Purpose. To determine the effect of nanosized organosilicon softeners on the indices of the technological properties of a knitted fabric, to assess the possibility of their improvement through the use of innovative finishing processing. Methodology. Theoretical and experimental studies are based on the basic principles of textile materials science. In experimental studies, standardized methods and techniques were used, which are reflected in the laboratory by providing softening treatment for knitted fabrics. The sewing process was performed on a Juki DLL-8100e industrial sewing machine. The stitch frequency of the stitches was determined by the registration method. Finding. It is determined that the use of nanosized organosilicon softeners significantly affects the performance of the technological properties of a knitted fabric. It was found that the Kolosil nanosized organosilicon softener, which was used by the selection method at a concentration of 4% of the processed material, has a maximum effect on the total deformation and increases the proportion of the slowly inverse deformation component. It is shown that the use of softeners has a positive effect on the stability of the linear dimensions of a knitted fabric. It is proved that the final processing of knitted fabric with innovative nanosized organosilicon softeners can be considered a factor in reducing the technological complexity of garments. Originality. The scientific hypothesis has been experimentally confirmed in the use of nanosized organosilicon softeners to improve the indicators of the technological properties of a knitted fabric. It is shown that treatment with nanoscale softeners causes changes in the structure of fibers at the micro level, which are of paramount importance for the formation of technological properties of a knitted fabric. Practical value. The research results can be used in the development of new materials with improved properties, in the design of clothing parts and in sewing knitted fabrics. [ABSTRACT FROM AUTHOR]
