The possibilities of using thermoelectric textiles in firefighters’ turnout garment, including for powering an autonomous early warning system, are shown. The process of coaxial wet forming of fiber in the core-shell segment of the p-n junction based on the method of continuous alternating coaxial wet corkscrew is described. Polyparaphenylene terephthalamide fibers with a core-shell segment of the p-n junction were used in the experiment. The electrical properties of thermoelectric fibers, as well as the stress-strain relationships of n-segment, p-segment, and p-n segmented thermoelectric fibers, and the temperature dependence of the Seebeck coefficient are studied. It was determined that thermoelectric p-type and n-type fibers with the same number of individual fibers generated almost the same output voltage, which indicated the possibility of forming a fiber battery. A conclusion is made about the possibility of using thermoelectric fabrics based on thermoelectric aramid nanofibers for the manufacture of firefighters' combat clothing and thereby providing autonomous power to fire alarm sensors.
