- The article presents the results of a study of the technological properties of short flax and hemp fiber during processing on wool worsted equipment, which includes a set of technological machines for yarn production.A technology for producing flax-wool and hemp-wool yarns was developed and experimentally tested, including stages of fiber blend preparation, carding, and spinning according to the woolen system. A comparative analysis of the physical and mechanical properties of the resulting yarns was conducted, yarn breakage during spinning was assessed, and the main causes of technological defects were identified. Key factors affecting process stability and yarn quality were determined. Optimal parameters for preparing bast fibers were established, ensuring stable process performance, reducing breakage, and improving yarn quality. The relevance of the study is determined by the need to expand the raw material base of Kazakhstan’s textile industry and to rationally use local plant fibers in conditions of fine wool shortage. It was shown that processing bast fibers in blends with wool is possible with appropriate pre-treatment and optimization of processing regimes. The flax-wool blend demonstrated higher technological stability and improved strength characteristics. The results obtained confirm the potential for using bast fibers in woolen production and contribute to the development of domestic textile raw materials. 1
- The given article is devoted to the lexical and semantical peculiarities of the expression of spatial relations in the novel “The Way of Abay”. Considering the three-dimensionality (height, length and width) of the category of space, M. Auezov in his epic “The Way of Abay” scrutinizes the transfer of the state of the objective world in a static and dynamic position, also in a vertical, horizontal and volumetric plane with the help of lexical, lexical and morphological and syntactic language units. The results of the research of this work can be used in the preparation of a system of exercises in the preparation of textbooks and teaching aids based on a national-oriented approach to teaching any non-native language, including a foreign one. In this circumstance we see practical significance of the following research. 1
- The paper presents the results of a study on the storage of Aport apples using the MCP-1 preparation. The aim of the study was to evaluate the effectiveness of MCP-1 in the storage of the Almaty variety of Aport apples. The fruits were stored in a controlled atmosphere (CA) and under normal conditions, divided into control and experimental batches. Measurements were taken before and after storage, as well as after 14 days of aging at +23°C, simulating retail conditions. Despite initial violations of agricultural technologies and late harvesting, MCP-1 treatment had a positive effect: it helped to preserve the density and quality of the fruit, as well as reduce physiological disorders, especially under RGS storage conditions. The MCP-1 preparation not only effectively preserves the texture and respiratory stability of the fruit, but also significantly reduces losses caused by diseases, especially during long-term storage and subsequent aging at room temperature. This enhances the scientific and applied value of the use of modern growth regulators in fruit and vegetable storage technologies. The results obtained confirm the high effectiveness of MCP-1 in the storage of Aport apples and its significance for reducing losses during storage and sale, especially in the context of the Aport revival program in Kazakhstan. 1
- This article is devoted to the comprehensive evaluation of the design and quality parameters of products made from recycled denim fabric. The relevance of the study is обусловлена increasing interest in sustainable development and the rational use of textile waste in the modern light industry. The study examines clothing, accessories, and interior items created from secondary raw materials obtained from production waste and post-consumer denim materials. Various design solutions were applied in the development of the samples, including patchwork techniques, appliqué, and the use of fibrous filling materials. The evaluation of the samples was carried out based on a set of indicators including strength characteristics, the ability of the material to retain its shape, wear resistance, aesthetic properties, and ergonomic parameters. The analysis was performed using standardized testing methods and comparative analysis. The results showed that the use of recycled denim raw materials up to 50% in the material composition does not lead to a significant deterioration of the main quality indicators of the products. On the contrary, the use of creative design solutions increases the aesthetic attractiveness of the products. In general, it was found that products made from recycled denim have sufficient performance characteristics and can successfully compete in the modern market of environmentally oriented textile products. 1
- This article is devoted to the development of methodological approaches to wetsuit design based on the classification of water sports. The goal of this research is to create innovative wetsuits adapted to the specifics of water sports, increasing reliability and protective properties, while improving comfort and performance. The subject of the study is the "person-wetsuit-aquatic environment" system, with a particular focus on protecting the wearer from external factors by developing rational variants of wetsuit components, taking into account ergonomics and the dynamic conformity of the product. The article proposes a systematic classification of aquatic sports, taking into account the nature of the aquatic environment, the degree of its control, temperature parameters, and the requirements for protective equipment. A model for the combination of the type of sports discipline and the characteristics of wetsuits (neoprene thickness, design, and mandatory application conditions) has been developed. Special attention was paid to the water sport "slalom" as a sport with maximum hydrodynamic variability and increased thermal protection requirements. The dependence of equipment selection on temperature ranges, flow velocity, and wind conditions has been substantiated. The presented classification can be used in the development of new types of wetsuits with enhanced protective properties, as well as in athlete training, regulatory requirements, and improvement of training logistics. 1
- This research paper focuses on the diagnostics of a lockstitch shuttle sewing machine using the TYPICAL GC6150 as a case study. In modern garment manufacturing, sewing machines operate at high speeds, which requires precise phase synchronization of the main working mechanisms, including the needle, shuttle, thread take-up lever, and fabric feeding mechanism. Any disturbance in phase relationships may result in stitch skipping, thread breakage, unstable seam formation, and accelerated wear of machine components, ultimately reducing productivity and operational reliability. The study proposes a diagnostic method based on the combined use of micro-video monitoring and the construction of working cycle cyclograms. Micro-cameras enable visual observation of fast dynamic processes occurring in hard-to-reach areas of the sewing machine without complete disassembly. Video recordings are analyzed frame by frame to identify key diagnostic events and determine their time and phase parameters relative to the angular position of the main shaft. Experimental cyclograms derived from the video data make it possible to detect deviations from standard operating conditions at an early stage. The proposed approach improves diagnostic accuracy, reduces maintenance and adjustment time, enhances machine reliability, and ensures stable sewing quality in industrial production environments. 1
