon dioxide dyed by a dye, the invention can not only solve the problems of high energy consumption, high discharge, high pollution in the traditional dyeing process, but also obtain better dyeing effect. The invention has a simple process and convenient operation, which can effectively realize dry dyeing processing. The reaction is mild, avoiding the use of a large amount of water, heat and additives in high concentration, which has the features of being high efficiency and environmentally friendly.

The invention relates to a cellulosic fibre loaded with a biologically active substance formed by the steps of: a) producing a cellulosic fibre loaded with ion exchanger, b) after-treating the fibre thus produced with an aqueous solution of a metal salt which exhibits antibacterial activity and/or antiviral activity, and c) after-treating the loaded fibre with an aqueous fixing solution to convert the metal salt into a water-insoluble form. The cellulosic fibres thus produced can be used to form textile fabrics, wound dressings, sanitary products, specialty papers, packaging or filter materials.

A protective garment, gussets for protective garments, and individual gusset layers, being a moisture wicking layer, a core moisture absorbing layer and a moisture impermeable layer, and combinations thereof. The moisture wicking layer including a double knit fabric wherein a technical face of the fabric forms an eyelet mesh utilising both hydrophilic and hydrophobic yarns and a technical back of the fabric forms an interlock utilising only hydrophilic yarns. The moisture absorbing layer including a sinker terry fabric knit comprising sinker loops with plush loops made form synthetic fibres treated with a hydrolysing enzyme that splits the fibres into fibrils. The moisture impermeable layer including a base fabric knit laminated with a polyurethane sheet.

The present invention relates to a method for modifying a textile yarn or fabric by immobilising a cyclodextrin derivative on said yarn or fabric, said process comprising a step (a) of contacting said textile yarn or fabric with said cyclodextrin derivative and with a bridging agent such as 1,2,3,4-butanetetracarboxylic acid, optionally in the presence of a catalyst such as cyanamide,

to obtain a textile yarn or fabric on which the cyclodextrin derivative of formula (I) is immobilised.

A ply fibrous product comprises at least one ply selected from a nonwoven ply and a tissue paper ply, wherein the at least one ply selected from a nonwoven ply and a tissue paper ply comprises cellulosic fibers comprising an organic polycarboxylic acid and wherein the organic polycarboxylic acid has at least one carboxyl group covalently bound to the cellulosic fibers and at least one free carboxyl group. Due to the presence of covalent chemical bonds between a carboxyl group of the polycarboxylic acid and hydroxy groups of the cellulosic fibers present in all substrates, the ply fibrous products display a long-lasting acidic pH even after having been rinsed with water. In some embodiments a long-lasting acidic pH may be achieved in the nonwovens treated with an organic polycarboxylic acid even after washing with a washing detergent.
