Attorney, Agent or FirmInternational ClassH05B 003/34AbstractA fabric article that generates heat upon application of electrical power is formed, for example, by joining stitch and loop yarns to form a fabric body, with the loop yarn overlaying the stitch yarn at a technical face and forming loops at a technical back of the fabric body. An electrical resistance heating element, e.g., in the form of a conductive yarn, is incorporated into the fabric body at symmetrical and/or asymmetrical spaced-apart intervals as the stitch yarn, the electrical resistance heating elements extending between opposite edge regions of the fabric and conductor elements, e.g. located along edge regions, connect the electrical resistance heating elements to a source of electrical power. The technical face and/or the technical back of the fabric body may have fleece formed by finishing in a manner to avoid damage to electrical conductance of the electrical resistance heating elements. Preferably, the conductive yarn has a core of insulating material, an electrical resistance-heating element about the core, and a sheath material surrounding the electrical resistance heating element and core.Field of SearchResistive element interwoven with fabric supportCloth or other fabric Apparel Bed covering (e.g., blanket) Static structure (e.g., building pavement, etc.) Chair, bed, or other body-supporting means Body-supported (e.g., human body) Flexible or resilient (e.g., warming pad) Flexible MESH, WOVEN, OR BRAIDED RESISTANCE ELEMENT Incorporating unknit or fleece-type materials Incorporating unknit or fleece-type materials Incorporating unknit or fleece-type materials FABRICS OR ARTICLES Articles Garments Reinforced Incorporated unknitted materials Fleece or pile type Warp With crochet stitch Fleece or pile type Warp Materials Resistor making Heater type UPHOLSTERED ARTICLE MAKING Method | |
