A classifier of QR-codes, which are used in light industry and are divided into static, dynamic, combined is developed in this work. Static QR codes can be digital, text or symbolic. Digital QR-codes are divided into subspecies: product code, product price, manufacturer code, date and other numerical designations. Text QR-codes are divided into subtypes: product name, product description, manufacturer and other text designations. Symbolic QR-codes are divided into subtypes: special symbols, formatting symbols and other marking symbols. Combined together, several types of QR codes form a combined code. Frequently static and dynamic QR codes are combined. Dynamic QR codes can only be combined. Based on the survey data, we can assume that the most important are the four main ways to use the QR-code are: “Outdoor advertising”, “Code on goods”, “Electronic ticket” and “Discount code”. Other ways to use a QR code, according to experts, have a much lower impact in terms of application. These include: “Invitation to social networks”, “Tourism”, “Banking”, “Company logo”, “Clothing and accessories”, “Tattoos”. This opinion of experts is typical only for Ukraine, because according to foreign studies, tattooing a QR-code on the human body is quite often met. Taking into account the results of the study, a label for products was made using a QR-code, which contains a link to the site TKSHV – Market. On the site it is possible to get acquainted in more detail with the products made at the department, to provide consumers with information about them. From the site it is possible to go to the Telegram-channel, where it is convenient to ask additional questions, see the process of creating a QR-code and more. It is also planned to create other channels on social networks, such as Instagram, Facebook, Viber. This will allow the consumer to use a more convenient social network.

The article considers an improved method of comprehensive assessment of the impact of washing at home on the physical and mechanical properties of textile materials intended for the manufacture of children’s casual wear. In developing the methodological basis for assessing the change in the properties of fabrics from washing, we used the results of our own observations, which allowed us to analyze the operating conditions of preschool children’s clothing, activities and characteristic movements of children on playgrounds, identify key factors of destruction of products. features, topography of wear, frequency of cleaning from dirt, method of drying, etc. Thus, it can be argued that the shrinkage of fibrous systems depends on a sufficient number of factors that can affect simultaneously and comprehensively, and therefore this process should be classified as multifactorial and difficult to study, as the evaluation method used today is insufficient informative. The maximum allowable norms of such indicators as breaking characteristics up to (-15%) have been established; air permeability coefficient up to (-15%); abrasion resistance on the plane up to (-30%); thickness up to (+20%). The recommended method has been tested experimentally. Evaluation of changes in physical and mechanical characteristics of samples from the impact of repeated processing in the washing bath of a new recipe, close to home, was performed after each wash cycle using informative indicators such as breaking force based on Po, (N) air permeability coefficients Kp (dm3/m2·s) resistance of samples to abrasion in the plane Cs (cycles) and its thickness L (mm). The obtained results show the dependence of all indicators without exception on the number of washing cycles in soap and soda solution, with such as bursting loads of samples, their resistance to abrasion on the plane and air permeability decreases, and thickness increases compared to initial characteristics. The textile material should be considered resistant to the number of washing cycles in the soap and soda solution, which led to a change in at least one of the four criteria to the specified maximum allowable values.

Computer embroidery is one of the modern types of garment decoration. But in our country this industry is insufficiently studied. Instead, today there are entire associations of embroidery companies abroad, periodicals are published, special schools operate, international conferences are held, and Internet conferences on computer embroidery are organized. The article discusses the issues of improving the quality of applying an embroidered element to a textile material in order to increase the competitiveness of garments in the domestic market of goods and services. It was found that during machine embroidery, the most vulnerable point is the border of the “fabric-embroidery” system. If the embroidered pattern along the contours of the edge is characterized as a “straight line”, then the maximum value of the destruction of the samples at the warp occurs with tatami stitches, and weft with tatami stitches and zigzag. When the pattern is embroidered in the form of a circle, the destruction already occurs not only along the perimeter of the “arc line”, but also in the middle. If the embroidered pattern is a rectangle with wavy edges, in contrast to the straight and arc border lines in the system “fabric-embroidery”, the process of destruction occurs within, starting from the upper and then the lower contours. There is also a decrease in rupture characteristics at (S), (Z), and (T) –stitches. When studying the effect of embroidery needles on the physical and mechanical characteristics of textile materials, it was experimentally established that this process should be attributed to the destructive, the degree of which depends on their number, as well as the step and type of stitches. This is evidenced by the increase in the values of the coefficient of air permeability of the samples of materials and the decrease in the breaking indicators in comparison with the initial values. Thus, the research and their analysis shows that the degree of change in rupture characteristics, as a control indicator, primarily depends on the contour of the edge of the pattern, as well as the type of computer embroidery weave, but the greatest influence of these factors occurs when the geometry of the system boundary ” fabric-embroidery “is a straight line, and the smallest – a wavy line that does not contradict the mathematical model, the conclusions of which were used in the design of the embroidered element for children’s clothing (pants).
