  • Patent number: 5192600
    Abstract: A stitchbonded comfort fabric is disclosed that is absorbent, durable and quick-drying. The fabric is made up of an absorbent, evaporation-reservoir layer and a nonabsorbent, transport layer. The evaporation-reservoir layer comprises a nonwoven web that is stitched with at least one bulkable stitching yarn. The transport layer weighs at least 10 gms/sq m and can be formed from a network of fibrous stitching yarns that do not significantly absorb water and do not exhibit stitching gaps wider than 3 mm. The resulting fabric has a basis weight of between 20 and 120 gm/sq. m, a bulk of at least 10 cc/gm and the capability of absorbing at least 5 times its weight in water. The fabric is useful in intimate apparel, underwear, swimwear, sports shirting, headbands and comfort linings.

  • Patent number: 5190694
    Abstract: A carrier strip in the form of a nonwoven, woven or knitted fabric made from natural and/or synthetic fibres, for use with foaming detergents, is loaded with antifoam active chemical substances. As a result of its compact packaging and ease of handling, no antifoam substances are released prior to use, prior to contact between the carrier and detergents. To this end, the folded carrier is packed in a sealed water soluble film and deploys its total surface only on contact with the detergents.

  • Patent number: 5147721
    Abstract: A glass matrix/ceramic fiber reinforcement composite is prepared from a yarn formed by spinning glass fiber and ceramic fibers lengths together, to form a bicomponent yarn. The yarn is weavable and spinnable, and accordingly may be prepared in fabric forms, or in windings, of predetermined shape. The precursor is melted by heating to the temperature of the melting point of glass, which fused the glass into a continuous matrix, surrounding the ceramic reinforcement.

  • Patent number: 5147715
    Abstract: Applicant's invention relates to a rectangular shaped pad composed of a heat retentive, hydrophobic textile material encapsulating a heat retentive vinyl-like material together performing a desiccating function by wicking water away from wet drying clothes onto the adsorptive surface of the textile material and facilitating the drying mechanism of a clothes dryer by raising the ambient temperature in the dryer drum which expedites water vaporization for removal from the dryer drum by the exhaust vent. The rectangular shape and stabilizing units further coordinate to maintain the structural integrity of the entire drier pad unit by preventing the pad from collapsing-in upon itself which maximizes the surface area of the pad which communicates with the drying clothes, thus decreasing the standard drying time required for removing water vapor from the dryer drum and thereby conserving valuable energy.
