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。
The paper compares the laser light strip geometric center extraction process method and the skeleton method, and adopts the skeleton method whose thinning precision is much higher.
本文通过对比激光几何中心提取法及骨架法，使用了细化精度更好的骨架法。
