Thermolite Base is a kind of insulation fiber developed by Du Pont (now Invista), which received great inspiration from polar bears when they studied the insulation fiber. They came up with the idea to create hollow fibers, which can contain warm air inside the fiber and exclude cold air outside. The fabrics made of it have permanent insulation function with other excellent features like lightness, air permeability, flexibility, comfort, no shrinkage, no wrinkle, and no fade.
100% Thermolite Based yarn count range is between 20/1NE~40/1NE. Due to restrictions from Invista!|s label, fabrics are usually cross-woven in 100% Thermolite Base yarn and other yarns. Mostly for circular knitted fabrics, such as insulation underwear, high collar sportswear, various outerwear and sleeping bag linings.
