IMPROVING THE EQUIPMENT FOR WASHING LOCAL COARSE WOOL

Abstract

This thesis examines the existing problems in the process of washing local coarse wool and proposes an improvement to the comb-like mechanism that ensures uniform movement of wool in the washing bath. The proposed solution aims to reduce the entanglement of wool fibers and facilitate subsequent technological stages. Wool is an important raw material for the textile industry among natural fibers. Its quality directly affects the properties and competitiveness of the finished product. Therefore, improving the initial processing of wool, increasing the efficiency of existing equipment, and rational use of resources are among the urgent tasks. Raw wool may contain grease-sweat residues, plant particles, mineral impurities, and other contaminants. The main purpose of washing wool is to separate these impurities and prepare the raw material for subsequent processing stages. In the traditional washing process, wool is fed into special baths, treated with a washing solution, and excess liquid is removed using squeezing rollers. In existing devices, wool may not mix evenly enough with the washing liquid from the moment it enters the bath until it exits, which can lead to entanglement of fibers. Therefore, a mechanism is needed to ensure uniform movement of wool in the bath and effective contact with the washing solution. The proposed mechanism aims to approximate the movement direction of the comb to a nearly straight line in a certain section. Such movement is expected to facilitate the gradual displacement of the wool mass in the bath, stabilize its interaction with the washing solution, and prevent excessive entanglement of fibers. Optimizing the trajectory of the working comb is one of the important directions in improving the process of washing local coarse wool. The smooth and uniform movement of the comb can help effectively mix the wool with the washing solution and reduce fiber entanglement. It is advisable to determine the technological effectiveness of the proposed constructive solution through practical tests and to substantiate the main parameters of the device.
