A prepreg containing a carbon fiber [A] and a thermosetting resin [B], and in addition, satisfying at least one of the following (1) and (2). (1) a thermoplastic resin particle or fiber [C] and a conductive particle or fiber [D] are contained, and weight ratio expressed by [compounding amount of [C] (parts by weight)]/[compounding amount of [D] (parts by weight)] is 1 to 1000. (2) a conductive particle or fiber of which thermoplastic resin nucleus or core is coated with a conductive substance [E] is contained.

There is provided an impregnated natural fiber including a cuticle and an interior lumen, the cuticle circumscribing the interior lumen; and insoluble particulates possessing a preselected property embedded in the fiber. The particulates comprise at least 0.1-30 wt. % of the impregnated fiber and the particulates are embedded on the cuticle and within the lumen of the fiber. The fiber has an increased strength, micronaire value and rate of water absorption. Also provided is a system for surface treating cellulose sliver fibers. The system includes a vessel containing a moist paste which comprises at least one particulate material possessing one or more preselected desired properties, a thickening agent and water. The paste from the vessel is dispensed directly onto sliver fiber ribbon(s). A bore sonotrode generates ultrasonic waves which embed the particulate material(s) in the sliver fibers.

A nonwoven fabric has active antimicrobial and anti-viral agents coated onto it. Alternatively, an active antimicrobial/antiviral agent may be mixed into the barrier coating or fiber polymers themselves that make up the nonwoven material. A primary example is the treatment of an existing fabric having known permeability appropriate for an intended use. Intended uses for this nonwoven fabric include, but are not limited to, as a wearable garment, hair coverings, “booties,” patient cubicle curtains, temporary curtains, instrument wraps, surgical drapes, and blankets, each of which has active antimicrobial protection, thereby allowing the possibility of multiple uses of the fabric product.

The invention relates to an electroconductive staple fibers, fabrics and other substrates. The invention further relates to fibers fabrics and other articles of manufacture produced using the method. The method and articles of manufacture find particular use in functional wearable garments, e.g., outerwear, gloves, and in devices in which electroconductivity is desirable. Exemplary devices include a fiber, fabric or leather substrate or component.

Embodiments of the present disclosure generally relate to coated substrates having, e.g., anti-viral properties, to articles including the coated substrates, and to processes for making such coated substrates and articles. In an embodiment, a coated substrate is provided. The coated substrate includes a substrate having a weight of about 120 g/m.sup.2 or less according to ASTM D3776, mineral oxide particles, iron oxide particles, or both, coupled to at least a portion of the substrate wherein the coated substrate has a breathing resistance (95 L/min, EN 149:2001) of about 6 mbar or less.

According to the present disclosure, a resin product is brought into contact with a treatment liquid containing an antibacterial antifungal compound (A) of a quaternary ammonium salt compound having a molecular weight of not greater than 1500 and, in this state, heat-treated under a normal atmospheric pressure or under an increased pressure, whereby the antibacterial antifungal compound (A) is immobilized on at least a surface of the resin product. Thus, an excellent antibacterial/antifungal finished product having water resistance and laundry durability is provided.

A resin composition for preventing fibers from unraveling according to the present invention comprises ethyl acrylate; poly acrylic amide; poly urethane; methyl acrylate; formaldehyde; antistatic agent; quaternary ammonium; maleic anhydride, and surfactant.

An article includes a substrate with a surface, and a coating disposed over the surface. The coating includes a binder material and a plurality of UV scattering porous polymer particles having pores with a light scattering effective pore size of no more than 100 nm. The coating has a scattering opacity of no more than 20% in the wavelength band from 500 to 3000 nm.

This document discloses an electrically conductive fiber coated with polythiophene and a carbon material. Also disclosed is an article of manufacture incorporating the conductive fiber.

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.
