Winding process Low speed and low tension are the key. The automatic winding process is the process with the largest increase in hairiness. Generally, it should be increased by about 3 times, especially for hairiness of 3 mm and above, which increases geometrically. This is mainly caused by the fric...

Spinning process The spinning process is not only the point of twisting hairiness, but also the point of serious increase in process hairiness. Therefore, the various conditions of the spinning process have a great influence on hairiness, and it is a key process for controlling hairiness. 1) Optimiz...

Cleaning process The focus is to reduce fiber damage. The chemical fiber is al free of impurities, reducing the speed of the beaters and enlarging the distance between the gripping points, which can improve both hairiness and neps. The air flow is smooth, no choking, no traffic jams. The airflow is...

The hairiness parameter is generally expressed by the hairiness index. The more intuitive is the number of hairiness roots, and the control of hairiness is mainly to control the harmful hairiness, that is, the hairiness of 3 mm and above. Use of raw materials (1) The greater the torsion and bending ...

With the continuous improvement of customer requirements, the requirements for yarn hairiness have become more and more obvious. Whether it is knitting or weaving, the requirements of customers for hairiness continue to increase. Zhou Wengang worked hard to systematically and comprehensively explain...

Roving quality has a direct effect on spinning quality. The roving drafting process should be reasonably configured through process selection to reduce the roving evenness CV and quality unevenness as much as possible, and create good conditions for the spun yarn to improve the evenness and increase...
