Horach O. Scientific development of innovative technologies for obtaining technical textiles from oil flax fibers for various functional purposes

The object of research is the process of modification of oil flax fibers, suitable for the creation of technical textiles for various functional purposes. The purpose of the research is the scientific substantiation of the creation of technologies for obtaining technical textiles on the basis of modified oil flax fiber with adjustable technological and operational properties. Research methods - experimental-calculated standardized research methods using modern methods of theoretical and experimental research, current standardized methods for determining the physico-mechanical and physico-chemical properties of flax oil. For the first time, an important scientific and technical problem of modification of oil flax fibers, suitable for use in the production of technical textiles with certain physical, mechanical and chemical properties, has been solved. Regularities of change of a complex of physical-mechanical and chemical properties of fibers of oil flax which provide their suitability for use in production of technical textiles of various functional purpose are established. The criterion characteristics of oil flax fibers are determined, which determine the choice of parameters and modes of technological process of mechanical processing and modification of raw materials for the production of technical textiles. A methodology for modifying oil flax fibers has been developed in order to change their physical and mechanical characteristics and ensure suitability for obtaining technical textiles for various functional purposes by optimizing the modes and parameters of machining. As a result of mathematical processing of data on input characteristics of fibers of oil flax the physical and mechanical indicators providing their use as fillers during formation of composite materials are defined. Physico-mechanical and chemical properties of oil flax fibers as fillers for composite materials based on thermosetting resins are determined. The main reasons for the low wettability of the bast and the lack of adhesion to the polymer matrix, which are associated with the anatomical structure of the flax oil. A new oxidative method of boiling flax oil was used to remove cutins and inlays, which increased the adhesion of fibers to thermosetting resins. Field of use - textile industry, production of nonwovens and composite materials, research institutions, educational institutions.
