摘要
讨论了"┃·"异形喷丝板的设计、纺丝工艺及后加工工艺,计算出喷丝板毛细孔的当量直径、单孔流量、剪切速率、喷丝头拉伸比,验证了喷丝孔的结构参数是影响可纺性的关键因素。
Design of'┃~·'Profiled spinneret pack?fiber-spinning process and afterprocessing was studied in this paper. The diameter, flow, shearing rate ,draw ratio and pressure difference were calculated. It is verified that the key influence factor of spinnability is configuration of capillary hole.
