1. Reasonable configuration of opening and cleaning, carding and combing processes

The effect of reducing the content of short linters on the quality of spinning products. Because in the drafting and floating zone, those shorter fibers cannot be effectively controlled, and large shift deviations are prone to occur, so this will affect the spinning quality, especially The deterioration of the yarn sliver is more serious. Therefore, spinning enterprises must reasonably configure the open-cleaning, carding, and combing processes, and moderate blows to the open-cleaning cotton, so that fiber damage can be reduced; at the same time, it must insist on "appropriate carding transfer and mixing For carding, the process route of taking into account both short-staples requires a reasonable selection of card clothing and technology, strict control of the combing sliver lint rate, and optimization of the spinning drafting technology in the production process to improve the quality of cotton yarn.

2. Optimum rubber roller and apron

If spinning enterprises want to improve the quality of spinning, they can also strengthen the optimized selection of rubber rollers and aprons. In the spinning production process, the rubber roller with high elasticity and low hardness is very suitable for heavy pressure, which can effectively improve the production effect of spinning. Moreover, it is necessary to strengthen the overall consideration of gripping force, drafting force, and control force, to adjust the relationship between the various forces simultaneously, and to effectively distribute and coordinate. At the same time, it is necessary to ensure that the rubber roller and the rubber ring can run at a uniform speed, try to avoid cracks, and strengthen the utilization of the high yield resistance of the rubber ring.

3. Improve evenness and reduce yarn defects

Cotton yarn evenness generally refers to the degree of unevenness in the weight of cotton yarn that meets the specified linear density requirements. Yarn defects include frequent yarn defects and occasional yarn defects. Among them, the defects of long details and long slub yarns are more harmful to the quality of the cloth surface, and the defects of short details and short slub yarns are more harmful to the quality of knitted jerseys and high-density woven fabrics. General quality improvement measures focus on the improvement of even CV value and frequent yarn defects, and there is no condition to check long details and long thick yarn defects. In the production process, we should pay close attention to such yarn defects and strictly prohibit their occurrence.
