所制成长丝的直径取决于粘胶的喷丝头孔中的流速，而不取决于孔径的大小。
尼龙是采用熔纺工艺制成的，即将由熔化的尼龙切片构成的尼龙熔融体，强制通过喷头的纺丝孔。
利用具有不同孔径的同一喷丝板生产不同线密度和取向度的涤纶POY。
工业化试验表明：当喷丝头负拉伸率为-73%时，纤维可纺性达到最佳状态。
纺丝原液过滤、脱泡，从由两个同心管组成的喷丝头挤出；
1·And also effect of spinneret draw-ratio on fibre aggregated structure and the properties was discussed.
分析喷丝头拉伸比对纤维的聚集态结构及性能的影响。
2·Polyoxymethylene fibers were obtained by high-speed melt spinning with laser irradiation heating near the spinneret, meanwhile the thinning behavior was examined by on-line measurement.
聚甲醛纤维是由高速附近的喷丝头的激光照射加热熔融纺丝获得的，同时变薄的行为进行了检查，在线测量。
1·“But if you look at a silkworm, it only has one kind of spinneret,” she added.
“但桑蚕只有一种吐丝器，”她补充说。
