The scientific basis for the use of electro-bit treatment in wool finishing technologies is brought up in this paper. A number of new fundamental results are obtained that contribute to a better understanding of the processes and mechanisms of action of the electro-bit nonlinear volume cavitation on the structure of the wool fibers and dye solutions.
The scientific credence by using electro-bit nonlinear volume cavitation for the wool preparing is given as a way to intensify the natural pollution removal of wool fiber and in the process of wool acid dyeing as a way to impact on the environment of the dyeing system. It is determined that the mechanism of intensifying action of the electro-bit treatment lie in destruction of the fatty film on the fiber surface that increases the rate of its subsequent removal and activation of acidic dye solutions due to the destruction of water clusters, thereby increasing the diffusion mobility of dye solution particles. It is proved that formation of a complex of high physical and chemical, physical and mechanical, technological and operational properties of wool fibers is possible due to the influence of the main acting factors of electro-bit nonlinear volume cavitation on the surface and internal structure of wool keratin.
The practical significance of work lies in development of new eco-friendly, energy-saving technologies to produce high-quality wool raw materials using electro-bit treatment at washing and dyeing stage of wool fiber. The results of studies show a decrease in the cost of finished products, improvement of technical and economic indicators, qualitative change in production through the use of high technology that was confirmed by approbation of the developed technologies at production site.
The developed composition of surfactants for wool scouring is applied on the factory floor. The economic effect measured in 2013 UAH was as follows: application of scouring process – 2051,1 UAH for 1 ton of scoured fiber; application of dying process- 2405,8 UAH for 1 ton of dyed wool.
