AbstractThe application of X-ray fluorescence to the qualitative and quantitative analysis of chemically modified cotton textile materials is described. The scope and flexibility of the technique have permitted the determination of more than 20 elements with, greatly reduced elapsed time compared with the corresponding spectroscopic or wet methods. Precautions to be observed in preparing standards are discussed. Results of the analysis of typical modifications and their significance in the development of cottons for specific uses are described.

Resistance of tear is an important characteristic of textile materials, especially for fabrics used for personal protective equipment. In this study, a constant force is applied to tear the fabric specimens to obtain the del-zone theoretically. The strain-stress curve for a single yarn is obtained from experiment, and the del-zone is determined by an ancient Chinese algorithm. This combination of ancient Chinese algorithm and actual tearing behavior of woven fabrics provides a noval analysis approach of tearing performance of textile product theoretically.

The object of research of the article is the methodological and technical support for the process of studying the characteristics of ergonomic properties of materials used in the manufacture of garments, and the subject – the method for the determination of textile materials’ air permeability. The aim of the work is to simplify the method for determination of fibrous materials’ air permeability and to expand the technological capabilities of its instrument base while increasing the flexibility of the control procedure. To achieve this goal, the tasks related to the analysis of existing methods and technical means, and the development of a new method for determining the air permeability of textile materials were solved. The principal difference in the developed method is the possibility to conduct studies on the air permeability of textile materials at different levels of pressure drop on both sides of the sample, and not only in accordance with the standardized requirements. An additional advantage of the method is the possibility to create an online electronic database on the properties of materials. In comparison with analogues, the proposed method for the determination of air permeability ensures the accuracy and reliability of the data obtained, as well as facilitates the testing process by automation.

Urgency of the research. The main functional property of children's outerwear is a heat-shielding property. The research of the heat-shielding properties of natural and synthetic fillers for children's outerwear production is quite multifaceted, complex and insufficiently studied question. This is due to the fact that for the manufacture of children's outerwear new fabrics for the top and lining, as well as fillers of various materials are used. Target setting. Determination of the optimal parameters of the heat-shielding properties of natural and synthetic fillers for children's outerwear production is an important task, since the greatest value of clothing is for the processes of heat exchange of the human body with the environment and to ensure normal thermoregulation. Actual scientific researches and issues analysis. Considerable attention has been paid to the prediction of the heatprotective properties of winter clothing or its construction, the substantiation of the choice of a package of materials for the manufacture of children's outerwear, mathematical modelling of the heat transfer through textile materials and to the physical model of thermal resistance determination. Uninvestigated parts of general matters defining. The heat-shielding properties of natural and synthetic fillers for the outerwear of children are practically not studied, and the calculations of the optimal parameters of these properties are fragmentary. The research objective. to determine the optimal parameters of the heat-shielding properties of natural and synthetic fillers for children's outerwear production. The statement of basic materials. It was found that the heat-shielding properties of children's jackets with feather-down and synthetic textile filler depend on the type of filler, thickness, surface density and breathability of the clothing package. Conclusions. Children's jackets with feather-down filler with a smaller thickness have the lowest level of breathability, which provides them with the best heat-shielding properties. The higher level of breathability inherent in a children's jacket with synthetic textile filler with a significantly greater thickness of the package can provide high levels of the heat-shielding properties. Mathematical equations to determine the optimal parameters of the heat-shielding properties of natural and synthetic fillers for children's outerwear production are suggested.
