Polymeric articles including fibers, films, and solid surfaces may be produced with improved properties by embedding particles within the article. The particles may be any particle that imparts desired properties to the fiber, film, or solid surface. Methods of selecting the particle size based upon the desired properties of the article such as the fiber diameter, film thickness, efficacy such as antimicrobial activity of the article, and/or article compositions are also described. For example, fibers having improved antimicrobial, antiviral, and antifungal properties are described. The articles having antimicrobial, antiviral, and antifungal properties may comprise a plurality of particles comprising water insoluble copper compounds that release at least one of Cu+ ions and Cu++ ions upon contact with a fluid. The average particle size or the particle size range is selected based upon the diameter of the fiber or thickness of the film to be produced.

Provided is a laminate composite material, comprising a cover layer and at least one fiber nonwoven layer, comprising mineral fibers or thermoplastic fibers and 1 to 45% by wt. of a thermoplastic binder composition to bond together the nonwoven web of fibers, a method for manufacturing the laminate composite material and an insulation product or panel comprising the same. The laminate composite material according to the invention has excellent surface aspect, good acoustic and thermal insulation properties, a good thermoforming and deep shaping performance, dimensional stability and sufficient stiffness at very low weights.

The present disclosure provides composite materials comprising nettings, mattings or meshes thermally bonded to outer layers of nonwoven fibers that may be configured for use in a variety of applications and products. A composite material comprises a first layer of netting comprising intersecting strands and a second layer in contact with the first layer. The second layer comprises first and second fiber components. The first fiber components have a melting point at least 20 degrees higher than the melting point of the netting. The second fiber components have a melting point within 20 degrees Celsius of the fibers in the netting layer. This allows the second fiber components to thermally bond with the netting at contact points upon the application of heat and pressure. The first fiber components do not substantially thermally bond to the netting and thus form an outer layer, such as a sock, that protects the netting layer.

A wound dressing including a needle-punched nonwoven. The needle-punched nonwoven of the wound dressing is 30% to 80% by weight, based on a total weight of the needle-punched nonwoven, superabsorbent fibers. The needle-punched nonwoven of the wound dressing is 70% to 20% by weight, based on the total weight of the needle-punched nonwoven, self-crimped fibers.

Disclosed is a method of producing a rigid package material from textile waste. The method comprises mechanically shredding the textile waste into fibres, the textile waste comprising synthetic textile; blending the fibres with a binder; arranging the blended fibres into a nonwoven web; needle punching the nonwoven web to form a nonwoven felt; and pressing the nonwoven felt thermomechanically to obtain the rigid package material.
