Combing, drawing, roving process 1.Combing process The combing process channel and the top combing brushes of the cylinder are not smooth and clean. There are burrs and hanging flowers in the channel of the coiling plate, resulting in the production of silk. When the cloth surface is disassembled an...

Small slub defects are common in the production process. To eliminate small slub defects, supervision must be started from the previous process of the fabric. Such defects are all small slubs when viewed from the cloth surface. According to the test data analysis of the evenness tester and the cloth...

Quality control is an important aspect of improving product quality, and the idea of ​​"quality " 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, and do...

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...
