Purpose. Investigation of the influence of textile materials structure of different raw materials for hospital bedding on the ability to provide sensory comfort and durability. Methodology. Theoretical and experimental investigations are based on the main positions of textile materials science. Sensory comfort and durability of textile fabrics were evaluated by thermal and mechanical properties. The measurement of thermophysical characteristics was carried out on the ALAMBETA instrument, the abrasion resistance was determined on a Pilltester type 14. The strength of textile materials, the tangential resistance, the flexural rigidity and the resistance of dyeing to dry friction were determined by standardized methods. Results. A comparative analysis of the sensory comfort of traditional textile materials for hospital bedding and fabric with bamboo fibers was carried out, which is determined by the mechanospecific sensations of skin receptors on the surface texture of the material, its roughness, stiffness, the feeling of cold or warmness when touching. Their thermophysical properties are determined, the evaluation of the feeling of cold or heat when touched is made according to the indicator "thermal absorption coefficient". By the method of an inclined plane the differences of the texture of dry and moisten studied fabrics was analyzed. The results of the wear resistance indicated that all fabric samples have high abrasion resistance; on part of the test specimens after 1200 cycles appeared nap, on mixed fabric – piles. The values of strength and bending stiffness were determined and the effect of 5 washing cycles on these indices was determined. The resistance of the dye to the action of dry friction of all investigated materials is 5 points. Scientific novelty. The comparative analysis of the values of the coefficients of thermal absorption made it possible to evaluate the feeling of cold or heat when touched, which coincide with the results of the provided organoleptic determinations. It has been experimentally proven that the assortment of cotton and mixed textile fabrics used now for bedding can be supplemented with bamboo fiber materials that provide a high level of sensory comfort and durability. Practical value. A new range of textile materials for bed linen has been proposed, taking into account the requirements of sensory comfort and durability. [ABSTRACT FROM AUTHOR]

Purpose. Determination of comfort properties of knitted underwear for sports and comparison of traditional and innovative underwear for thermal underwear. Methodology. The article provides an analysis of the modern range of textile materials for underwear, analyzes the latest developments in the design of thermal underwear. The modern methods have been used to determine clothing comfort and physical properties of textile materials. Experimental studies are based on the basic principles of textile materials science. Findings. Modern approaches to the design of sportswear are presented. The basic technological solutions of the “layered concept" of sportswear are considered. The main factors of the formation of a modern range of underwear for sports were analyzed. The main attention is paid to the most technologically advanced textiles, which are called "thermal underwear". The analysis of comfort properties of traditional and innovative underwear's, is presented on the example of CoolMax®. Originality. The data of thermophysiological and sensory comfort properties of textile materials of various structures and compositions has been systematized. It has been experimentally proved that the assortment of traditional textile materials that are used today for the manufacture of underwear cannot provide an appropriate level of comfort for sportswear. The hygienic properties of the CoolMax® fabric, which are due to the four-channel polyester fibers, are comprehensively characterized. Practical value. The feasibility of using CoolMax® for underwear has been proven. [ABSTRACT FROM AUTHOR]

Purpose. Analysis of existing textile materials used for electromagnetic radiation shielding, their systematization, and basic production methods are the main goals of this review. Methodology. The review of scientific literature and the systematization of the results in the field "textile materials for electromagnetic interference" are the main methods used for this research. Results. Shielding materials based on textile materials are widely used for protection against electromagnetic radiation (EMR) from existing electrical and electronic devices. Methods for imparting shielding properties to textile materials can be classified in two directions: surface treatment and fillers. The solutions used to add conductivity to textiles are very diverse and depend on the shield application. However, surface treatment is often time consuming and expensive. The introduction of fillers in the form of particles, fibers, threads and fabrics into the material are increasingly using to create electromagnetic shields. Textile shielding materials are made from conductive polymers, metal fibers (carbon, stainless steel, copper, etc.), metal wires, metal-coated threads or multifilaments. Generally, the electrical conductivity and shielding efficiency from EMI of all textile materials (woven, knitted, non-woven fabrics) are improved by incorporating metal fibers, metal particles or conductive polymers into them at different production stages. Scientific novelty. The detailed analysis of textile materials for shielding against electromagnetic radiation and of the research works in this field are presented in this review. The existing methods for producing textile shields are systematized by the authors. Practical value. It is a familiarization of a wide circle of specialists with the current state of the problem of protection against electromagnetic radiation. The main trends and prospects for the development of textile materials for electromagnetic shielding are identified as a result of this review. [ABSTRACT FROM AUTHOR]
