Research results and their novelty. For the first time: 1) methods of obtaining textile materials with barrier properties for protection with application of fundamentally different nanotechnological approaches and mechanisms for their obtaining have been developed; 2) for the first time a method for the formation of nanostructures according to the mechanism of in situ in the I methods of chemical technology of textile materials was developed; the method of volume of a fiber matrix in the process of its chemical modification, which envisaged the localization of magnetite nanoparticles in the fibric structure as in a nanoreactor; 3) for the first time the regularities of the influence of the synthesis conditions on the size of the magnetite nanoparticles and the magnetic properties of the textile material have been established; 4) the method for obtaining antibacterial, fungicidal and electroconductive properties was developed for the first time by applying layers of colloidal particles to the surface using the mechanism of heterocoagulation; 5) for the first time, based on theoretical and experimental researches, physicochemical regularities of nanotechnologies for the creation of textile materials with a complex of barrier properties have been established; 6) for the first time on the basis of the conducted research the theory of describing the process of multilayer reverse heterocoagulation of nanoparticles was created due to their self-organization on the surface of the substrate using the BET approach, provided that the nanoparticles are applied with the use of surfactants. 7) for the first time on the basis of experimental data on nanotechnologies for the creation of protective textiles, the theory of thermodynamics of the coloring process with nanoparticulate dyes with an antibacterial component is described. Practical significance: developed methods for the creation of time-stable magnetic textile materials of different raw materials by synthesizing nanomagnetites inside a textile material that acts as a nanoreactor; An express method for evaluating the protective properties of the created textile materials due to the intense absorption of microwave energy by nanoparticles of magnetite has been developed: the methods of providing the textile materials of bactericidal and fungicidal properties using heterocoagulation in the framework of nanotechnologies are developed. Main constructive, technological and technical and operational characteristics and indicators.When carrying out the GDR, 3 patents were obtained for the utility model (1 - Pat. (UA) 111395 C2; 2 - Patent 113268 (UA); IPC B01J 39/00; 3 - Patent 116895 (UA); IPC G01N 27/72; G01N 33/00, G01N 33/383). The degree of implementation: the work is fundamental. The results of the research work were used in updating the lecture course "Chemical technology of textile materials", for students of educational qualification level, bachelor in the direction of preparation. 6.051601 - Technology and design of textile materials. Also, in this context, 4 master's degree qualifications are protected on the theme of GDR; 1 candidate's dissertation (Romankevich Ya.O.) and 1 doctoral dissertation (Garanina O.O.) were completed and defended. Interconnection with other works: in order to obtain time-stable magnetic textile materials, the magnetite nanoparticles must be localized within the fibrous fibers from which the textile material is composed. In the process of studying this problem it became clear that there are more general problems of creating magnetic nanoparticles in the fiber environment, which would provide spatial placement, size and other characteristics of nanoparticles and would determine the properties of the obtained textile materials with barrier properties. The use of nanotechnology for the purpose of depositing antibacterial and fungicidal components on the surface of fibers by the mechanism of heterocoagulation is practically not investigated. The general theories of the creation of dispersions and heterocoagulation of nanoparticles on the surface are qualitative in nature, which does not allow to determine the parameters of nanotechnology: heterocoagulation of particles on the surface with the formation of a layer that gives the textile materials antibacterial and fungicidal properties. In this GDR, textile materials with barrier properties using nanotechnology as a process are developed for the first time and have no analogues. Recommendations on the use of the results of work: knowledge of the physical and chemical laws of nanotechnologies, the creation of textile materials with barrier properties, has allowed to develop new methods for obtaining protective textiles. The obtained values ??of saturation magnetization (Ms = 2 ? 10 A / m2 / kg) indicate that the magnetic materials are technologically acceptable for the production of a prototype protective suit, for example, to protect against the influence of the electromagnetic fields of the radar station staff, to protect the personnel of the military units and military communications and communications from microwave radiation. In the manufacture of screens of textile materials the undoubted advantage is the high technological level of such products, which, together with the high production of modern equipment and the relatively low cost of raw materials and manufacturing process, makes the prospect of using nanotechnology to obtain textile materials with magnetic properties to create flexible, durable and air permeable screens and absorbers of electromagnetic radiation, which contributes to the expansion of the range of technical textiles from the protection We have properties. The need for the use of textile materials and products with bactericidal and fungicidal properties in emergencies is due to the fact that when they are used, human protection from external infection is attained, the risk of developing an infectious process on the skin is reduced due to autogenous infection and interruption of the transmission of fungal and pustular infection in environment. Field of application: textile products of technical and departmental purposes with special properties for protection. Economic efficiency: when replacing metallized fibers, in the manufacture of which are used complex technological processes associated with the use of special equipment, the use of created magnetic textile materials provides significant savings. Conclusions, suggestions on the development of the research object and the expediency of continuing the research: it is expedient to further develop developments on this topic, the indicative subjects - applied research to ensure the implementation of developments in the industry.
