| Abstract: | 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. |
