The spinneret material used in melt spinning , the spinneret shape , the rheological behaviour of the melt in orifice , the spinneret microhole geometric important indexes , the orifice arrange mode , the orifice opened scope and distance , the spinneret thickness were introduced in detail 摘要介绍了熔融纺丝所用喷丝板的材质、喷丝板形状、熔体在喷丝孔中的流变特征，喷丝板微孔几何形状重要参数，喷丝孔排列方式，开孔范围及孔间距，喷丝板的厚度。
Through threshold transforming , dilation and area labeling of the source image which , input into computer by scanner , contains the information of the whole spinneret , the system can compute locations of every micro - hole . then the pickup camera equipped with microscope is moved on every micro - hole driven by step - by - step motors . the image of the micro - hole is captured to the computer after auto - focusing 该系统经过对扫描仪扫入的整块的喷丝板图像进行阈值处理、图像膨胀、区域标记等图像处理的手段分析出各个微孔的分布情况，然后用步进电机驱动加有高倍显微镜的摄像头自动搜寻到每个微孔，对微孔自动的聚好焦后，采集微孔图像。
Abstract : the formation technologies , the structure and properties of tcs microporous man - made yarn - kind new polyester fibre which was spinned in tcs with some micrometallic - oxide have been studied . the results indicate that the rheological behaviour and spinnability of commixed polyester melt , and the structure and properties of the fibre , are relative to the spinning temperature , melt pressure , microporpus size for spinning , formation conditions , thermo - vascellum temperature , thermo - vascellum position and rolling speed , besides the viscosity of polyester cuts , coacervation particles , adding amount and size of micrometallic - oxide 研究表明， tcs微孔化共混聚酯熔体在成型加工中的流变行为和可纺性，及其纤维的结构性能除了与原料切片的特性粘度、凝聚粒子和共混聚酯中超细金属氧化物微粒的添加量、粒径等因素的影响有关外，还与纺丝温度、纺丝熔体压力、喷丝板微孔尺寸、冷却成形条件、热管温度、热管安装位置以及卷绕速度等因素的影响密切有关。
