Cellulose fiber - Wikipedia

Cellulose fibers are manufactured from dissolving pulp. Cellulose-based fibers are of two types, regenerated or pure cellulose such as from the cupro-ammonium process and modified cellulose such as the cellulose acetates. The first artificial fiber, known as artificial silk, became known as viscose around 1894, and finally rayon in 1924.
