  • Method for preparing cellulose acetate fibers
    Patent number: 6184373
    Abstract: A method for producing an organic cellulose derivative fibrillated fiber includes the steps of mixing a cellulose ester containing stream and a coagulant stream in a first zone of relatively moderate turbulence to produce a slurry containing cellulose ester fibers, passing the slurry containing cellulose ester fibers to a second zone having relatively low turbulence for a sufficient time to increase the hardness of the cellulose ester fiber; and passing the cellulose derivative fibers through a third zone having relatively high shear to produce a fibrillated fiber having a diameter of about 0.5 to about 50 microns and a degree of fibrillation greater than about 6.
