  • Patent number: 7279441
    Abstract: A polyolefin plaque is made by hot compaction of an assembly of fibres of the oriented polymer. It has been found to be beneficial to subject the fibres to a prior crosslinking process. Hot compaction is then less temperature-sensitive and produces plaques with excellent hot strength properties. Preferably the fibres have been subjected to prior stages of irradiation and annealing, both in a non-oxidising environment, for example acetylene.

  • Patent number: 7255816
    Abstract: A method of recycling bonded fibrous materials, the method includes the steps of: providing pieces of bonded fibrous materials, the pieces having sizes that are adapted for suspension in a liquid; suspending the discrete pieces of bonded fibrous materials in a liquid; applying mechanical work to the liquid suspension of discrete pieces to generate hydraulic pressure and mechanical shear stress conditions sufficient to hydraulically fragment the bonded fibrous materials into fibers and fiber-like components; and separating substantially individual fibers and fiber-like components from the liquid. The method is used to produce recycled synthetic fibers and fiber-like materials that have at least one thread element composed of synthetic material having at least one irregular distortion generated by hydraulic fracture of the thread element to separate it from a bonded fibrous material while the bonded fibrous material is suspended in a liquid.

  • Patent number: 7211291
    Abstract: A composite having a plurality of filaments arranged in a fibrous web that is held together in a unitary structure by a domain matrix. The domain matrix comprises a plurality of matrix islands that individually connect, or bond, at least two filaments, to thereby hold the filaments in a unitary structure. Portions of the filament lengths within the unitary structure are free of matrix islands, causing the domain matrix to be discontinuous. The composite possesses a greater flexibility than coated structures. The composite may be formed into cross-plied structures. A method of making the composite also is disclosed.

  • Patent number: 7196022
    Abstract: Absorbent products and wet wipes are disclosed that are useful in reducing the amount of ammonia produced by bacteria on or near the skin or in bodily fluids such as urine. The products described herein contain an osmoregulation protector which when introduced into a bacteria-containing environment interacts with the bacteria and reduces the amount of ammonia produced by the bacteria without significantly affecting the growth rate of the bacteria. The osmoregulation protectors described herein are particularly useful in combination with adult incontinence garments where the control of odors from bacterial by-products such as ammonia is highly desirable.

  • Patent number: 7192633
    Abstract: A covering for an architectural opening, having a first layer with alternating relatively opaque stripes and relatively translucent stripes, and a second layer with alternating relatively opaque stripes and relatively translucent stripes. The first and second layers are positioned one behind the other, with the stripes substantially parallel. The first and second layers are movable relative to one another in a direction substantially perpendicular to the stripes. The covering also includes a series of parallel binder threads for attaching the first layer to the second layer. The binder threads run substantially perpendicular to the stripes, and thereby, one of the layers can be slid along the binder threads when moved relative to the other. The blind is preferred to be woven as a double-layer fabric.
