DOI: 10.46418/0021-3489_2023_60_02_01
A method is proposed for determining the strength resource that ensures the safe operation of technical fabrics, taking into account various climatic zones, with various modes of intermittent or continuous exposure to light weather. The method is illustrated by examples of assessing the strength resources of seventeen variants of fabrics subjected to natural light-weather effects in the Leningrad, Kursk and Rostov regions and predicting their resources in four other regions of the country - Moscow, Krasnodar, Khabarovsk, Astrakhan with intermittent seasonal operation schedules.

Conducting an assessment of the functionality of polymeric textile materials in order to increase their competitiveness
DOI: 10.46418/0021-3489_2023_60_02_06
The article describes a method for assessing the functionality of polymeric textile materials in order to increase their competitiveness. This assessment of the functionality of polymeric textile materials is carried out on the basis of mathematical modeling of their viscoelasticity. In this case, one of the generally recognized variants of mathematical modeling of the viscoelasticity of polymeric 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 the reduced time.

Increasing the Accuracy of Mathematical Modeling and Prediction of Deformation Processes in Polymeric Textile Materials
DOI: 10.46418/0021-3489_2023_60_02_07
The article deals with the issues of improving the accuracy of mathematical modeling and predicting the deformation processes of polymeric textile materials, which are proposed to be carried out on the basis of the corresponding integral criteria for the adequacy of modeling the viscoelasticity of these materials. The criteria represent an estimate of the magnitude of the deviations of the values of the integral convolutions of the nuclei of relaxation and creep of polymeric textile materials from the theoretically substantiated single value. The less the value of the specified integral convolution differs from a single value, the more adequate the developed models of relaxation and creep, and, therefore, the corresponding numerical prediction of viscoelastic-plastic processes of the studied polymeric textile materials will be more accurate.

The range of values of the thickness of the sole and the modulus of elasticity of the plantar material, within which the puncture resistance ensures the safety of shoes, has been established. The results obtained will allow you to choose plantar materials and the thickness of the soles that ensure the safe operation of shoes in conditions of possible contact with sharp objects.

The calculation of weft-knitted plated fabric dimensional parameters
DOI: 10.46418/0021-3489_2023_60_02_13
The models of relaxed plain-knit structure proposed by previous workers suffer from the assumption that the loop is formed by a single yarn. However the majority of the knitted fabrics are manufactured from the two yarns. If the mentioned yarns are different the knitted structure usually defined as plated stitch. In this paper plated stitch loop model is present and analyzed as system of localized forces and couples acting in the loop at the interlocking points. The calculated knitted loop dimensional parameters are compared with the experimental data.

Development of cultural traditions (Kuban)
DOI: 10.46418/0021-3489_2023_60_02_18
Education of youth on cultural traditions is to create conditions under which, in the process of learning, children study the cultural heritage of their region. The upbringing of young people on the traditions and customs of their region acquires particular urgency. In our Krasnodar Territory, young people study the traditions, customs, culture inherent in the Kuban Cossacks, who carry the amount of knowledge and experience that has been tested for centuries, the culture and way of the ethnic group. Works of arts and crafts and folk art, evoking aesthetic emotions, convince, convey to the consciousness of the younger generation the need for a respectful, careful attitude to the cultural heritage of the region where they live. In order to form an integral system of knowledge, skills and abilities that meet the modern requirements of the future life of students, it is necessary to give in the lesson the knowledge that will be necessary not only for society, but also for the students themselves. The study of folk art, collecting samples, mastering the technology of manufacturing traditional products is one of the most interesting and most fruitful types of work in education. They not only acquire a certain amount of knowledge and skills, but also systematically get acquainted with the history of their people with its best examples of craftsmanship. Raising the younger generation on the folk culture of the Kuban is a necessary emotional, inspiring beginning in relation to the individual to the reality around them, so that they learn and transform the world around them according to the laws of nature and beauty. The folk culture of the Kuban Cossacks directs and is capable of activating the worldview of a person. A people without knowledge of its culture, traditions, and customs is deprived of historical memory.
