Qualitative assessment of the functionality of polymer textile materials
DOI: 10.46418/0021-3489_2024_65_01_01
The article describes a method for conducting a qualitative assessment of the functionality of polymer textile materials in order to increase their competitiveness. This assessment of the functionality of polymer textile materials is carried out on the basis of mathematical modeling of their viscoelasticity. At the same time, one of the generally accepted options for mathematical modeling of viscoelasticity of polymer materials is considered, based on the analytical approximation of experimental “families” of relaxation and deformation curves by normalized relaxation and deformation functions on a logarithmic scale of reduced time.

Development of a mathematical model of the process of shape formation of a surface from draped materials
DOI: 10.46418/0021-3489_2024_65_01_02
The article discusses the issues of shaping the surface which is made from draped textile materials. Analysis of existing approaches to this problem was carried out. Original approach to mathematical modeling based on a set of principles such as multifactoriality, similarity, continuity and local indefiniteness is proposed. The main factors determined by the shape of the surface have been identified. We consider local indefiniteness of the shape as variable speciality which are conditioned by indefinite external and inner factors. The mathematical model which allows us to use continuous transformations to design a given form of clothing on a human figure has been developed. Taking into account physical, mechanical and geometric properties of the materials we based our analysis of developed model on some original experiments and computer simulation of textile materials.

Comparison of loss functions in recognition based on podometric images
DOI: 10.46418/0021-3489_2024_65_01_04
When using neural networks in solving regression problems, standard loss functions are most often used: the average square of error, the average absolute deviation, the average percentage of absolute error and the average square of logarithmic error. However, in some situations, they do not allow or make it very difficult to achieve the desired result. In this article, we examined the effect of user-defined loss functions on speeding up the learning process and convergence to the desired result.

Research of the heat protective properties of multilayer materials for workwear using functional threads
DOI: 10.46418/0021-3489_2024_65_01_10
The article presents the results of a study of the thermophysical properties of multilayer materials in the structure two-layer knitted fabrics made of functional polyester threads Quick Dry 18.7 tex (f144), Soft 16.7 tex (f288), Thermo 16.7 tex (f96 ). An analysis of the change in the temperature field of a multilayer package during heating was carried out, and the cooling rate of multilayer materials was calculated. It has been proven that the use of Soft, Quick, Thermo threads in the structure of a knitted fabric allows one to reduce the cooling rate of the multilayer material, which is explained by the presence of numerous small air pores, as well as hollow axial channels in the Thermo thread. A comprehensive assessment of the properties of multilayer materials was carried out in terms of total thermal resistance and air permeability. It is recommended to use bags containing Quick and Thermo functional threads in the structure for the manufacture of workwear with improved heat-protective and hygienic properties.

Designing orthopedic insoles profiling elements using neural networks
DOI: 10.46418/0021-3489_2024_65_01_14
Based on an analysis of sources, a concept for the manufacture of in-lay orthopedic products using a neural network is proposed, the stages of the design process are described, and problems that require solutions are identified. The article contains a methodology for designing orthopedic insoles and features of their manufacture using digital processing machines and 3D printing technology. The issues of using materials permitted for use by the properties of the intersole layer are addressed. During the research, experiments were carried out on images from the podograph, and different neural network structures were tested. It was revealed that with the help of such an architecture it is possible to determine the position of the feet in the podograph image, taking into account anomalies with a deviation of up to 84%. The main focus is on visualization: selection of appropriate tools (programming language and libraries), development of the application interface. The article describes the features of libraries for working with 3D objects - numpy-stl, pymesh, pyvista, as well as for the graphical interface - PyQT5, TKinter, Pyside, PyQT5/PySide+QML, Kivy, PySimpleGUI, wxPython. The selection of the most suitable tools for solving the problem was carried out, the program code was developed and a visualization (interbody layers) of the profiling of the insole elements was provided. The scientific novelty lies in displaying the position of the feet on a podograph image using a neural network, calculating their sizes, conditions and zonal pressure. Based on the results of the results and the expert's recommendations, the program selects several elements, ensuring the construction of reasonable insoles designs. The proposed concept for the development of in-lay orthopedic products makes it possible to automate the process of their manufacture and reduce production time.

DOI: 10.46418/0021-3489_2024_65_01_22
The concept of historical leather includes leather products made no earlier than 50 years ago, since such a requirement is imposed on objects of historical and cultural heritage, antiques. Over time, the skin loses elasticity, firmness, becomes rigid and brittle, loses its qualities and collapses. As a result, the product loses its appearance and shape, the skin darkens, and the exhibit becomes close to loss. The task is to determine the optimal composition of the fattening emulsion, which makes it possible to give the skin plasticity and at the same time has preservative properties.
