The main material of ice silk is viscose fiber, which is obtained by extracting fiber molecules from natural lignocellulose with cotton linters and wood as raw materials and modifying them.

Ice silk is the trade name of a chemical fiber. Ice silk is also called rayon, viscose fiber and viscose filament. This kind of fiber has better hygroscopicity and breathability than ordinary viscose fiber, and also has better shape retention and drape.

Ice silk mostly appears in the form of filament textiles, so it feels droopy and easy to slip when held in your hand. Due to the physical and chemical characteristics of ice silk, it is suitable for making summer clothes, so the ice silk T-shirt came into being.
