The invention provides a filter fabric for providing anti pathogenic properties which has been coated with a composition comprising (a) 0.0001-99.9999% by weight of a compound of such as zinc pyrithione and (b) 0.0001-99.9999% by weight of an additional zinc salt selected from the group consisting of zinc acetate, zinc propionate, zinc oxalate, zinc benzoate, zinc gluconate, zinc ascorbate, zinc citrate, zinc lactate, zinc glycolate, zinc maleate, zinc fumarate, zinc polyacrylate and zinc polymaleate. The invention also provides a composition for imparting anti-viral properties to a breathable substrate material comprising two or more zinc salts selected from the group consisting of zinc acetate, zinc propionate, zinc oxalate, zinc benzoate, zinc gluconate, zinc ascorbate, zinc citrate, zinc lactate, zinc glycolate, zinc maleate, zinc fumarate, zinc EDTA, zinc glycinate, zinc polyacrylate, zinc polylactate, zinc polyglycolate and zinc polymaleate said zinc salts being present in effective amounts to impart anti-pathogenic properties.

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 textile structure including one or more layers of warp yarns interwoven with one or more layers of weft yarns, a durable thermoregulating coating, and a binder that chemically bonds the durable thermoregulating coating to the textile structure. The warp yarns and/or weft yarns include polyester yarns. A method for manufacturing a textile structure includes weaving one or more layers of warp yarns with one or more layers or weft yarns to form a woven textile structure, brushing the textile structure at least two times, applying a binder to the textile structure, and applying a durable thermoregulating coating to the textile structure such that the binder chemically bonds the durable thermoregulating coating to the textile structure. The method may also include heat setting and curing the textile structure to fix the durable thermoregulating coating permanently onto the textile structure.

This invention provides antibacterial and antiviral compositions and methods. The compositions possess prolonged and powerful antibacterial/antiviral functions under light exposure and even under completely dark conditions, while daylight exposures could recharge the functions repeatedly. In some embodiments, compositions of the invention can be employed in personal protective equipment (PPE) such as face masks, biologically self-cleaning air and water filters, medical devices, and products. The biocidal PPE can prevent transmission of infectious diseases such as Ebola and respiratory viruses. In some embodiments, compositions of the invention can be employed in food protectant materials to provide antimicrobial and antiviral bio-protection during food transportation and storage.

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.
