摘要
采用当量直径法对异形喷丝板的尺寸进行设计、计算。讨论了喷丝孔孔型、喷丝板特征尺寸、异形孔的排列方式、冷却条件对纤维异形度的影响。选择三叶异形喷丝孔叶片 ,长宽比为 4 1,当量直径在0 .15～ 0 .45mm ,环吹风速度 1.1m /s ,可制得异形度高达 61.5
The dimension of shaped spinneret was designed and calculated by equivalent diameter analysis. The effects of spinneret hole shape, characteristic dimension of spinneret ,hole arrangement and cool conditions on degree of profile were discussed. The degree of profile could be up to 61.5% by using spinneret with L/D ratio of 41 and equivalent diameter of 0.15～0.45 mm and keeping circular blow velocity at 1.1 m/s.
