Abstract
A heating/warming textile article (11) with a fabric body (13) with electrical resistance heating/warming elements (15) also contains a phase change component (17) which releases and absorbs latent heat in a cycle corresponding to ON/OFF operation of a power source (23), e.g., a battery, thus to conserve and extend useful battery life.
Claims13
A heating/warming textile article comprising:
- a fabric body;
- an electrical resistance element attached to the fabric body, the electrical resistance element capable of being electrically coupled to and uncoupled from an electrical power source to cyclically provide electrical power to the electrical resistance element for providing heating/warming of the textile article;
- and
- a phase change component associated with the fabric body and including a phase change material formulated to change phase in a temperature range of use of the textile article, to cyclically absorb and release latent heat in a manner capable of conserving use of the electrical power source;
- wherein the phase change component includes a phase change fiber that microencapsulates the phase change material.
