对毛毛虫形粗旦仿毛锦纶6的生产工艺进行了研究分析,发现合理控制纺丝速度、纺丝温度、侧吹风、热辊温度和拉伸比等工艺参数,改进上油方式,可以生产出物性指标良好,并具有较好仿毛手感的粗旦仿毛锦纶6FDY。试验表明:纺速在4000~4300m/min,拉伸比1.1~1.3,热拉伸温度150~170℃,侧吹风速0.10~0.18m/s,下调上油位置,延缓上油时间,可以生产出外观好、染色均匀、性能指标好、仿毛手感好的粗旦仿毛锦纶6全拉伸丝。
The production process of caterpillar-like rough wool imitation wool nylon 6 was studied and analyzed. It was found that by controlling process parameters such as spinning speed, spinning temperature, side blowing air temperature, hot roll temperature and draw ratio, etc., oil refining method can be improved Outstanding physical indicators, and has a good hand-like coarse wool imitation wool nylon 6FDY. The test shows that the spinning speed is in the range of 4000-4,300 m / min, the draw ratio is 1.1-1.3, the hot stretching temperature is 150-170 ℃ and the side blowing speed is 0.10-0.18 m / s. The oiling position can be lowered and the oiling time can be delayed to produce The appearance of good, uniform dyeing, good performance indicators, good wool-like hand-rough wool imitation wool 6 fully drawn wire.
