“…The studies also explored ways to ensure that the working processes of the saw cylinder were uniform [10,11]. Theoretical studies have taken into account the resistance forces generated during the separation of fiber from seed cotton in the form of resistance moments to the performance of the saw cylinder.…”

In the article, the task of reducing the mass of the main working body of the gin, i.e. the cylinder shaft by means of the opening of the groove and the design features of the shaft is determined. Its essence is that the inner groove part of the gin saw cylinder shaft performs the circular side with symmetrical gears and the entry of external slits into the grooves in the corresponding inner slits of the shaft leads to a specific equilibrium of the mass relative to the axis of rotation and increases its strength and reliability in operation. This will increase resource efficiency and reliability by significantly reducing the mass of the shaft and saw cylinders without significantly reducing the bending stiffness, as well as obtaining cotton fiber with the required quality characteristics. The issues of creating and defining methods for calculating high-efficiency machine drives and shafts are especially important in the creation of machines for the ginning industry.

“…The amount of bending of the yarns depends on many factors: the thickness of the weft and warp yarns; to yarn stiffness; type of weaving; density on the weft and warp; to the tension of the yarns during weaving. [8][9][10][11]]…”

It is theoretically and experimentally established that the shrinkage and processing of threads in a towel sample based on various weaves affects its structure, length and width. The bulk of the sample is looped weave and edge and border pieces -plain weave, which fabric has a different degree of shrinkage of the main and the weft yarn, which increases the possibility of using yarns. It is also necessary to take into account the linear density of yarn, the density of fabrics, and their ratio.

“…The amount of sizing can be real and superficial. Usually, in conditions of weaving enterprises, the amount of dressing is set at the level of 0.5-12%, which is determined by the type of fiber, the degree of twisting of a single yarn, linear density, density of the fabric on the weft and the warp yarn, and also by the type of weaving [15][16][17][18][19].…”
