The present invention relates to a non-woven fabric for a non-woven air filtering substrate and an ADL substrate of fibre-based three-dimensional multi-layer structure, comprising at least 4 layers arranged one above another, arranged securely, wherein there is a first, upper layer in contact with the flow to be treated, which comprises fibres of a fineness ranging from 6 to 20 dtex and lengths ranging from 32 to 80 mm, and wherein the remaining layers comprise fibres of a fineness ranging from 0.6 to 10 dtex and lengths ranging from 12 to 64 mm. The present invention also relates to a method for producing the non-woven fabric that is the subject matter of the invention and also to the use thereof for preparing sanitary products or filters.

A non-woven material including a base layer and one or more fiber cap layer. In example embodiments, the fiber cap layer can be (1) used as an adhesive layer to bond the base layer to another material, (2) molded in order to create a smooth film surface that reduces ice, mud and snow buildup in the automotive part, (3) molded to increase stability and reduce sagging in the automotive part, or (4) molded into an air flow resistant layer to increase sound absorption properties. The non-woven material can be heat-resistant, flame-resistant, water-resistant, and/or recyclable.

A method of manufacturing stab-resistant fabric using water punching is provided. Aramid fabric and nonwoven aramid fabric are combined through water punching, thereby enhancing activities by ensuring flexibility and stab-resistance performance, and the method is an aramid composite fabric manufacturing method which performs water punching with pressure of 50 to 250 bar when the water punching is performed.

A method for manufacturing a piece of interior equipment of an automotive vehicle includes: obtaining a first web of fibers on a conveyor, the first web including a first layer of fibers forming a sole, and a second layer of fibers intended to form a velvet; depositing a second web of fibers and obtaining an assembly; needling the assembly; heating the needled assembly to a heating temperature, and obtaining a coating; and thermoforming the coating and a lower portion at a forming temperature in order to obtain the piece. The second web has continuous fibers with a single component having a melting temperature, the assembly further including a binding layer deposited on the sole of the first web, the binding layer in majority including at least one thermoplastic polymer having a melting temperature greater than the forming temperature and less than the melting temperature of the single component.

A surface covering element can have a rigid core. The rigid core can include at least one densified fiber batt. The rigid core can have a first surface and an opposed second surface that are spaced apart along a first axis. The rigid core can have a plurality of edges that define a periphery of the rigid core. The plurality of edges can include at least a first edge and an opposed second edge that are spaced along a second axis that is perpendicular to the first axis. The first edge can include a tongue, and the second edge can define a groove.

A composite nonwoven sheet material includes pulp fibers, a reinforcement material and microfibers. The sheet material has one pulp-enriched first outer layer and one microfiber-enriched second outer layer, the reinforcement material is thereby interposed between the pulp-enriched first outer layer and the microfiber-enriched second outer layer and the pulp fibers and the microfibers penetrate the reinforcement material. Also disclosed is a process of producing such composite nonwoven sheet material and the use of such composite nonwoven sheet material.
