  • Patent number: 7854813
    Abstract: A method for manufacturing a nonwoven fabric, wherein a layer of nonwoven fabric is made up of a fiber mixture of at least two different types of fibers is formed. The single nonwoven fabric layer is solidified. The solidified single nonwoven fabric layer is then subjected to heat treatment subject to the condition that shrinkage of at least one of the types of fibers is activated.

  • Patent number: 7854816
    Abstract: A laminate is made by first treating two spun-bond webs formed of endless thermoplastic synthetic-resin filaments with wetting agents. Then a layer of hydrophilic fibers is applied to one of the treated spun-bond webs and then the other of the treated spun-bond webs is applied to the layer of hydrophilic fibers on the one treated spun-bond web. Finally the two treated spun-bond webs and the layer of hydrophilic fibers between them are hydrodynamically consolidated together.

  • Publication number: 20100242839
    Abstract: An apparatus for applying a treatment liquid to a web moving in a predetermined web-travel direction has an applicator element having a surface extending transverse to the direction and positioned to contact the moving web. The liquid is applied to the surface such that the liquid is transferred to the moving web where the moving web contacts the surface. A shield directly engages a portion of the surface between the web and the surface so that where the shield extends between the moving web and the surface there is generally no transfer of the liquid from the surface to the moving web. Formations on the shield conduct the liquid away from edges of the shield.

  • Patent number: 7585438
    Abstract: Method for the cleaning of spinning devices with a plurality of spinning apertures for the output of molten plastic. With the spinning device in operation, individual dirt-contaminated and/or clogged spinning apertures are closed with plugs, these plugs-consisting of at least in part of at least one oxidizable substance. The spinning device is subjected in the course of its cleaning to a pyrolysis treatment for the breakdown of residual plastic. The spinning device is subjected to an oxidative treatment, so that the oxidizable substance is oxidized.

  • Publication number: 20090152757
    Abstract: A method of making a spunbond fleece from continuous filaments wherein at least some of the filaments produced have natural crimp. The filaments are deposited in the deposition station of a conveyor creating a filament mass and the conveyor transports the filament mass toward a consolidating device. A gas stream is produced that flows along the upper surface of the filament mass in the travel direction of the filament mass.

  • Publication number: 20080220161
    Abstract: A spunbond web is made by extruding a multiplicity of hot thermoplastic filaments, passing the filaments along an upstream stretch of a path, cooling and stretching the filaments as they move along the upstream stretch of the path, and depositing the cooled and stretched filaments at a downstream end of the upstream stretch on a foraminous belt such that the filaments form a mat thereon. The belt is continuously displaced the belt so as to move the mat downstream along a downstream leg of the path. The mat on the belt, then consolidated with a high-pressure water-jet treatment, and further processed.

  • Publication number: 20080210363
    Abstract: Process of manufacturing spun-bonded fabric, using naturally crimped filaments, whereby the filaments are passed through a stretching unit and finally through a diffusor. The filaments are thereupon layered on a layering device, as crimped filaments. The layered filaments together with the layering device are passed through a solidifying device in which the filaments are solidified by means of a fluid.

  • Publication number: 20070143976
    Abstract: A fiber laminate for use as an absorbent cleaning cloth is made by first preconsolidating by calendering at least one spun-bond web of filaments and then applying at least one fiber layer of hydrophilic natural or converted cellulose fibers to the pre-consolidated spun-bond web. The two layers are then hydrodynamically consolidated into a two-layer laminate, and a surface of the hydrodynamically consolidated two-layer laminate is embossed.

  • Publication number: 20070022586
    Abstract: A voluminous fiber laminate is described, which contains one or more layers of an absorbent fibrous material, which is compacted through water needling, between at least two carrier nonwoven materials, it having areas having higher needling density and areas having lower needling density over the entire area of the fiber laminate to form a quilted structure. A device cited for this purpose is distinguished in that the water needling unit also has, in addition to nozzle strips having a large number of nozzles per unit area, nozzle strips having a lower number of nozzles, or one or more nozzle strips are dispensed with completely.
