Carbon fabric (CF) is one type of high performance carbon fibers with a carbon content of more than 95%, which possesses a series of compelling properties, such as high specific strength, high thermal stability, excellent electrical conductivity, and superior fatigue resistance. CF can be an ideal material choice to serve as a favorable electrical heating element in a heater with distinctive features of better air-permeability, flexibility and Wear ability. Woolen yarn is also widely used as a material for heating products due to its good thermal insulation effects.
Currently, most heating products to address the warmth retention issues are fabricated with solar energy heating materials, phase change materials, chemical energy heating materials, and electric heating materials to store or generate heat.
The electrothermal fabric could achieve a steady-state temperature of 75.4 °C in 30 s under 10 V voltage. designed cotton fabrics coated with graphene/ polyurethane composite using pad-dry-cure process. This process enhanced the far-infrared emissivity up to 0.911 and the obtained fabrics reached the destination temperature of 100 °C in 5 min 58 s.
It is highly desirable to explore more facile and versatile techniques to develop highly flexible and efficient infrared radiation heating textiles with advanced material selection and rational structure design.
