Abstract

This article examines the influence of the parameters of the coating teeth of the discrete drum on the quality of the OE yarn. Based on the analysis of the conditions for retention of fibers by the covering teeth of the discrete drum, equations were obtained to determine the angle of inclination of the teeth. To determine the effect of the coating parameters of the discrete drum teeth on yarn quality, experiments were performed using the Full Factor Experiments mathematical planning method, and a regression equation was obtained for each variable. As a result, the optimal values of the discretization drum coating teeth of the OE spinning machine were determined.

Highlights

It is known that in order to increase the efficiency of separation of complex fibers into separate fibers and to straighten and parallel the ends of the fibers in the supplied sliver, it is recommended to increase the working speed of the discreting drum
To increase the intensity of the discreting drum (Fig. 1), it has been proved that increasing the number of teeth per 1 cm2 surface of the discretization drum can be done by applying the multi-input wrapping method of teeth and reducing the tooth pitch (Fig. 2) [4,5,6]
From the compatibility of Equations 8-10, it can be concluded that: - the tensile strength of the yarn increases with increasing rotational frequency of the discreting drum and decreasing the pitch of the tooth

Summary

Introduction

It is known that in order to increase the efficiency of separation of complex fibers into separate fibers and to straighten and parallel the ends of the fibers in the supplied sliver, it is recommended to increase the working speed of the discreting drum. It is advisable to use special tooth types so that there is a correlation between the parameters of the discrete drum teeth and the fiber properties. It has been found that the distance between the discrete drum teeth and the angle of inclination of the tooth have a large effect on the processing of the fiber bundle. Taking into account the above, in order to improve the yarn quality performance, theoretical and experimental studies have been conducted to produce a competitive product by changing the geometric shape of the discrete drum teeth and determining the optimal value of the angle of inclination of the tooth [3]
