The invention relates to a method of forming a biodegradable nonwoven fabric, the nonwoven fabric obtained by this method, and a system of devices for carrying out this method, to be used for the manufacture of cellulosic articles for clean-up work and sanitary products, and medical uses.

A method for producing a nonwoven element for hygiene articles is accomplished by the steps of: forming a fibrous web from a multi-ply nonwoven material with at least one carded staple fiber layer and a storage layer which is arranged on the staple fiber layer and which has cellulose fibers, wherein at least a portion of the staple fibers of the staple fiber layer are formed from a thermoplastic; applying liquid jets to the fibrous web, as a result of which the fibers of the multi-ply nonwoven material are intermingled and entangled, and the fibrous web is embossed with a surface structure; applying heat to the fibrous web, as a result of which the thermoplastic staple fibers at least partially fuse and the fibrous web is bonded to form a nonwoven web, and severing individual nonwoven elements from the nonwoven web.

The present invention provides a non-woven fabric for supporting a solid electrolyte in which heat-fusible composite fibers with a crimp are contained in an amount of not less than 60 mass % and not more than 100 mass % and are heat-fused, and a solid electrolyte sheet. The non-woven fabric for supporting a solid electrolyte is excellent in process performance, is satisfactorily filled with a solid electrolyte, is suitable for achieving a thin solid electrolyte sheet, and has few hole defects. The solid electrolyte sheet is excellent in self-sustainability and flexibility.

The present disclosure relates to a dielectric substrate that may include a resin matrix component, and a ceramic filler component. The ceramic filler component may include a first filler material. The particle size distribution of the first filler material may have a D.sub.10 of at least about 1.0 microns and not greater than about 1.7, a D.sub.50 of at least about 1.0 microns and not greater than about 3.5 microns, and a D.sub.90 of at least about 2.7 microns and not greater than about 6 microns.

Nonwoven materials having at least one layer comprising cellulose fibers are provided. The nonwoven materials comprise bonded natural cellulosic fibers having high capillary action. The nonwoven materials are suitable for use in a variety of applications, including absorbent products and pre-moistened cleaning materials with metered release of liquid.

A nonwoven fabric structure according to the present invention is a nonwoven fabric structure comprising a long-fiber nonwoven fabric as a main constituent, wherein the nonwoven fabric structure has a basis weight of 250 to 2000 g/m.sup.2, a Frazier permeability of 0 to 20 cc/cm.sup.2.Math.s, and an apparent density of 0.5 to 1.3 g/cm.sup.3, and therefore has excellent shaping properties and excellent mechanical strength properties.

Disclosed is a method for producing a prepreg, the prepreg having: a reinforcing fiber layer including reinforcing fibers and a resin composition containing component (A), component (B), and component (C), the reinforcing fibers being impregnated with the resin composition in between the fibers; and a surface fiber layer provided on the surface of the reinforcing fiber layer and including a fabric including polyamide fibers and a resin composition containing component (A), component (B), and component (C), the polyamide fibers being impregnated with the resin composition in between the fibers. The method for producing a prepreg includes a disposition step of disposing the fabric on the surface of a reinforcing fiber base material and an impregnation step of supplying a resin composition to the reinforcing fiber base material and impregnating the reinforcing fibers with the resin composition in between the fibers.

A carpet and a method of making a carpet are described. The carpet and the method of making the carpet does not involve the use of a latex precoat. This is useful for recycling purposes.

This depth filter comprises a substrate layer, a filtration layer, and a skin layer in this order. The substrate layer and the skin layer are layers obtained by winding and thermally fusing a nonwoven cloth configured from fibers having an average fiber diameter of 150 μm or more. The filtration layer is a layer obtained by winding a layered body two or more times, the layered body containing at least a net and a nonwoven cloth included only in the filtration layer. The average fiber diameter of the nonwoven cloth constituting the substrate layer and the average fiber diameter of the nonwoven cloth constituting the skin layer are larger than the average fiber diameter of the nonwoven cloth included only in the filtration layer.

A vehicle exterior member having a self-neutralizing function which can improve running characteristics and steering stability of a vehicle without impairing the design property has a fiber molded member containing a needle-punched nonwoven fabric or knitted fabric. The fibers constituting the fiber molded member contain a conductive fiber.
