Cellulose acylate film and method for producing the same |
| abstract |
A cellulose acylate film capable of producing a film with little discoloration and a decrease in mechanical strength and a method for producing the same are provided. A cellulose acylate resin supplied from a hopper 23a is melted by an extruder 22, discharged from the extruder 22, supplied to a die 24, and the molten resin is extruded from the die 24 to be cooled and solidified. And a film manufacturing method using a powdery cellulose acylate resin as a resin that is melted by the extruder 22, and a screw 38 is used as the extruder 22 to form a L / L D is set in the range of 20 to 55, the temperature of the molten resin is set in the range of melting point Tm + 10 ° C. to Tm + 70 ° C. of the cellulose acylate resin, and the degree of vacuum in the extruder 22 after the cellulose acylate resin is melted The average residence time from when the cellulose acylate resin is supplied to the extruder 22 to when it is discharged is maintained within 5 minutes while maintaining the pressure below 100 Torr. To be. [Selection] Figure 1 |
