【Abstract】 The technical combination of secondary mixing with antistatic agent,profile spinning and fine denier spinning was used to produce fine profiled antistatic polypropylene fiber. The weight ratio of built antistatic system about 0.7% offtered good antistatic effect. The main spinning technolgy was drawn up by rheological investigation.The effects of the spinning parameters, such as spinning temperature, spinning speed, dpf, etc., on the structure and properties of the resulted fiber were also analyzed.更多还原
