Study of the influence of the output surface of the confusor inside the adapter on the location of fibers in the yarn in a rotor-spinning machine

Abstract

In the article, the influence of the confusor inside the adapter on the output surface of the rotor-spinning machine on the location of the fibers in the yarn was studied. The properties of carding sliver for yarn production were investigated. In the experimental work, the uniformity and stability of the velocity field of each channel for moving fibers in an aerodynamic device were checked. Airflow was carried out at a speed of 20 m/s. During the research, 20-tex yarns were produced in 3 different samples by changing the output surfaces of the confusor inside the adapter S1=19.6 mm2, S2=12.6 mm2, S3=7.1 mm2 in the rotor-spinning machine. The cross-section and length of the produced yarns were examined under a microscope. The location of the fibers in the conical channel in the yarn was studied.
