  • Composite textile material
    Patent number: 6806214
    Abstract: A composite textile fabric includes a composite layer of a hydrophobic material and a layer of a hydrophilic material knitted or otherwise formed together. The composite layer has an upper surface of small exposed areas of the hydrophilic material covering a total area about 25% of the overall area of the upper surface. The composite layer provides one way liquid transport for moisture, extending from the upper surface towards a lower surface of the composite layer.
    Type: Grant

    Date of Patent: October 19, 2004
    Assignee: The Hong Kong Polytechnic University

  • Moisture management of textiles
    Patent number: 6499338
    Abstract: Moisture management indexes are determined for a textile sandwiched between two plates. Electrical conductors arranged in concentric opposing pairs are used to measure changes in electrical resistance of the fabric. A quantity of water (or other chosen liquid) is poured down a guide pipe and changes of resistance measured against time. From this data, specific indexes are determined, in a repeatable fashion, and used for determining moisture management characteristics of the fabric.

  • Composite textile material
    Publication number: 20020094740
    Abstract: A composite textile fabric includes a layer 10 formed of hydrophobic 10A and hydrophilic material 10B knitted or otherwise formed together. The layer 10 is formed such that an upper surface consists of a plurality of small exposed areas of the hydrophilic material making up in total area about 25% of the overall area of the upper surface. The layer 10 acts as a one way liquid transport for moisture, extending away from the upper surface towards a lower surface of the layer 10.

  • Moisture management of textiles
    Publication number: 20020043100
    Abstract: Moisturing management indexes are determined for a textile sandwiched between two plates. Electrical conductors arranged in concentric opposing pairs are used to measure changes in electrical resistance of the fabric. A quantity of water (or other chosen liquid) is poured down a guide pipe and changes of resistance measured against time. From this data, specific indexes are determined, in a repeatable fashion, and used for determining moisture management characteristics of the fabric.
