  • Publication number: 20030077430
    Abstract: A nonwoven laminate material for mechanical closure systems, method for its production, and its use. The multi-layer nonwoven fabric laminate material has at least one layer of a polyolefin endless filament nonwoven fabric having a maximum tensile strength in the machine running direction that is at least as great as crosswise to that direction, and made up essentially of fibers having a titer of less than 4.5 dtex, as well as a second layer of a nonwoven fabric that is bonded to the first layer, which includes a sheet of crimped staple fibers made of polyolefins, and whose crimped fibers are coarser than the fibers of the nonwoven fabric of the first layer. The at least two nonwoven fabric layers are bonded to one another at the common interface by bonding in the form of a pre-determined pattern. With this laminate, it is possible to produce diapers that are also suitable for adult incontinence patients, which have a mechanical closure system, e.g., a Velcro™ closure.

  • Publication number: 20030059587
    Abstract: A composite material, including at least one nonwoven fabric and a reinforcing material, thermally connected to it, situated in the form of regularly recurring patterns, which is derived from sheeting made of thermoplastic material. The new composite material may be used, for example, as an operating room coat, a textile outer material for one-time use, as a belt or in absorbent products, such as diapers or feminine hygiene products.

  • Patent number: 5972427
    Abstract: An adsorbent, supple, filter fabric composed of an air-permeable, supple, textile, carrier material having adsorbent particles fixed on it by means of a thermoplastic binding agent. The adsorbent particles are coated on their surface with binding-agent particles which are set apart from each other. The average diameter of the binding-agent particles is smaller than that of the adsorbent particles. The adsorbent particles are also bonded to each other by binding-agent particles. The coating of the carrier material with adsorbent material is over 200 g/m.sup.2. The fabric has a total thickness of 0.5 to 5 mm, and its suppleness permits a bending radius of not more than 5 mm able to be carried out free of destruction. The filter fabric is manufactured by first mixing absorbent and binding-agent particles while adding water.

  • Patent number: 5665148
    Abstract: An adsorption air filter has a self-supporting shaped structure of adsorber particles of regular or irregular form, which are joined to one another by binder particles also of regular or irregular form. The melting range of the binder particles is less than that of the adsorber particles, and the binder particles are smaller than the adsorber particles. The adsorber particles have an average size of 100 to 7000 .mu.m. The three-dimensional structure of the air filter has substantially repeating units of one adsorber particle and one binder particle, without the presence of agglomerates. The binder must not spread over the adsorber surface below 100.degree. C. In the production method, adsorber and binder particles are mixed with water and heated in a closed mold under pressure; the water is then driven off and the shaped element is allowed to cool.

  • Patent number: 5387382
    Abstract: In a process for manufacturing an interior fitted part for motor vehicles, such as an inside roof lining for automobiles, a staple-fiber formed fabric of a drawn polyethylene terephthalate matrix component and of a binding component is subjected at least once during the process to an annealing process, which increases the thermal stability of the fitted part. Also disclosed is a fitted part manufactured by this method.
