聚酯(PET)纺粘法非织造布纺丝工艺探讨

Discussion on Spinning Technology of PET Spunbond

聚酯 (PET)纺粘法非织造布的纺丝工艺与传统的PET高速纺工艺有许多相似之处 ,但两者牵伸方法不同 ,牵伸速度不同 ,所制成的产品不同 ,所以纺丝工艺的要求也就不同。对影响聚酯 (PET)纺粘法非织造布纺丝工艺的重要环节 :切片质量、纺丝温度、纺丝压力和纺丝速度、泵供量、喷丝板、冷却成形等进行了探讨。

There are many similarities in the spinning technology between the PET spunbond and the PET high speed spinning, but the requirements of the two spinning technology aren′t the same because of the differences on the way of draw off, the speed of the draw off and the requirements of the two products. This essay discusses spinning technology of PET spunbond, it focuses on the important factors, which affect the spinning: the quality of PET chip,the temperature, pressure and speed of spinning, the output of spinning pump, the structure of spinneret, cooling process of filament, etc.
