利用普通涤纶高速纺及配套设备纺制细旦丝的工艺探讨

PRODUCTION OF MICROFILAMENTS ON CONVENTIONAL PET HIGH SPEED SPINNING EQUIPMENTS

探讨了利用普通涤纶高速纺及配套设备纺制细旦丝的工艺条件,指出须慎重选择适宜的喷丝板和保证组件质量,采用较高的纺丝速度和较低的拉伸比是解决细旦丝具有良好染色性与减少损伤的有效方法,另外,工艺参数的控制精度和稳定性也是保证细旦丝质量的重要环节。

The technology of producing microfilaments on conventional PET high speed spinning machine and its accessary equipments is explored.it is indicated that the effective ways to solve the problems of bad dyeability and damage of microfilaments are the careful selection of suitable spinneret and guarantee of the assembly's quality in addition to the higher spinning speed and lower drawing ratio. Besides ,precision control and stability of technological parameter are also the key points to the quality of microfilaments.
