Technological Innovation in Thermal Socks
Manufacturers within the Guangdong Nanhai industrial cluster are employing advanced “air-layer weaving technology” to produce thermal socks that offer both insulation and breathability. By blending Xinjiang long-staple cotton with specialized heating yarn, these socks perform effectively in temperatures as low as -15°C. Supported by OEM/ODM services, suppliers provide sampling within seven days—allowing customization of yarn composition, thickness, and logo embroidery. Minimum order quantities start at 500 pairs, with unit prices reported to be 15–20% more competitive than those of Southeast Asian counterparts.
