摘要
介绍了5000 t/a聚酯纺粘针刺土工布的生产工艺及设备。纺粘针刺非织造土工布纺丝与全拉伸长丝纺丝工艺基本相同,应严格控制侧吹风条件,包括风温、风湿度,保证出风均匀。为达到强度要求,丝束速度应超过4500 m/m in,将摆丝频率与摆丝角度调整到最佳数值。网下吸风风量应大于拉伸管出来的风量。应根据产品品种、规格选择适用的预、主针刺机型号进行合理化搭配。
The production technology and equipments of 5 000 t/a PET spunbonded needle-punched geotextile are introduced. The spinning technology of the spunbonded needle-punched geotextile is nearly same to the fully drawn filament. The quench air conditions should be controlled strictly,including the air temperature, air humidity and air evenness. In order to meet the strength demand, the tow speed should exceed 4 500 m/min. The sway frequency and sway angle should be adjusted to the optimum value. The air volume coming from the suction system should be large than the air volume coming from the drawing pipe. The preneedle and main needle machine type should be reasonable matched according to the product variety and specification.
