摘要
介绍了在其他纺丝工艺参数不变的条件下，把挤压机加热温度先低后高的加热模式，改为先高后低，不但生产更趋于正常，断头率减少，成品率提高到９８％，不匀率降低。
The conventional heating method of extruder was to raise the heating temperature from the lower level upward. When the conventional method was changed into from the higher level downward, the production became more stable under other normal process conditions. The yield was increased and the product quality was improved.
