Acetate Fibers

Acetate fiber was first produced by Camille and Henri Dreyfus, two Swiss brothers whose research efforts began in 1904 in a shack behind the house of their father. Within a year, the innovative pair had developed the first commercial cellulose acetate manufacturing process. The material was soon utilized in such products as films and toiletries, and during World War I, the brothers created acetate dope, which was used as a protective coating for airplane wings. By 1913, the pair had successfully created acetate fibers in the laboratory, but due to other concerns, the mass manufacture of the filaments did not immediately occur. It was not until 1924 that the first acetate fiber was commercially produced in the United States, where it was introduced under the trade name Celanese.
