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.
Виявлено стан дослідженості наявності та характеру прояву українських національних рис у сучасному образотворчому мистецтві. Зазначено основних авторів, які працюють над цим питанням та сферу їх наукового пошуку. Акцентовано увагу на тих рисах, що науковці вбачають у творчості досліджуваних ними митців або течій. Виявлено основні національні риси у сучасному українському образотворчому мистецтві (в його стилістиці, тематиці, символіці, зв’язку з традиційним мистецтвом). Зазначено переважання мистецтвознавчого контексту існуючих досліджень, у зв’язку з чим поставлено питання про необхідність проведення культурологічного дослідження проблеми для створення цілісного уявлення про наявність національних рис у сучасному образотворчому мистецтві України.
The research of different types of Ukrainian national women’s shirts of the Boykiv region at the end of the XIX and the beginning of the XX century about constructive-technological decisions and used colours of materials is carried out in the work. The main types of cut of national shirts of Boykivshchyna have been studied: shirt with shoulder inserts, tunic-like shirt, shirt with one-piece sleeves, shirt with coquette. The authors have developed a classifier of structural elements of the Ukrainian national shirts of Boykivshchyna. Based on the developed classifier, a massive of structural elements of Ukrainian national shirts of Boykivshchyna was formed, which contains information on types of shirt cuts, their silhouettes, length of shirts, types of sleeves by shape and length, types of collars and neck shapes. The proposed massive can be expanded and supplemented, provided that further research will reveal some more structural elements of traditional shirts. Using the structural elements of the massive, it is possible to create new models of modern women’s dresses, introducing them into mass production. Combining design elements, it is possible to create different versions of models of women’s dresses for implementation in multimodal flows. The results of research on determining the colour scheme of materials used for the manufacture of national shirts of Boykivshchyna are presented. It was determined that the most common colours were: blue, beige, white and burgundy. Colours such as red, black, brown, blue, and green were less common. RGB-parameters of shades of colours of materials which are offered to use at designing of the modern women’s dresses made in ethno-style are defined. According to the results of the research, sketches of three models of women’s dresses were developed. Model A of a modern women’s dress, made in ethno style, sewn in industrial conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
