Abstract

The work aimed at improving the quality indicators reinforced sewing thread LL.

As result of the work done, the force of normal pressure of the braid fibers on the core component of the reinforced yarn is determined. The frictional force between the complex filament and the coating in the structure of the reinforced yarn is calculated. The force of resistance of the coating fibers to the misalignment of the filament is calculated from the thread.

The influence of unevenness on the linear density of the coating on the degree of fastening of the braid on the surface of the complex filament is established. The dependence of the specific frictional force arising between the coating fibers and the complex filament in the braiding layers of the reinforced 16.7 tex fiber of the normalized value of the linear density of the filament is obtained. The nominal linear density of the filament is calculated in the most thinned place, taking into account the deviation of the linear density in the smaller direction.
