Because of this expense, production ceased early in the 1900s.Nitrocellulose was briefly known as "mother-in-law silk".

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

The triacetate is soluble only in chloroform making the method expensive.

The discovery that hydrolyzed cellulose acetate is soluble in more polar solvents, like acetone, made production of cellulose acetate fibers cheap and efficient.

The physical properties of rayon remain unchanged until the development of high-tenacity rayon in the 1940s.

Further research and development led to high-wet-modulus rayon (HWM rayon) in the 1950s.This allowed rayon to become a popular raw material in textiles.
