Fabrics woven or knit from acetate filament yarns have the look and feel of luxury. Consisting of pure cellulose acetate, Estron acetate yarn is available in bright and dull lusters. Eastman has been a producer of high-quality cellulose acetate fibers and yarns since 1931. Unexcelled technology and raw materials are key foundations of these businesses. Chromspun solution-dyed, acetate yarn has the same generic composition as Estron acetate yarn except for coloring agents added at the dope stage before the yarn is spun.
