Background

Open-end spinning is a novel spinning technology which utilizes air flow to condense, twist and output fibers into yarn in a spinning cup which rotates at a high speed. Mainly by a plurality of components such as carding rollers, spinning cups, false twisting devices and the like. The carding roller is used for grabbing and carding the fed cotton sliver fibers, and the grabbed fibers can be thrown out through centrifugal force generated by high-speed rotation of the carding roller. The spinning cup is a small metal cup, the rotating speed of the spinning cup is more than 10 times higher than that of the carding roller, and the air in the cup is discharged outwards due to the centrifugal effect; according to the principle of fluid pressure, cotton fibers enter the airflow cup and form a fiber flow which continuously moves along the inner wall of the cup.
