Study of the Operation of a Movable Navel of a Rotor Spinning Machinev

Аннотация

An intensive increase in demand for OE based yarns of a wide assortment requires the improvement of spinning machines on which the processes of its formation is carried out. Recently, as a result of a sharp increase in the speed of OE spinning, the productivity of the machine has increased, and the quality indicators of the yarn produced have deteriorated, i.e. unevenness in its structure and properties increased. A number of works are devoted to studies on the assessment of the structure and properties of OE yarns. The features of the forming structure are described, for the study of which microscopy, a method of transverse sections has been used, and the migration of fibers in the yarn was evaluated . The structure of the yarn is also evaluated by the results of the processes of its formation and determination of its properties . Studies have also been carried out to determine the influence of the parameters of the spinning chamber on the structure and properties of yarn. The structural engineering features of combined OE yarn were also studied. However, in the above-mentioned studies, there are no recommendations for improving the structure and properties of OE yarn, and reducing unevenness produced at high yarn speeds. In order to improve the structure and properties of OE yarns and increase the competitiveness of manufactured textile products from it, there is a need to improve the design of the working bodies, which directly affect the structural changes and the yarn tension. To achieve this goal, a device of a thread-returning mobile navel has been developed, and as a result of the study, the advantage of its use has been proved.
