Abstract: Nonwoven fibrous webs including randomly oriented discrete fibers defining a multiplicity of non-hollow projections extending from a major surface of the nonwoven fibrous web (as considered without the projections), and a plurality of substantially planar land areas formed between each adjoining projection in a plane defined by and substantially parallel with the major surface. In some exemplary embodiments, the randomly oriented discrete fibers include multi-component fibers having at least a first region having a first melting temperature and a second region having a second melting temperature, wherein the first melting temperature is less than the second melting temperature. At least a portion of the oriented discrete fibers are bonded together at a plurality of intersection points with the first region of the multi-component fibers. In certain embodiments, the patterned air-laid nonwoven fibrous webs include particulates.

Abstract: Porous supported articles and methods of making are disclosed. Multicomponent polymeric fibers are introduced into a forming chamber and are infilled at least into the interior void spaces of a support web. At least some of the infilled multicomponent component fibers are self-bonded to each other to form a porous web that is embedded within the support web. The porous embedded web may contain particles that are bonded to the multicomponent fibers of the web. The optional particles in the porous embedded web may be e.g. abrasive, absorbent, etc.

Abstract: Porous multilayer articles and methods of making are disclosed. Multicomponent polymeric fibers are introduced into a forming chamber and are deposited onto a first porous substrate. The multicomponent fibers are then bonded to each other to form a porous coherent web, and the porous coherent web is bonded to the first porous substrate, so as to form a porous multilayer article. The porous coherent web contains particles that are bonded to the multicomponent fibers of the web. The particles in the porous coherent web may be e.g. abrasive, absorbent, etc.

Abstract: A thermo-bonded non-woven fibrous wipe material is described, in which at least some of the fibres are regenerated plant-protein fibres. Also described is a method of making such a thermo-bonded fibrous non-woven wipe material, comprising the steps of forming a non-woven web of fibres, the web containing heat-sensitive material, and applying heat to the web to melt the heat-sensitive material and thereby cause fibres in the web to be bonded together; wherein at least some of the fibres are regenerated plant-protein fibres. The regenerated plant-protein fibres may comprise soybean protein.

Abstract: A scouring material comprises a three-dimensional non-woven web (3) of entangled fibres (5) bonded to one another at mutual contact points (7). The fibres comprise natural vegetable fibres in an amount of at least 50% by weight, and crimped synthetic fibres in an amount of at least 5% by weight. The fibres, throughout the web, have a substantially continuous coating of binder resin; and the web of bonded fibres has a maximum density of 60 kg/m3. A method of making the scouring material comprises the steps of: forming a three-dimensional non-woven web of entangled fibres; roll-coating the web with a binder resin; and curing the binder resin to form the scouring material.
