What fiber is Tencel?

Tencel is just a trade name, and its essence is regenerated fiber, which is viscose fiber. It takes trees as raw materials, and its production process is similar to viscose fiber. Tencel is a patented product of Austrian Blue Crystal Company, with high fiber strength and good hygroscopicity, claiming that its performance is better than natural fiber. Because it is a patented product and a monopoly, the price is also very high.
