Products and Applications ➢ 2. Cellulose Acetate And Triacetate Fiber Process Description – All cellulose acetate and triacetate fibers are produced by dry spinning. The typical process for the production of cellulose acetate fibers as follows: ❖(1) Dried cellulose acetate polymer flakes are dissolved in a solvent, acetone and/or a chlorinated hydrocarbon in a closed mixer. ❖(2) The spinning solution (dope) is filtered. ❖(3) The dope is forced through spinnerettes to form cellulose acetate filaments, from which the solvent rapidly evaporates as the filaments pass down a spin cell or column. ❖(4) The filaments then undergo several post-spinning operations for cigarette tow. ❖(5) Or the filaments are wound onto bobbins
