Claims
- 1. A method of forming an electric heating/warming composite fabric article, comprising:providing a fabric layer having an inner surface and an outer surface and a barrier layer resistant to through-passage of air and having an inner surface and an outer surface, joining the inner surface of the fabric layer to the outer surface of the barrier layer, applying an electricity-conducting paste upon the inner surface of the barrier layer in a predetermined pattern of an electric circuit, and curing the electricity-conducting paste to form an electric heating/warming element in the form of a flexible, electricity-conducting film defining an electric circuit upon the inner surface of the barrier layer, the electric heating/warming element being adapted for connection to a power source, thereby to generate heating/warming, and said flexible, electricity-conducting, heat-generating film comprising synthetic resin material and comprising, in electrical current flow direction, a first circuit filament region adapted to generate heat at a first rate and a second circuit filament region adapted to generate heat at a second rate, said first rate being different from said second rate.
- 2. A method of forming an electric heating/warming composite fabric article, comprising:providing a barrier layer resistant to through-passage of air and having an inner surface and an outer surface, applying an electricity-conducting paste upon the inner surface of the barrier layer in a predetermined pattern of an electric circuit, curing the electricity-conducting paste to form an electric heating/warming element in the form of a flexible, electricity-conducting film defining an electric circuit upon the inner surface of the barrier layer, providing a fabric layer having an inner surface and an outer surface, and joining the inner surface of the fabric layer to the outer surface of the barrier layer, the electric heating/warming element being adapted for connection to a power source, thereby to generate heating/warming, and said flexible, electricity-conducting, heat-generating film comprising synthetic resin material and comprising, in electrical current flow direction, a first circuit filament region adapted to generate heat at a first rate and a second circuit filament region adapted to generate heat at a second rate, said first rate being different from said second rate.
- 3. A method of forming an electric heating/warming composite fabric article, comprising:providing a fabric layer having an inner surface and an outer surface, applying an electricity-conducting paste upon the inner surface of the fabric layer in a predetermined pattern of an electric circuit, and curing the electricity-conducting paste to form an electric heating/warming element in the form of a flexible, electricity-conducting film defining an electric circuit upon the inner surface of the barrier layer, the electric heating/warming element being adapted for connection to a power source, thereby to generate heating/warming, and said flexible, electricity-conducting, heat-generating film comprising synthetic resin material and comprising, in electrical current flow direction, a first circuit filament region adapted to generate heat at a first rate and a second circuit filament region adapted to generate heat at a second rate, said first rate being different from said second rate.
- 4. The method of claim 3, further comprising the steps of:providing a barrier layer resistant to through-passage of air and having an inner surface and an outer surface, and positioning the outer surface of the barrier layer at least adjacent to the inner surface of the fabric layer, to overlay at least a portion of the electric heating/warming element.
- 5. The method of claim 1, 2 or 3, wherein, during the step of curing, the electricity-conducting paste is cured to form a stretchable film defining the electric circuit.
- 6. The method of claim 1, 2, 3 or 4, comprising the further step of incorporating the electric heating/warming composite fabric article into articles of apparel.
- 7. The method of claim 1, 2, 3 or 4, comprising the further step of connecting the electric heating/warming element to a power source, thereby to generate heating/warming.
- 8. The method of claim 1, 2, 3 or 4, comprising the further step of incorporating the electric heating/warming composite fabric article into home furnishings textile articles.
- 9. The method of claim 6 wherein the articles of apparel include at least one of the following: jackets, sweaters, hats, gloves, shirts, pants, socks, boots, and shoes.
- 10. The method of claim 8 wherein the home furnishings textile articles include at least one of the following: blankets, throws and seat warmers.
