Investigation of the influence of textile materials structure of different raw materials for hospital bedding on the ability to provide sensory comfort and durability. 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 ALAMBETAinstrument, 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. 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 appearednap, 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. 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. A new range of textile materials for bed linen has been proposed, taking into account the requirements of sensory comfort and durability.
