Frank Hastings Griffin invented the double-godet, a special stretch-spinning process that changed artificial silk to rayon, rendering it usable in many industrial products such as tire cords and clothing.

Nathan Rosenstein invented the "spunize process" by which he turned rayon from a hard fiber to a fabric.

Because of this expense, production ceased early in the 1900s.

Nitrocellulose was briefly known as "mother-in-law silk".

When a solution of cellulose in cuprammonium hydroxide comes into contact with sulfuric acid, the cellulose begins to precipitate from the solution.

The sulfuric acid reacts with a complex compound of copper and dissolves it. After some time, sulfuric acid reacts with the complex compound and washes out the copper salts from the fibers. Rayon or artificial silk is a manufactured regenerated cellulose fiber.

This allowed rayon to become a popular raw material in textiles.

Paul Schützenberger discovered that cellulose reacts with acetic anhydride to form cellulose acetate.

They named their material "viscose", because its production involved the intermediacy of a highly viscous solution.

The process built on the reaction of cellulose with a strong base, followed by treatment of that solution with carbon disulfide to give a xanthate derivative.

The xanthate is then converted back to a cellulose fiber in a subsequent step. Courtaulds formed an American division, American Viscose, (later known as Avtex Fibers) to produce their formulation in the United States in 1910.

The first commercial viscose rayon was produced by the U. The name "rayon" was adopted in 1924, with "viscose" being used for the viscous organic liquid used to make both rayon and cellophane. The viscose method can use wood as a source of cellulose, whereas other routes to rayon require lignin-free cellulose as starting material.

In Europe, though, the fabric itself became known as "viscose", which has been ruled an acceptable alternative term for rayon by the U. The use of woody sources of cellulose makes viscose cheaper, so it was used on a larger scale than the other methods.

It is made from purified cellulose, primarily from wood pulp, which is chemically converted into a soluble compound.
