Rotor Spinning Machine, Open End Spinning Machine

Rotor Spinning Machine is a new type of spinning technology that uses air flow to condense, twist and output fibers in a high-speed spinning rotor. He does not use spindles, but mainly relies on opening rollers, spinning rotors, false twisting devices and other components. The opening roller is used to grab and card the fed sliver fibers, and the centrifugal force generated by its high-speed rotation can throw the grabbed fibers out. The spinning rotor is a small metal cup, and its rotation speed is more than 10 times higher than that of the combing roller. The centrifugal action generated by this causes the air in the cup to be discharged outward; according to the principle of fluid pressure, the cotton fibers enter the airflow cup. , and form a fiber flow that continuously moves along the inner wall of the cup. At this time, there is a yarn end outside the cup, which draws out the fibers on the inner wall of the cup and connects them. In addition, the drilling effect generated by the high-speed rotation of the cup with the yarn tail is like "feeding" cotton fibers while adding yarn. The thread is kneaded to connect the yarn with the fibers on the inner wall of the cup, and it is drawn under the winding tension of the yarn bobbin, and the yarn is continuously output to complete the process of air spinning.

Application of open-end spun yarn: thick and thick fabrics, weaving corduroy, fleece fabrics, used in knitwear, woven products and furniture decorations, etc
