Disclosed is a malodor control system that can include use of a malodor scavenger configured to sequester a malodor molecule to reduce and/or eliminate the noxious odor the malodor molecule generates. Some embodiments can include use of a substrate configured as a non-woven fabric sheet as a delivery system for the malodor scavenger. In some embodiments, the substrate includes a polymer complexed with active ingredient to lock the active ingredient in place at a surface of the substrate via a binder so that the active ingredient is present at a predetermined activity level. After interacting with malodor molecules, at least some of the active ingredient can migrate via passive diffusion to the substrate surface to maintain the predetermined activity level.

The application relates to a process for producing fibrous material with antimicrobial properties, wherein in the first step coniferous resin acid composition is emulsified into aqueous solution with emulsifier and wetting agent, and in the second step thus formed emulsion is transferred into fibrous material by impregnation. Further, the application relates to an aqueous antimicrobial composition for use as a water-soluble concentrate in the treatment of fibrous materials, and to a fibrous material with antimicrobial properties, and to its use in e.g. fabrics, fur, leather, clothes, canvas, tissues, plastics, webs, accessories, packaging materials, wallpapers, food-related products, household products, footwear, construction materials, insulating materials and medical products.

Insect repellent compositions are provided for resilient use in fabrics. Compositions include an alcohol solvent and an ethoxylated oil mixed with an insecticidal pyrethroid of at least 25% of the composition. Permethrin, benzyl alcohol, and ethoxylated castor oil may be used in ratios ranging from about 2.5:1.5:1 to about 1:1.2:1.8. An insect repellent fabric is prepared by neutralizing the fabric and treating the fabric with the insect repellent formulation. The formulation may include a padding composition mixed with an insect repellent composition. The padding composition includes a polyglycol ether, an acrylic acid ester, an acrylic ester copolymer in aqueous solution, and a cross linking agent. The fabric may be evenly treated with the mixed padding and repellent composition and then dried. The treating may include impregnating the fabric with microcapsules that elute or diffuse the insect repellent and/or padding composition.

A detectable scouring pad is provided that is made with a sparse unwoven base polymer that defines the pad shape, an overcoating of cured thermoset resin loaded with a particulate on the base polymer, the particulate present in an amount to render the polymer detectable by X-ray detection or magnetometer detection. A process of detecting a scouring pad includes forming a fiber composed of a base polymer having a cross-section and a length, and distributing a particulate on the thermoplastic polymer in a thermoset resin matrix. The process further includes forming a sparse unwoven thermoplastic polymer from the fiber, and manufacturing the scouring pad from the sparse unwoven polymer by overcoating the base polymer with a particulate loaded thermoset resin. The scouring pad is passed through an X-ray detector or a magnetometer detector, and a signal is collected from the detector indicative of the presence of the scouring pad.

The invention relates to a method for treating a fabric, notably a method for preventing or recovering degradation of a fabric, by using a natural polygalactomannan.

The present invention relates to at least one fiber (2) used in composite materials; a solution (C) containing a transition metal; at least one barrier coating unit (3) which enables the fiber (2) to be surrounded with the solution (C) by using a dip and/or spray coating method, thereby protecting the fiber (2) surface from chemical and/or physical impacts; at least one deposition unit (4) which enables graphene and/or graphene-based nanoribbons to be bonded with transition metals located at certain distances on the fiber (2) by using the chemical vapor deposition method, thus allowing the graphene and/or graphene-based nanoribbons to adhere to the fiber (2); and at least one iron coating unit (5) which enables application of iron-based nanoparticles on the fiber (2) using the dip and/or spray coating method.

The invention provides a silver-plated conductive nylon fiber and a preparation method thereof. The method includes: immersing a nylon fiber in an aqueous solution containing a polyphenolic compound at 60? C. to 70? C., adding a water-soluble oxidant into the solution, continuously reacting at 70? C. to 80? C., and obtaining a polyphenol grafted nylon fiber, where the polyphenolic compound contains a catechol group; immersing the polyphenol grafted nylon fiber into a solution containing silver ions at 15? C. to 25? C. for reaction, and raising the temperature to 70? C. to 80? C. for continuous reaction to obtain a surface-activated nylon fiber; and carrying out chemical silver plating treatment on the surface-activated nylon fiber to obtain the silver-plated conductive nylon fiber. The method does not require a heavy metal sensitizer and therefore is non-toxic and environment-friendly, and the fiber strength is maintained.
