Russian start-up ArcticTex, has been working in cooperation with Russian sportswear manufacturer Sportego on the design of new apparel with built-in heating systems based on printed carbon nanotubes. A pilot jacket created has already been tested during an ascent of Mount Elbrus, the highest mountain in Russia. Participants in the expedition evaluated the heating-up speed, evenness and surface area of the fabric at different temperatures, its battery life, and abrasion resistance.

The heating material was also tested together with the St. Petersburg State University of Industrial Technology and Design (SPbSUITD). This research has shown that the ArcticTex fabric warms up to operating temperature in just 40 seconds, ensuring heat distribution across the entire surface of the fabric. The material’s fast heating ability makes it possible to halve the weight of the finished product by reducing the thickness of the insulation.

The printed carbon nanotubes can make the entire fabric a heating element in its own right, providing more surface area for uniform heating, or localised heating zones can be strategically structured within designs. The fabric is heated from a portable power source, with enough charge for 4-6 hours of continuous operation. The maximum heating temperature is 45ºC, providing comfort and safety for the user.

“The properties of our warming fabrics open up the possibility of producing clothing with climate control and thermoregulation while keeping the product light and allowing greater freedom of movement,” said Olga Moskaluk, head of the ArcticTex start-up “These are the basic requirements of clothing for mountaineering and active sports in cold weather conditions.”
