A process for manufacturing a water soluble product including the steps of: providing a water soluble fibrous first ply; providing a water soluble fibrous second ply formed on a surface other than the first ply, wherein the second ply is separate from the first ply; superposing the first ply and the second ply; and joining a first portion of the first ply to a second portion of the second ply to form the water soluble product.

Disclosed is an anti-weed sheet manufactured by forming webs. The web is formed of polyolefin-based staple fibers which are at least one selected from the group consisting of polyethylene staple fibers, polypropylene staple fibers, and polyisobutylene staple fibers. The sheet is bonded integrally by the needle punching by forming the webs, and the needle punching is performed in the order of pre-needle punching, low-speed needle punching, high-speed needle punching and low-speed needle punching to uniformly bridging the surface and the inside of the formed webs and improve a binding force. At least one surface of the sheet is modified by heat treatment through hot air or a heating drum.

The present invention relates to a multilayer protective mask having antimicrobial properties, said mask comprising a body portion comprising: at least a first and a second fabric layers having random fiber configuration; a middle layer comprising a nanofiber membrane; and a third and a fourth fabric layers. The first fabric layer is disposed between the third fabric layer and the nanofiber membrane, and the second fabric layer is disposed between the fourth fabric layer and the nanofiber membrane. The first, the second, the third, and the fourth fabric layers have incorporated therein a synergistic combination of at least two metal oxide powders, comprising a mixed oxidation state oxide of a first metal and a single oxidation state oxide of a second metal, said combination having synergistic antimicrobial properties.

In the method for producing open-porous bone implants with freely accessible guide structures made from fibers, which are formed from a biocompatible metal or metal alloy, long fibers are superimposed in multiple layers, each in the form of a nonwoven, in which the fibers in each layer are arranged in a mutually preferred axial direction. Needling is carried out in at least one of the layers, by means of which individual fibers of the respective layer are aligned in an axial direction which differs by at least 60? from the preferred axial direction in which the other fibers of the layer are aligned. The superimposed layers are materially fitted to one another point by point via sinter bridges on fibers by sintering in a heating device.

Aspects herein are directed to a recyclable, asymmetrical-faced composite nonwoven textile suitable for use in apparel and other articles and methods of making the same. In example aspects, the asymmetrical-faced composite nonwoven textile includes a first face formed, at least in part from a first entangled web of fibers and an opposite second face formed, at least in part from a second entangled web of fibers. When incorporated into an article of apparel, the first face forms an outer-facing surface of the article of apparel, and the second face forms an inner-facing surface of the article of apparel. The first face includes features making it suitable to form the outer-facing surface such as resistance to abrasion, and the second face includes features making it suitable to form an inner-facing surface such as a soft hand.
