Embodiment 1
[0044] A method for preparing multi-colored cellulose plates using scented cellulose, comprising the steps of:
[0045] a. Put 60 parts of cellulose acetate and 20 parts of diethyl phthalate into a high-speed mixer and mix for 20 hours to prepare mixture I;
[0046] b. Add 0.01 part of lily flavoring agent to mixture I, mix and stir evenly, and let it stand for 20 hours to prepare mixture II;
[0047] c. Put part of the mixture II into a twin-screw extruder for melt extrusion, the extrusion temperature is 165°C, the extrusion speed is 20r / min, cool to 30°C and then pelletize to obtain colorless flavor cellulose;
[0048] d. Put part of the mixture II into a twin-screw extruder for melt extrusion, and add 1 part of Lithor red pigment powder during the melt extrusion process, cool to 30~40°C and cut into pellets to obtain colored and fragrant fibers white;
[0049] e. Mix the obtained colorless and flavored cellulose with colored and flavored cellulose and put them into a hot ...
