THE INFLUENCE OF MODERN FINISHING ON THE TECHNOLOGICAL CHARACTERISTICS OF KNITTED FABRICS

Abstract

The problem of competitiveness of knitted garments produced by domestic enterprises is a complex set of interrelated organizational, information and technological, technical and economic tasks. Solving these tasks is a fundamental prerequisite for reducing the cost of production, improving its quality and increasing the competitive presence of production in the consumer goods market. Taking into account the further growth of requirements for the quality of ready-made garments, the issues of improving a number of operations and processes, introducing new technologies and providing them with technical means are gaining particular importance. Efficient solution ofthese tasks should be accompanied by a determined choice and forecasting of the assortment, technological modes and parameters, the basics of design and calculation of processes. This work considers to determine the impact of modem finishing on the technological characteristics of knitted fabrics in the process of sewing production by using nano-sized organosilicon softeners and to assess the possibility of their improvement. Theoretical and experimental studies of the work are based on the basic principles of textile materials science. During the experimental studies, standard laboratory methods were used that reproduce the process of softening treatment of knitted fabrics. The technology of finishing of textile materials was taken as the object of the study. As the subject of the study, samples of knitted fabrics made by interlock weaving were chosen. The technological process ofprocessing was performed on industrial sewing equipment Bruce B500 4+hread overlock. During the study, it was determined that the use of innovative finishing, in particular nano-sized organosilicon softeners, improves the technological characteristics of knitted fabrics and positively affects the stability of the linear dimensions of the knitted fabric. This indicates that the final treatment of knitted fabrics with nano-sized organosilicon softeners can be considered as a way to reduce the technological complexity of the sewing process. The scientific novelty of the work lies in increasing the efficiency of technological processing of knitted fabrics on sewing equipment by using the final treatment of fabric samples with nano-sized organosilicon softeners. The results of the study can be used at sewing enterprises in the design of parts and the manufacture of knitted clothing, as well as in the development of new materials with improved properties.
