  • 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.

    Patent number: 6630046
    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.

  • 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.
