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.

In this article, the movement of fibers in the air channel and the rotor in the rotor spinning machine was studied. In the experimental work, the uniformity and stability of the velocity field of each channel for moving fibers in an aerodynamic device were checked. In this case, the airflow speed was changed from 5 m/s to 30 m/s. Also, differential equations of motion along the OX and OY axes were created taking into account the air resistance. When determining the movement of fibers in a conical channel, the total speed was divided into components, constant values were found, and general equations of motion were derived.

In this article, the possibility of controlling the movement of fibers inside the tube in a certain process by changing the dimensions of the tube of the pneumomechanical spinning machine confusor was determined. As a result of processing the experimental data, taking into account the deformation of the belt element, a formula was obtained that clearly expresses the increase in the drag force with the increase in the values of the airflow speed. Also, to improve the level of straightening of the fibers during the flow in the tube, the optimal values of the air speed along the OX axis of the fibers in the conical tube, the surface value of the outlet part of the tube, the slope angle, and the air resistance coefficient were determined.
