feed 24 to achieve a 34 diluted dope 34 feed 25 the low vapor pressure solvent should have a boiling point above 75 u00b0 c more preferably above 95 u00b0 c and most preferably above 115 u00b0 c acetic acid may be used as the low vapor pressure solvent the acetic acid supplied to mixer 22 may be a 75 wt percent acetic acid solution in water the diluted dope 25 is fed from first mixer 22 to a second mixer 26 fluffed pulp 28 is also fed to the second mixer 26 the fluffed pulp may come from a pulp sheet roll 30 which is fed through a hammer mill 32 the pulp sheet roll 30 is a conventional roll such as that produced in paper making although chemical grade pulp sheets are to produce cellulose acetate this more expensive cellulose should not be necessary the hammer mill 32 chops up the sheet to make individual fibers other similar equipment beside the hammer mill may also be used in the second mixer 26 cellulose acetate is coated on the cellulose of the fluffed pulp the temperature in the second mixer 26 is not critical and may be between about 100 u00b0 f.
