A man-made fiber (specifically, a type of rayon) that's derived from wood pulp cellulose.

A manufactured regenerated cellulose fiber produced from naturally occurring polymers. It is neither a truly synthetic fiber nor a natural fiber, it is a semi-synthetic fiber. Rayon usually has a high luster quality giving it a bright shine. SEE RAYON.  NOTE: “Viscose Rayon” is the most volatile construction because it becomes weak when wet and is [..]

A viscous orange-brown liquid obtained by chemical treatment of cellulose and used as the basis of manufacturng rayon and cellulose film. A fabric made from this material.

(n) a cellulose ester obtained by treating cellulose with caustic soda(n) a rayon fabric made from viscose (cellulose xanthate) fibers

Rayon, or “artificial silk,” created using the viscose process in which a solution of cellulose (wood pulp or cotton) is treated with chemicals and passed through nozzles or spinnerets to form filaments. Viscose is known for its softness to the hand and durability of the cloth.

A synthetic fiber used to make rayon.  Viscose was invented in 1891 and was one of the first synthetic fibers. Because of environmental concerns it is less used than it once was.

A viscous orange-colored liquid obtained by treating cellulose with caustic alkali solution, then with carbon disulfide.
