Acetate fibers are molded from solutions of cellulose acetate in organic solvents (triacetate cellulose in a mixture of methylene chloride and alcohol, secondary cellulose acetate in acetone), usually by the so-called dry method.By this method filaments, the so-called acetate silk, are obtained.ater acetate fiber production decreased after the appearance of new types of valuable synthetic fibers. In 1967 the world output of acetate fibers was 397,000 tons, 6.4 percent of the total production of chemical fibers. Rogovin, Z. A.
