How to actively preventing man-made yarn defects in the spinning process

Quality control is an important aspect of improving product quality, and the idea of ​​"quality first" must be implemented in all production operations. Actively preventing man-made yarn defects in the spinning process is one of the effective ways to ensure yarn quality. Prevent man-made defects, an... read more

The winding process is a serious cause of hairiness in the yarn process

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... read more

What are the important steps in the spinning process

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... read more

The geometry of the openings have a great influence on the hairiness of the yarn

Cleaning process The focus is to reduce fiber damage. The chemical fiber is almost 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... read more

Main methods and measures to control hairiness

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 ... read more
