  • 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.

  • Patent number: 8420005
    Abstract: The present invention provides a meltblown wetlaid method for producing non-woven fabrics with anti-mildew, anti-bacteria and deodorizing capabilities from natural cellulose. The method comprises selecting wood pulp as raw material and using N-methylmorpholine N-oxide (NMMO) as dissolving solvent and 1,3-phenylene-bis 2-oxazoline (BOX) as stabilizer to form mixed cellulose mucilage as well as using modified and nano-miniaturized natural chitosan as additive for blending and dissolution to form cellulose dope. By meltblown method, the dope is extruded out of spinnerets to form filament bundle, then by ejecting mist aerosol of water, the filament bundle is coagulated with regeneration. After post treatments of water rinsing, hydro-entangled needle punching, drying, winding-up and the like having been orderly applied, then final product for nonwoven fabric of continuous filament with anti-mildew, anti-bacteria and deodorizing capabilities is produced.

  • Patent number: 8407869
    Abstract: A carpet is having a raschel fabric to the back face. The raschel fabric consists of wefts which are inlay-yarns and warps which are chain-stitched yarns. The warp consists of chain-stitched ground yarns 3a, 3b, and a pile yarn 4 which forms standing loop piles on specified courses and which is chain-stitched with the ground yarns except said specified courses. The pile yarn consists of two mono-filaments 5, 5. The two mono-filaments 5, 5 are twisted at least one time per the length of each loop pile. Cut piles are formed by mechanically cutting the each loop pile near the top thereof. The two mono-filaments in the cut pile are disjoining each other and standing with inclination at random direction on the raschel fabric. When the carpet is placed on the surface of a mat, each mono-filament which is formed on the back face of the carpet, bites into the surface of the mat. Therefore, it is prevented that the carpet is displaced.

  • Patent number: 8398752
    Abstract: A non-woven textile based filter media is produced from polyester fiber generated using recycled polyethylene terephthalate (PET) beverage bottles, and that non-woven textile based filter media is used to make an air filter. By controlling the diameters and lengths of the PET derived polyester fibers, a non-woven textile based filter media that exhibits a natural Minimum Efficiency Reporting Value (MERV) of about 8 (without requiring electrostatic treatment) and a pressure drop of 2.9 PSI or less can be achieved. A related exemplary embodiment is an air filter fabricated entirely from recycled materials, including a recycled cardboard frame, the non-woven textile based filter media made from recycled PET derived polyester fibers, and a support structure made of recycled plastic or metal wire.

  • Patent number: 8381376
    Abstract: A method of manufacturing a fibrous structure is particularly, though not exclusively, applicable to the manufacture of friction products such as preform discs. The method comprises mounting a former on a shaft. First feeds of fibrous material are spaced along the shaft and applied to the former in a direction tangential to the shaft as the shaft is rotated. A second feed is also applied to the former in a direction substantially parallel to the longitudinal axis of the shaft. The fibrous materials in the feeds overlie as the shaft rotates and the thickness of the material applied to the former increases to form the fibrous structure. Lengths of the first and/or second feeds are then inserted into the fibrous structure body in a radial direction with respect to the shaft as the shaft is rotated to interconnect the overlying layers and hold the structure together.

  • Patent number: 8366988
    Abstract: The present invention provides a “spunbond wetlaid method for producing non-woven fabrics from natural cellulose” using pulp as raw material and N-methylmorpholine N-oxide (NMMO) as solvent for dissolving into dope. Then, the dope is extruded out of a spinneret to form filament bundle by spunbond method. The dope is extruded out of a spinneret bank of grouped spinnerets to form filament bundle for further stretching process under quench condition. The filament bundle is coagulated with regeneration in a coagulating solution. The coagulated filament bundle is rapidly stretched under high pressure by an air draw-off machine. The stretched filament bundle is collected and stacked on a collecting net as web nonwoven. After post treatments of water rinsing, hydro-entangled needle punching, drying, winding-up and the like have been orderly applied then final product of nonwoven fabrics with continuous filament are produced from natural cellulose.
