Resistive Heating Metal Fibre Fabrics
topic
Resistive heating textile fabrics incorporate metal fibre yarns at defined spacing and linear resistance values to achieve target power density of 10 to 100 watts per square metre when connected to low-voltage direct current power supply, with heat distribution uniformity quantified by infrared thermography and maximum surface temperature controlled by positive temperature coefficient fibre characteristics or external thermostat circuit.
Role
Enables flexible conformal heated textile products including electrically heated outdoor garments, car seat heating elements, medical warming blankets, and heated floor covering underlays where the combination of flexible fabric form factor, uniform heat distribution, and low-voltage safe operation from battery or vehicle power provides user comfort and therapeutic benefit.
