A deodorant and antibacterial copper nanofiber yarn and a manufacturing method thereof are provided, the manufacturing method including: providing a raw material, including a polyblend slurry, a nano-metal solution, a plurality of inorganic particles, and a plurality of TPU rubber particles; stirring the raw material into a mixed material; making second metal contact the first metal ion fiber to cause the first metal ion to undergo a reduction reaction to obtain a copper nanofiber yarn; drying the mixed material; performing hot-melt spinning on the mixed material, the plurality of TPU rubber particles, after being hot-melted, being coated on an outer peripheral side of the spun wire to form a first-phase wire; forcibly cooling the first-phase wire; stretching the first-phase wire; air-cooling the first-phase wire to form a second-phase wire; and collecting the second-phase wire to make the wire into a finished deodorant and antibacterial copper nanofiber yarn.

The invention discloses a method for preparing wheat gluten nanofibers, which comprises steps of: (1) dissolving wheat gluten and glycerol monolaurate in a solvent to obtain a spinning solution; the solvent is an aqueous acetic acid solution; a volume percentage concentration of the aqueous acetic acid solution is 40-60%; in the spinning solution, a mass percentage concentration of wheat gluten is 20-30%; (2) carrying out electrospinning with the spinning solution to obtain wheat gluten nanofibers. The wheat gluten nanofibers of the present invention have water stability and antibacterial function, and are obtained by electrospinning with wheat gluten as a raw material, so the wheat gluten nanofibers have good biocompatibility and biodegradability.

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 handheld portable electrostatic device for electrostatically applying a treatment solution to a treatment site of a patient, including a housing and a cartridge removably disposed in the housing. The cartridge includes a cartridge housing and a nozzle for applying the treatment solution. An electrostatic module is provided to electrostatically charge and ionize molecules of the treatment solution of the cartridge. The treatment solution is configured to flow toward the nozzle whereby at least one electrode electrically connected to the electrostatic module physically contacts the treatment solution as it flows therethrough and applies an electrical charge to the treatment solution.

The present disclosure relates to polymer resins, fibers, and yarns with permanent antimicrobial activity, and a method of producing the same. In one embodiment, the antimicrobial polymer resin comprises a polymer having less than 2500 ppm of zinc dispersed within the polymer, less than 1000 ppm of phosphorus, wherein the weight ratio of zinc to phosphorus is at least 1.3:1 or less than 0.64:1.

The present invention relates to an antiviral material including a Cu-M-O compound, in which the Cu at least includes a monovalent-state Cu and the M is at least one element selected from the group consisting of B, Al, Sc, Ti, Co, Cr, Ni, Ga, Y, Zr, In, Rh, and a lanthanoid.

Staple fibers and compositions formed from staple fibers are disclosed herein. The fibers are functionalized with molecules that render fabrics comprising the disclosed fibers hydrophobic, hydrophilic, and/or release molecules upon exposure to an external stimulus. Also presented are methods of synthesizing the same and a fabric comprising woven yarns including the staple fiber.

Provided is a textile made of filament yarn comprising a polymer composition that is durable and reusable having permanent or near-permanent antiviral properties and that includes a polymer, a metal ion, preferably a zinc and/or copper ion, and an optional phosphorus compound, wherein fibers and/or fabric formed from the polymer composition demonstrate antiviral properties and wherein the polymer is hygroscopic. The present disclosure also describes methods of forming the polymer compositions and methods of preparing fibers from the polymer composition.

Described are self-cleaning covers for attaching to passenger seats. Embodiments of self-cleaning covers can include an antimicrobial fabric having at least one antimicrobial fiber interwoven with a second fiber, as well as an attachment element connected with the antimicrobial fabric for removably affixing the cover to the seat. The antimicrobial fabric and the attachment element can be shaped to partially enclose and to removably attach the self-cleaning cover to at least a portion of the passenger seat, such as a seat cushion, armrest, or headrest.
