研究了同一喷丝板上不同喷丝孔直径对涤纶POY单丝直径与双折射率的影响。
The effect of spinneret hole diameter on the filament diameter and birefringence of PET POY was studied by using the same spinneret.
随着喷丝孔孔径的增大，涤纶poy单丝直径增大，单丝的取向度降低，双折射率减小。
While increasing the diameter of spinneret hole, the filament diameter of PET POY was increased, both the orientation and the birefringence of PET filament were decreased.
