Evaluation of Heating Inserts in Active Protective Clothing for Mountain Rescuers—Preliminary Tests

Rescue operations in mountain areas, lasting many hours, pose a mental and physical burden on the rescuer’s body. In addition, they cause thermal discomfort associated with variable energy expenditures high variability of weather conditions. One solutions for improving comfort work rescuers is clothing an active heating function. This paper discusses technology manufacturing flexible inserts steel thread as element. order to assess durability safety applied inserts, were subjected simulated conditions use. Multiple washing (25 cycles) bending (9000 well exposure artificial acidic sweat did not significant change electrical power resistance inserts. effectiveness tested within system fabrics “artificial skin model”. Supplying insert voltage 4 V increased fabric system, incorporating by approx. 40%. Due their flexibility, durability, efficiency, developed are major step towards development heated clothing.
