Abstract: PROBLEM TO BE SOLVED: To manufacture cellulose acetate having high quality in a high yield by setting the mean value of the maximum inclined angle to a specified value or above when a pulp chip having a specified range of weight and a specified size is placed on the surface of a splitter functional part and inclined in the direction where splitting shearing force is generated. SOLUTION: In a splitter 10, two sheets of splitting means 5 and 6 consisting of splitting means bodies 11 and 12 and splitter functional parts 21 and 22 formed on the surface except their central part are arranged by facing each other. When a pulp chip having 1.7-2.0 g weight, 50 mm long and 50 mm wide is placed on the surfaces of the splitter functional parts 21 and 22 incorporated in the splitting means bodies 11 and 12 based upon a prescribed measuring method, and the surfaces are inclined in a direction where shearing force is generated, the mean value of the maximum inclined angle capable of holding the pulp chip is set to be 25 degrees or above. Thus, secondary cellulose acetate excellent in transparency, filtering performance and spinnability can easily be manufactured industrially.
