  • Airbag cover
    Patent number: 7065844
    Abstract: There is described a process for producing a cover for a side airbag, which comprises first producing a polyester web, preconsolidating this web by needling and end-consolidating and fully shrinking the thus preconsolidated web by means of an embossing calender, making the thus consolidated and fully shrunk web up into a cover and providing the cover with a predetermined breaking site to tear open the cover in the event of a collision. The process is simple to carry out and leads to inexpensive covers having improved properties.

  • Wall and floor coverings
    Publication number: 20040013884
    Abstract: The present invention provides wall and floor coverings based on a carrier coated with one or more layers. The carrier includes a fiberglass containing mat consolidated with a binder, a non-woven made of organic synthetic fibers bonded with the fiberglass containing mat by needling. Part of the organic fibers penetrate through the fiberglass mat, and one or more layers coated on a glass fiber side of said carrier, opposite the non-woven synthetic mat.

  • Battery separators
    Publication number: 20030082980
    Abstract: A battery separator is described that comprises a nonwoven, pre-strengthened by needling and calibrated with a calender, which is final-strengthened with an acid-resistant binder. The battery separators have a uniform thickness, are not hairy, and can be used in a versatile manner, in particular also for tubular pockets.

  • Hydrodynamically bounded carrier webs and use thereof
    Patent number: 6412154
    Abstract: The present invention provides a method for the production of bounded non-wovens carriers. The method includes providing a glass staple fiber containing non-woven which is pre-consolidated with a binder. The glass staple fiber non-woven is placed adjacent to one or more non-wovens of synthetic fibers and hydro-dynamically needling at a water beam pressure in the range of 100 to 400 bar.

  • Laminate
    Patent number: 5017426
    Abstract: A laminate which, when used as a carrier web for roofing and sealing sheets, shows good flammability properties combined with improved mechanical properties and which comprises a layer of synthetic fibers and a layer of mineral fibers is obtained by needling two preconsolidated fiber webs, of which one comprises synthetic fibers and the other mineral fibers. The needling produces a strong positive join of the two webs, as a result of which the tendency for the two layers to delaminate under extreme thermomechanical conditions is avoided.

  • Laminate
    Patent number: 4755423
    Abstract: Laminates, which are composed of a preconsolidated synthetic fiber web and a preconsolidated mineral fiber web, which are bonded to each other by needling, are improved in respect of their dimensional stability, in particular in the transverse direction, when the preconsolidated mineral fiber wet contains reinforcing yarns of a mineral material and extending in the longitudinal direction.They are preferably used as carrier web for roofing and sealing webs.

  • Bituminized roof sheet
    Patent number: 4287248
    Abstract: The flame resistance of a bituminized roof sheet consisting of a reinforced fleece, a metal foil and bitumen is improved substantially by applying a metal foil to one face. A rupture of the metal foil in the case of stress due to elongation is prevented by wrinkling it. The elongation reserve thus obtained is in the range of from 2 to 35%.

  • Bituminized roof sheet
    Patent number: 3967032
    Abstract: A bituminized roof sheet has particular dimensional stability and strength when containing a spun fleece of polyester filaments reinforced in a quite special manner as carrier. The roof sheet has the following properties:A. a tensile strength of from about 30 to 100 kp/5 cm,B. an elongation at break of from about 20 to 60 %,C. an elastic strain of from about 1 to 5 %,D. a tear propagating strength of from about 2 to 8 kp,E. a nail plucking resistance of from about 13 to 30 kp, andF. a flexural strength of more than 5000 cycles.
