The object of research: ultrasonic processing technology of textile materials. Investigated problem: increasing the degree of splitting of complex hemp fibers due to the effect of the mechanism of ultrasonic cavitation on them. The main scientific results: The article shows the potential of textile production to ensure the environmental friendliness of textile products, and the development and implementation of new eco-technologies of physical and mechanical cottonization of hemp fiber is important in this. Analysis of existing methods of cottonization and structural features of hemp fibers has led to the conclusion that the destruction of cellulose satellites in complex fiber can be considered as a process of purification from impurities, since the technologies for purification of substances in the aquatic environment by ultrasound now are widely used. Therefore the process of cottonization of hemp by technology of ultrasonic treatment was used in this investigation for the first time. The basic principle effect on the textile material what placed in the liquid are the hydroacoustic effects formed by the collapse of cavitation bubbles in the contact zone "liquid-material". Experimental studies of the geometric characteristics of the obtained hemp cottonine were carried out, and the effectiveness of the effect of ultrasonic vibrations on the change of the structure of hemp fiber was confirmed. Due to the removal of inlaid substances under the action of cavitation, the complex fibers of hemp were split, as a result of which the range of variation and the absolute value of their length and linear density were decreased. The scope of practical use of the research results: textile enterprises of deep processing of bast raw materials into technical and household yarns. Innovation technological product: technology of ultrasonic cottonization of hemp fibers.

Violation of industrial safety rules during the operation of offshore facilities for the production, storage and transportation of the hydrocarbon raw materials leads in the most cases to pollution of the marine environment with oil and its components. The works on localization and elimination of such pollution are carried out with the help of vessels of the technical support fleet and booms. When developing oil spill response plans at such facilities, a calculated determination of the technical characteristics of vessels and booms is required that are sufficient to carry out the planned activities. The basic design principles for determining the towing capacity of the technical fleet vessels involved in the localization and elimination of oil and oil product spills by trawling methods are given in the article. The calculation is based on theoretical studies performed by the authors of the physical processes occurring during the movement of objects of a mobile trawling order in the sea area. The results obtained during the course of theoretical studies were confirmed by the experimental studies carried out by the authors personally using the real pieces of equipment in the actual development of tasks for training spill containment by trawling. As a result, the empirical dependencies were obtained and experimentally confirmed, which can be used to calculate technical characteristics of the ships as part of the mobile orders and anchor systems as part of stationary orders intended for the localization and elimination of oil pollution. These results can be used, among other things, for the calculated substantiation of the technical characteristics of the technical fleet vessels designed to ensure safety of the offshore facilities for production, storage, and transportation of the hydrocarbon raw materials.

Object of research. The article investigates the cutting forces when grinding martensitic-aging steels with highly porous grinding wheels. The problem to be solved is the regularities of the change in the magnitude of the cutting forces when grinding maraging steels with highly porous CBN wheels. Main scientific results. The studies were performed on martensiticaging steel H8K18M14. As a result of the experiments, it was found that when grinding wheels made of materials such as electrocorundum, CBN (borazon) and diamond, a significant role is played by the values of the cutting force, which increase during processing. During the experiment it was found out: the cutting forces Py and Pz in the width of the allowable modes, which are most often used in circular and flat grinding, can reach the following values: with the structure of the wheel 26 come to values from 2.714N to 30.721 and with the structure of the wheel 40 come to values from 2.49N to 28.185N. Reducing the grain size of the wheel, let’s obtain the effect of increasing the energy costs of the grinding process, by increasing the magnitude of the cutting forces. If to compare the cutting forces that occur when grinding different wheels, it is possible to note the following: in comparison with electrocorundum wheels when using wheels with KNB cutting forces are reduced by 20-25 %, and when grinding with diamond wheels, the effect of cutting forces is reduced by 25 - 30 %. When grinding with highly porous wheels, the cutting force is 15-20 % higher than when grinding with wheels of normal porosity. The area of practical use of research results-grinding technology for maraging steels. Innovative technological product – relationship between processing modes and the magnitude of cutting forces when grinding maraging steels.

Object of research: technology as a component of human social life in the context of the postmodern era. Investigated problem: determination of the features of the influence of technological processes on a person of the postmodern era, as a result of which the natural is replaced by an artificial one and the images of both man and the Earth change. Main scientific results: the study of the contradictions of the process of technologization in the postmodern era made it possible to determine the transformation processes taking place in the life of a person and society. This defines social reality, represented by various markers, among which technology is gaining in importance. The latter act as a composite, which provides new opportunities for determining the relationship between the elements of the "world - man - culture" system. It is not only about the emergence of new human figures, among which the technological man (Homo Technologicus) occupies a prominent place, but also the emergence of a new image of the Earth, where the natural is replaced by the technological. The scope of practical use of the research results: the research results can be used in teaching normative courses "Philosophical Anthropology", "Ethics", "Sociology" for students and undergraduates, graduate students of humanitarian and natural faculties. Innovative technological product: the plurality of existing technologies (economic, medical, educational, humanitarian, etc.) destroys the new European concept of culture and man, which were provided within the framework of the monoparadigm. The anthropological dimension of technology testifies that the latter are beginning to act as a condition for human expansion. This situation has a significant impact on the existentials of human existence. The scope of using the innovative technological product: the intensive technologization of the last decades not only provokes environmental risks and changes the state of the Earth, the natural reality of the Earth is replaced by an artificial one, which allows to conclude that the Earth is formed by a technological one.
