Energy evaluation of deformation processes of polymer materials
DOI: 10.46418/0021-3489_2023_61_03_01
Energy estimates of the processes of relaxation and creep of polymers are considered. Polymeric materials have pronounced rheological properties, including: a flexible chain structure of macromolecules in an oriented state and having an amorphous-crystal- line structure at the supramolecular level. According to modern views of structural physicists, it is at this level that the rheological properties of polymers are formed - as a combination of elasticity, viscoelasticity and plasticity.

The analysis of the current state of the theory and practice of building digital twins is carried out, the possibility of using a hierarchical approach, which involves the development of a dynamic copy of clothing according to the principle of nesting, is substantiated. The applicability of mathematical modeling methods in the construction of digital twins of clothing sets is substantiated. Approaches to the numerical modeling of clothes are generalized, it is established that the process of modeling various structural elements proceeds according to similar methods and using qualitatively homogeneous tools. An approach to solving the problem of building digital twins of clothing is proposed.

Agricultural and paper waste as a source of high-quality nanocellulose - a review
DOI: 10.46418/0021-3489_2023_61_03_15
Agricultural and paper waste can be applied to produce new cellulosic materials, including nanocellulose (NC), which is in a high demand in the biomedical field, energy, environmental protection, it is widely used as an additive to enhance strength in various composite and smart materials. The development of alternative sources for the extraction of NC opens up new opportunities for sustainable and innovative production based on the efficient use of resources and reducing the anthropogenic impact on the environment. In order to isolate NC, firstly, plant agricultural and paper waste are pretreated to remove the impurities using alkali solutions (2-17.5 %) and bleaching (oxidation) with NaOCl or H2O2. In some cases, the pretreatment stage is skipped, that simplify and reduce the cost of the production process, but the quality (chemical purity, degree of crystallinity, particle size) and the yield of NC decline. The main stage of obtaining NC is carried out using acid hydrolysis in concentrated solutions of mineral acids. To obtain NC with higher crystallinity values, it is recommended to use higher concentrations of acids and/or elevated temperatures and pretreatment with diluted NaOH solutions. Even from waste paper of low grades (newsprint, cardboard) it is possible to obtain NC with a high degree of crystallinity (up to 94.8 %) and a particle size of up to 4 nm. Thus, agricultural and paper waste is a promising raw material for obtaining NC, which is not inferior in quality to NC isolated from wood pulp.

Synergetic intelligent systems of fine arts and design: theory and practice of designing metaphors of physical phenomena and bioforms of macromycetes in artistic images of jewelry design objects
DOI: 10.46418/0021-3489_2023_61_03_17
The relevance of this action lies in the use of systems of wildlife, represented by plants, animals and fungi (Fungi, Mycota), which are an independent giant world with about 60 thousand species. The significant variety of shapes and colors of the fruit bodies of large mushrooms is a significant reason for the creative modeling of artistic images in the visual arts and design. A certain typological correspondence of strange attractors sets figurative parallels connecting the geometry of the forms of physical processes of the chain reaction of fission of the nuclei of uranium atoms, which has a mushroom shape, with the semantics of cognitive technologies in the theory of fine arts and design.

Experimental studies of chemical factor influence to polimeric-textile fabric
DOI: 10.46418/0021-3489_2023_61_03_19
The article analyzes the properties of a polymer-textile material after chemical exposure. Petroleum products, acids, solvents and mechanical forces are factors of environmental impact on the worker. Details of the protective overlays of the workwear are located in the places of pollution, i. e. in the elbow area on the jacket and in the knee area on the trousers. We have done material research before the workwear design. The time of protective action from sulfuric acid, the swelling properties of a polymer-textile material under the influence of a solvent, the change in linear dimensions after treatment with a solvent, the physical and mechanical properties of a polymer-textile material after simulated pollution and cleaning with a solvent «kerosene» were studied. In the first experiment, sulfuric acid is used to evaluate the acid-proof property and the effective protection time of a workwear. In the next experiment, the solvent is applied to the polymer-textile material to analyze the swelling properties, as well as changes in linear dimensions. In the last experiment, the physical and mechanical properties of a polymer-textile fabric are investigated after the sur- face of the polymer-textile material has been coated with a petrochemical product and then cleaned by immersion in a cuvette of kerosene. It was obtained that the protective properties of the material are preserved after exposure by sulfuric acid and after a bitumen-based mastic smear and cleaning by organic solvent. As a result of experiments it was found the breaking under tension index changes little (about 6 %) when we use kerosene as an external influence on the material.

The article presents the results of a study of the influence of the temperature of the heating plates of a thermal press and the duration of heating during the formation of a multilayer material for clothing for outdoor activities on its main consumer properties. The package of materials is formed from the top layer - cotton-polyester fabric, the lining - a two-layer knitted fabric with the insertion of functional threads (with the Quick Dry moisture management function, Soft microfilament, Thermo thermoregulating thread). As a result of the research, it was found that the presence of functional threads in the structure of the lining layer of a multilayer material affects its functional and consumer properties, this will make it possible to form a package depending on the requirements for the final product. Rational technological regimes for the formation of a multilayer material with high sorption and heat-shielding properties are recommended. The modes of thermopressing providing the maximum durability of connection of layers are established.
