what kind of material is viscose
In Europe, though, the fabric itself became known as viscose, which has been ruled an acceptable alternative term for rayon by the U.S. Federal Trade Commission (FTC). The viscose method can use wood as a source of cellulose, whereas other routes to rayon require lignin-free cellulose as starting material. The use of woody sources of cellulose makes viscose cheaper, so it was used on a larger scale than the other methods.
