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

The shape and related characteristics of ring spinning hairiness

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... read more

Roving quality has a direct impact on spinning quality

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... read more

The drawing process has a greater impact on the quality of the spun yarn

In the spinning process, when the spinning tension is greater than the strength of the cotton yarn, it will break, which is the essence of spun yarn breakage. Therefore, increasing the minimum value of cotton yarn strength and reducing the single-strength CV value is a systematic project. Drawing pr... read more
