Abstract

A textile made at least in part with conductive yarns for the purpose of generating heat from an electrical power source. The textile has conducting yarns, or “heaters”, with conductivity and spacing tailored to the electrical source to be used and the heat to be generated. The heater yarns have a positive temperature coefficient whereby the resistance of the yarn increases with an increase in temperature and decreases with a decrease in temperature. “Leads”, such as conductive yarns, can be used to supply electricity to the heater yarns. A coating to the textile can electrically insulate the textile as well as provide protection to the textile during activities such as laundering or use.

Claims

1. A thermal textile comprising:

at least one non-conducting yarns;

at least one positive temperature coefficient (PTC) heating yarn;

said non-conductive yarn and said PTC heating yarn being combined into a heating fabric.

2. The thermal textile according to claim 1, wherein said heating fabric is a woven fabric.

3. The thermal textile according to claim 1, wherein said heating fabric is a knitted fabric.

4. The thermal textile according to claim 3, wherein said heating yarn forms loops of said knitted fabric.

5. The thermal textile according to claim 3, wherein said heating yarn is laid into loops of said non-conductive yarn.

6. The thermal textile according to claim 1, further including at least one conductive lead electrically connecting to said PTC yarn.

7. The thermal textile according to claim 6, wherein said lead comprises a conductive yarn and wherein said conductive yarn forms loops of said knitted fabric.

8. The thermal textile according to claim 6, wherein said lead is laid into loops of said non-conductive yarn.
