| Abstract: | It was proved by the calculation of hydromechanics and reaction kinetics that the ultra-long time stagnant degradation of the melt near the pipe wall was the key factor that has effect on the spinnability of the melt direct spinning.By using the new static mixer with high decorticating efficency and low pressure drop,the ultra-long time stagnant melt quantity was sharply reduced,the spinnability of the melt direct-spinning was obviously improved. |
