The present invention concerns a process for preparing a microfibrous multilayer composite material comprising: 1) realizing a non-woven microfibrous semi-finished product made up of microfibres of one or more polymers dispersed in a polyurethane matrix (semi-finished product IE); 2) cutting the semi-finished product lengthwise into two layers; 3) buffing at least one layer on one side (side N) so as to extract the microfibres and form the nap, thereby obtaining a semi-finished raw product; 4) cutting at least one semi-finished raw product lengthwise parallel to the surfaces, producing an non-woven intermediate product, containing the buffed side (side N) and a waste layer (containing the side that has not been buffedside S); 5) coupling the non-woven intermediate product (on the side opposite side N) to a fabric made of polyethylene terephthalate fibres by means of the application of a thermoplastic polyurethane adhesive that can be cross-linked between the non-woven intermediate product and the fabric; 6) submitting the multilayer composite material to a jet dyeing process. The invention also concerns a multilayer composite material that can be obtained by the process of the invention and the use thereof for covering the internal side of roofs or headliners of vehicles and for covering furnishing elements.

The present invention refers to a process for the preparation of a non-woven microfibrous suede-like synthetic fabric that does not require the use of organic solvents and that makes it possible to obtain a finished product offering a good hand, excellent resistance to yellowing and high durability. It comprises needle-punching a felt of sea/island fibers, (a) impregnation with hot aqueous solution of PVOH having a degree of saponification of at least 94% or (b) impregnation with hot water followed by impregnation with cold PUR, removing the sea component, impregnating with PUR, coagulating the PUR, removing the PVOH, grinding the surface, dyeing and splitting in two sheets.

A process and apparatus is used for making a fibrous nonwoven web with uniform, directionally-oriented projections by depositing fibrous material onto a first forming surface with holes positioned above a second forming surface with both forming surfaces traveling at different speeds to one another. As the fibers are deposited onto the first forming surface, a portion of the fibers are drawn down into the holes of the first forming surface forming the projections which contact the second forming surface. Due to the speed differential between the two forming surfaces the projections are uniformly skewed in the same direction. The resultant material is particularly suited for use as a wiping material which can be more abrasive in one direction but which is softer to the touch when wiped in the opposite direction thus making it a dual purpose material.

The invention relates to the use of a fleece composed of plastic filaments, in particular made of a thermoplastic, as a sustained-released system or as a storage system for at least one active substance, in particular for at least one active liquid. The filaments are spun using a spinneret, and the plastic material of the filaments is foamed so that pores are formed at least on the surface or in surface regions of the filaments and at least some of the pores are pores that are open outward, and at least some of the open pores are filled with the active substance, in particular with the active liquid.

A woven brushed elastic fabric includes a fabric blank and a plurality of yarn segments. The fabric blank is formed by interweaving a plurality of first yarns and composite yarns. Each composite yarn is composed of a second yarn and an elastic yarn. The second yarn is wound around the elastic yarn. The fabric blank has a first side, and a second side opposite to the first side and formed with a plurality of yarn loops. The yarn loops are formed by the interweaving of the first yarns and the composite yarns in a skip manner along a first direction or a second direction transverse to the first direction. The yarn segments are formed on the second side of the fabric blank by breaking at least some of the yarn loops.

The invention refers to a process for the preparation of a microfibrous non-woven fabric based on polyester or polyamide microfibers immersed in a polyurethane matrix, and having a thickness equal to or less than 0.65 mm, a flat or slightly mottled appearance and a nap length of less than 350 m. The non-woven fabric is used for the preparation of coverings for consumer goods, particularly for the preparation of covers and cases for electronic products.

A disposable absorbent article is disclosed herein. The disposable absorbent article includes a topsheet forming a portion of a wearer-facing surface, the topsheet being a composite or laminate structure having a first side and an opposing second side, the composite or laminate structure having a first layer and a second layer, wherein the first layer is a nonwoven and the second layer is a film, the topsheet having a pair of edge regions at least partially disposed on the wings and a central region disposed inboard of the pair of edge regions, wherein the pair of edge regions include a first plurality of discontinuities and the central region comprises a second plurality of discontinuities, wherein the first plurality of discontinuities and the second plurality of discontinuities are different; a backsheet forming a portion of the garment-facing surface; and an absorbent core disposed between the topsheet and the backsheet.

Disclosed is a structure of a matrix, reinforced with a plurality of polymeric fibers protruding from at least a portion of the structure surface, the fibers being capable of endowing (attributing) the at least a portion of the surfacewith biological or chemical resistance. In some embodiments, the polymeric fibers, as further discussed hereinbelow, contain or are coated with at least one biological or chemical agent which further contributes to the endowment of biological or chemical resistance.

An absorbent article having a topsheet, a backsheet, and an absorbent core between the topsheet and backsheet. The topsheet has a central region, a first end intermediate region, a first end region, a second end intermediate region, a second end region, an edge region, and an intermediate edge region. The central region, first end intermediate region, first end region, second end intermediate region, and second end region are disposed on a line generally parallel to the longitudinal centerline. The central region, intermediate edge region, and edge region are disposed on a line generally parallel to the transverse centerline. The central region texture, first end intermediate region texture, first end region texture, second end intermediate region texture, and second end region texture differ from one another. The central region texture, intermediate edge region texture, and edge region texture differ from one another.
