Graphene Heating Sheet for Ski Socks

This product is specially designed for high-quality cold-weather footwear, featuring an innovative design that combines revolutionary two-dimensional material technology with functional fabrics. It is particularly suitable for integration into ski socks. The material is made from a blend of cotton, nylon, and elastic fibers, providing a soft and breathable base that can adapt to foot movements. The cotton part ensures a comfortable skin contact, the nylon enhances wear resistance, and the elastic fibers enable the heating element to stretch up to 200% – maintaining conductivity during dynamic activities such as skiing or snowboarding. Through knitting technology, a seamless, 0.1-millimeter-thick structure is formed, making it invisible in the socks and compatible with the tightest boots.

This graphene heating element takes advantage of the material’s outstanding thermal conductivity (5300 watts/meter-Kelvin), evenly distributing heat on the foot, with the heating time reaching up to 45 seconds, achieving a temperature of 40 to 55 degrees Celsius. The single-atom-thick graphene layer can evenly dissipate heat without hotspots, and it saves 50% of power consumption compared to traditional alloy wires. The heating duration ranges from 3 to 11 hours (depending on the voltage), and this sheet is compatible with batteries ranging from 3.7 volts to 7.4 volts, balancing safety and energy efficiency. This fabric has undergone copper ion antibacterial treatment to prevent odor production, and its breathable knitted structure can absorb moisture, keeping the feet dry during high-intensity use.
