Chemistry - Polymer Question with Solution | TestHub

Viscose rayon is a regenerated cellulose fiber. It is obtained by the chemical treatment of natural cellulose, such as wood pulp. Since it is derived from a naturally occurring polymer but modified chemically, it is classified as a semisynthetic fiber, not a purely synthetic fiber.

In the viscose process, cellulose is often represented as $\text{Cell-OH}$ to indicate the reaction of its hydroxyl groups with sodium hydroxide and carbon disulfide to form cellulose xanthate.

Therefore, the statement that it is a synthetic fiber is incorrect.

Answer: It is synthetic fiber.
