Rotor Spinning

One of the open-end spinning methods is called rotor spinning because the rotor is used to condense single fibers. At the beginning, airflow was mainly used, which is also called airflow spinning in China. The spinning speed of the rotor spinning is high, the winding capacity is large, the spinning of low-grade cotton and waste noil has good spinnability, and the working environment is also greatly improved.

Classification

The main components used in air spinning are rotor cup, cotton feeding mechanism, carding roller, yarn guide tube and twist resistance device, etc. The whole set of devices is called spinning device. According to the method of generating negative pressure in the rotor, it can be divided into two categories: self-exhausting type and suction type. The self-exhausting spinning machine has a number of exhaust holes on the bottom side of the rotor. When the rotor rotates at a high speed, it will produce a centrifugal pump effect and make the rotor have a negative pressure. The airflow in the self-exhausting rotor cup is mainly replenished from the fiber delivery pipe, and then discharged to the small hole on the bottom side after passing through the condensate tank, so the fiber delivery pipe can be appropriately short. After the fiber comes out of the conveying pipe and before it reaches the condensation groove of the rotor, it may rush directly to the sliver that has been twisted and drawn out, forming loose outer fibers, which will affect the strength and appearance of the yarn. To prevent this, isolation discs must be employed. The airflow in the rotor cup of the air-suction spinning machine is supplemented by the fiber delivery tube and then sucked out from the cup mouth, so the fiber delivery tube must extend into the cup and be closer to the wall, so the delivery tube is relatively long. Due to the different airflow directions in the rotors of the two spinning machines, the spinning conditions are also different. Dust is easy to accumulate in the condensation groove of the self-exhausting rotor cup, and the dust in the suction rotor cup is easily sucked away by the airflow, so the condensation groove is relatively clean. After the spinning end is broken, there are remaining fibers in the self-exhausting rotor, which need to be removed before splicing. The remaining fibers after broken ends in the air-suction rotor can be sucked away from the mouth of the cup with the airflow, so it can be directly spliced. In order to strengthen the ability of the rotating sliver in the cup to transfer the twist to the condensation groove, to increase the strength of the yarn at the peeling point in the condensation groove, reduce the breakage rate and reduce the yarn twist. Both spinners must use a twist arrester in the rotor
