METHOD FOR PREPARING NATURAL FIBER COMPOSITE MATERIAL FOR INJECTION MOLDING BY USING CONVERGENT NOZZLE HEATING JIG
Document Type and Number:
WIPO Patent Application WO/2020/105996
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a natural fiber composite material for injection molding by using a convergent nozzle heating jig, the method comprising the steps of: (S1) twisting natural fiber and synthetic fiber; (S2) heating and compressing the twisted yarn while allowing same to pass through a convergent nozzle heating jig (100), so that the synthetic fiber is compressed while being melted, and thus is fused into the natural fiber; and (S3) pelletizing the mixed twisted yarn.
