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.

A method of manufacturing a textured element may include (a) collecting a plurality of filaments upon a textured surface to form a non-woven textile and (b) separating the non-woven textile from the textured surface. Another method of manufacturing a textured element may include depositing a plurality of thermoplastic polymer filaments upon a first surface of a polymer layer to (a) form a non-woven textile and (b) bond the filaments to the polymer layer. A textured surface may then be separated from a second surface of the polymer layer, the second surface being opposite the first surface, and the second surface having a texture from the textured surface.

This invention relates to a wound roll of fibrous nonwoven sheet structure comprising fibrous material, the fibrous nonwoven sheet structure suitable for subsequent embossing, the sheet structure being gas permeable, and having a first surface and a second surface; the first surface being surface bonded such that the fibrous material on the first surface has been substantially consolidated and stabilized by heat and pressure, and the second surface being capable of accepting printing, wherein the second surface has a smooth surface free of any embossing; the sheet structure having a particle barrier penetration of below 10%, a Gurley Hill Porosity of 40 seconds or less, and a moisture vapor transport rate of 3500 g/m.sup.2/day or greater.

Nonwoven materials having discrete three-dimensional deformations therein forming protrusions that extend outward from the first surface of the nonwoven material and wide base openings adjacent to the second surface of the nonwoven material are disclosed. At least some of the three-dimensional deformations may have improved protrusion dimensions after compressive forces are applied on the nonwoven material. In some cases, at least some of the protrusions may have one or more holes therein or completely therethrough. Methods of making the same are also disclosed.
