The invention provides fabrics that incorporate a cold-adapted trypsin derived from a fish or a crustacean, which trypsin inactivates viruses. The fabrics of the invention may be used in the production of various items of self-sterilizing protective equipment including gowns, sheets, curtains, surgical hats, surgical booties and protective facemasks.

The invention relates to antimicrobial and/or antiviral fabric compositions comprising ascorbic acid, citric acid, sodium hypophosphite, or a mixture thereof. The ascorbic acid may be covalently attached to at least one cellulosic portion of the fabric composition. The invention also relates to methods for preparing such fabric compositions.

A method for pretreatment of cellulose-containing textiles characterized by applying an aqueous solution with a pH between 1 and 7 and containing at least one agent for durably changing the surface morphology of the cellulose, preferably a neutral salt.

The object of the invention is a composition for impregnating other materials, rendering them able to shield alternating electromagnetic fields in the range from low frequencies up to radio frequencies, containing an aqueous solution of salt that may form hydrates or a combination of salts, of which at least one forms a hydrate, characterised in that it contains an acrylic and/or styrene-acrylic dispersion and/or silicone emulsion and/or enhancing additives selected from a group containing surfactants and/or aluminosilicates and silicates and/or soluble and insoluble calcium compounds, metal and metalloid oxides, while an alternating field is shielded at least in range from 10.sup.−2 Hz to 10.sup.6 Hz and its application for coating/impregnating fibrous and/or porous matrix and materials containing the thereof.

The present invention relates to a method for preparing a textile finishing agent based on an eco-friendly, renewable, and biodegradable biopolymer, and, specifically, to a method for preparing a textile finishing agent, comprising the steps of: forming, at room temperature, a solution comprising an organic acid and the balance of a solvent; stirring chitosan and a base solvent in the solution; and preparing a solution in which a mineral material is dissolved.

A solid, particulate composition having at least one water-soluble carrier material, at least one fragrance and at least one rheology modifier, wherein the carrier material is a water-containing salt (hydrate) whose water vapor partial pressure at a specific temperature in the range from 30 to 100° C. corresponds to the H.sub.2O partial pressure of the saturated solution of this salt, such that the salt melts at this temperature in its own crystal water. The invention further relates to processes for producing the solid composition, and to a washing or cleaning product including the solid composition. In addition, the present invention also relates to the use of a washing or cleaning product of this kind for cleaning of textiles or hard surfaces, and corresponding methods of cleaning textiles or hard surfaces using a washing or cleaning product of this kind.

A method of producing a laminated body, the method including a coagulant solution deposition step of depositing a coagulant solution on a fiber substrate, and a coagulation step of forming a polymer layer on the fiber substrate by bringing a polymer latex into contact with the fiber substrate having the coagulant solution deposited thereon to cause a polymer to coagulate. As the coagulant solution, a solution obtained by dissolving or dispersing 0.2 to 7.0% by weight of a metal salt as a coagulant and 0.1 to 7.0% by weight of an organic acid in a solvent is used. In the method of producing a laminated body, the metal salt is a polyvalent metal salt. In the method of producing a laminated body, the organic acid is an organic acid having at least one group selected from a carboxyl group, a sulfo group, a hydroxy group, and a thiol group.

A solid, particulate composition having at least one water-soluble carrier material, at least one fragrance and at least one water-miscible organic solvent, wherein the carrier material is a water-containing salt (hydrate) whose water vapor partial pressure at a specific temperature in the range from 30 to 100° C. corresponds to the H.sub.2O partial pressure of the saturated solution of this salt, such that the salt melts at this temperature in its own crystal water. The invention further relates to processes for producing the solid composition, and to a washing or cleaning product including the solid composition. In addition, the present invention also relates to the use of a washing or cleaning product of this kind for cleaning of textiles or hard surfaces, and corresponding methods of cleaning textiles or hard surfaces using a washing or cleaning product of this kind.

An article may include a material having a surface containing at least one zinc oxide and/or salt, and at least one antioxidant. A method of using a mixture including at least one zinc oxide and/or salt, and at least one antioxidant, as bacteriostatic agent may include: applying the mixture to a surface of an article.
