  • Publication number: 20150044928
    Abstract: A non-woven fabric (1) that is modified with activated carbon is needled on an elastic or inelastic textile sheet material (2), preferably a woven fabric or a knitted fabric. With this method, it is achieved that the strength of the textile sheet material (2) can be imparted to a non-woven fabric (1) that is otherwise not tear-resistant, whereby the adsorption properties of the activated carbon that are necessary in protective textiles are completely retained. During needling, the elastic or inelastic textile sheet material (2) is stretched or kept stretched, and stress is relieved after needling. The effect that is thus achieved is that the non-woven fabric (1) does not tear when the textile good or the molded part is stretched again, since the non-woven fabric then is stretched out from a compressed initial state.

    Abstract: Fibers can include a polypropylene composition, which can include a metallocene random copolymer of propylene and a comonomer that is an alpha-olefin different from propylene. The metallocene random copolymer can have a comonomer content of from 1.2 wt % to 1.8 wt %, a molecular weight distribution of at least 1.0 and of at most 4.0 obtained without thermal or chemical degradation, and a melting temperature Tmelt of at most 140° C. A nonwoven can include the fibers, and a laminate can include the nonwoven. The fibers can be produced by polymerizing the propylene and comonomer in presence of a metallocene-based polymerization catalyst to obtain the metallocene random copolymer. The polypropylene composition can be melt-extruded to obtain a molten polypropylene stream, which can be extruded from capillaries of a spinneret to obtain filaments. A diameter of the filaments can be rapidly reduced to obtain a final diameter.

  • Patent number: 8025751
    Abstract: The present invention concerns a process for forming a wearable and functional fabric from a composite material comprising a nonwoven face layer containing a plurality of fibers, and at least one thermoplastic binder layer disposed underneath. The fibers are initially arranged in a generally planar web and subsequently needlepunched through at least one binder layer. The fiber layers can also be placed on both sides of one or more centrally-located binder layers, and further reinforced with scrims. In an innovative aspect of the invention, the composite is heated under low and uniform pressure to remove thermal stresses, resulting in at a least one relatively smooth face that can be coated to form a wearable fabric, e.g., artificial leather, odor absorbing fabric, and the like.

  • Patent number: 7976655
    Abstract: Discarded or recycled carpets or other textiles can be converted into wood-like materials, in sheets comparable to plywood. The carpets or textiles are shredded, combed, and layered across a conveyor to form a low-density mat, which is compressed and needle-punched to create a cohesive but flexible mat. An adhesive is applied to at least one and preferably two or more mats, by an applicator that spreads a liquid prepolymer onto one or more surfaces of the mat(s). The mat(s) travel through a press while the adhesive cures and hardens, and the use of foaming adhesives can ensure uniform permeation through dense fiber mats. The hardened sheets can be sawed, nailed, and otherwise handled like wood, and are strong, durable, and highly resistant to damage by water or insects.

  • Patent number: 7972985
    Abstract: A nonwoven fabric 10 has a first layer 1 containing crimped fibers 11. In the layer 1, the crimped fibers gather in parts to form a large number of fiber clusters 12 that are distributed all over the layer 1. The clusters 12 interconnect to each other to form a network structure in the layer 1. The nonwoven fabric 10 further has another fiber layer as a second layer 2 disposed on a side of the first layer 1. The two layers are partly joined at a large number of joints 3. The second layer 2 protrudes outwardly between the joints 3 to form a large number of protrusions 20.

  • Patent number: 7947613
    Abstract: The present invention is directed to a low-density substrate, which has an optimized pore volume distribution. The optimized pore volume distribution allows the substrate to hold at least 50 percent of its cumulative volume within pores with a radius size of about 110 to 250 microns. The optimized pore volume distribution can also be characterized by having a dry fibrous web that absorbs less than 20 percent of the cumulative volume of the fibrous web at a pore radius of 75 microns. The optimized pore volume distribution of the substrate enables it to controllably release a fluid composition effectively onto a surface. The basis weight of the substrate is about 80 to 20 gsm and the density of the substrate is below 0.1 g/cc. The substrate may be a pre-loaded wipe, which is either moistened by a consumer prior to use or moistened prior to packaging. The composition loaded onto the substrate may contain dry and/or liquid compositions preferably for cleaning hard or soft surfaces.
