The dissertation is devoted to research and solution of a current but insufficiently studied issue concerning improving the scientifically cogent selection of textile materials for hospital products. The international and domestic experience in the development of garments for patients undergoing treatment in inpatient facilities have been analyzed, which showed that currently there is no scientifically cogent method of new materials confection for ergonomic, adapted to the operating conditions of hospital textiles. The influence of performing characteristic diagnostic and medical manipulations on placement of functional elements in innovative hospital textiles has been revealed. The basic medical and biological, functional and technical requirements to materials for their production have been established, the factors determining the necessary operational characteristics, sensory and thermophysiological comfort have been revealed. The topography of location of special functional inserts with specified properties in places that for comfortable use require increased moisture absorption, removal of excess vapor and moisture, ventilation and rapid drying, increased smoothness or vice versa, surface roughness, appropriate damping characteristics has been developed. Fabrics and knitted fabrics, which according to regulations are approved for use in medical products, as well as innovative multifunctional textile materials of different raw materials and structure, have been selected as objects of study for comparative analysis. The nomenclature of material quality indicators has been expanded including indicators that reflect the specific operating conditions of products - moisture content determined by the pressure of the lying human body, kinetics of drying moistened material at human body surface temperature, pollination and cleaning of the material surface, tangential resistance to fabrics moistened with standard ‘sweat solution’. We have proposed an environmentally sound, affordable and inexpensive method of processing cellulose-containing hospital products to protect patients from the negative effects of ultraviolet radiation. Natural aluminosilicate haloisite nanotubes were selected for nanomodification, which are approved for use in biomedical materials and sanitary products. It has been found that the use of aids helps patients with limited motor functions to overcome severe physical barriers during forced movement, greatly simplifies various manipulations and is very helpful to those who care for the patient. The model of friction of textile materials has been developed, the use of which makes it possible to adjust the roughness or smoothness of the surface when designing their structure. Fabrics with the optimal combination of surface roughness and strength for products intended for movement, fixation and transport of immobile patients and the wounded have been made.
