Studying the influence of continuous centrifugal mixers design features on their smoothing ability. The methods used are discrete elements, mathematical modeling and regression analysis. The paper considers five continuous centrifugal mixers designs with conical and parabolic rotors. The mixers design features are determined, allowing to change their smoothing ability. Mathematical models of the bulk materials particles movement inside each mixer have been developed based on the discrete element method. The considered mixers reaction to a step change of the key component amount is investigated. The transients parameters are calculated and the particles average residence time in the mixer is determined. It is established that the introduction of turbulizers in the mixers design increases the particles kinetic energy, which leads to a decrease in their residence time in the mixer. Moreover, the absence of a turbulizer leads to a decrease in the mixing intensity. It was also found that the most effective way to increase the mixer smoothing ability is the introduction of additional rotors. In terms of the technological and design parameters combination, the use of mixers with a conical rotor and a turbulizer is the most effective from the point of view for increasing the smoothing ability. On the discrete element method basis, the bulk materials particles movement models in continuous centrifugal mixers of five designs have been developed. The influence of the mixers design features on their smoothing ability and average mixing time is determined. The results obtained allow us to select the appropriate mixer design according to the specified requirements for smoothing ability.

Development of ecologically safe technology of finishing the textile materials using strawberry sepals extract and determination of influence for a mordant with salts from various metals on coloring quality. The technological parameters of the dyeing process by strawberry sepals extract were determined for linen, cotton, viscose and wool textile materials using pre-treatment with or without metal salts of Cu2+, Zn2+, Ni2+, Fe3+, Al3+. The color characteristics of the samples were determined using Adobe Photoshop CS6 software to evaluate the color quality. The resistance of the dyeing the textile materials to physical and chemical influences were determined by standard methods for textile materials. Ecologically safe technology of finishing the cellulosic and wool textile materials using strawberry sepals extract has been developed. The dyeing of textile materials made from cellulose fibers made it possible to obtain coloration from light to dark brown. After dyeing, the brightest samples were found based on wool fibers. Depending on the type of mordant, the following colors were obtained: Cu2+ cation made it possible to obtain green-brown shades, Al3+, Zn2+, Ni2+ cations gave colors in the yellow-brown shades; Fe3+ cation gave colors in black and brown shades. In general, the color fastness to wet and dry crocking for textile materials after dyeing with strawberry sepals extract are maximum for all specimens pre-treated with ferric cations except cotton and linen materials. The stability of color to perspiration in cotton, linen, viscose and wool samples ranges from 4 to 5 points. Color fastness to washing for samples from cellulose fibers are preferably 4-5 points, and for woolen is 4 points. The scientific novelty of the work is to determine the basic regularities of the dyeing process after pre-treatment with salts of metals Cu2+, Zn2+, Ni2+, Fe3+, Al3+ using as a dye of the strawberries sepals extract, which is a waste of the food industry.

The purpose of this work is to establish regularities of the leaching process and to determine parameters for leaching ammonium perchlorate from polymer crumb as solid propellant disposal products. The process of leaching ammonium perchlorate from the polymer matrix was carried out in a flask equipped with an agitator in a polymer matrix: water ratio of 1: 2, with such changing parameters as: temperature (20-80 °С), time of extraction process (1-4 h). Then, the obtained refined polymer matrix was filtered off, dried at room temperature, and weighed. The content of the chemical composition of the polymer matrix was determined in refined polymer matrix. The obtained polymer matrix was dried at temperatures of 70 ºС, 90 ºС, 100 ºС to constant weight, with intermittent weighing of dried samples. It was determined that the degree of leaching of ammonium perchlorate from polymer matrix when the leaching time is 2-4 hours is maximum, both during the process at a temperature of 20 °C and at a temperature of 60 °C and 80 °C, respectively. It was found that the maximum degree of ammonium perchlorate leaching from polymer matrix was 82.3% in the experiment with the following modes - the process temperature was 80 °C, the speed of the mechanical stirrer was 400 rpm, and the leaching process took 4 hours. It was found that the most preferable temperature range for the drying of refined polymer matrix is 90 to 100 °С. It was determined that the refined polymer matrix is a substance which is not particularly dangerous for transportation and can be recommended for use as a filler in compositions of emulsion explosives, or for extraction of nitramine.

Investigation of the influence of textile materials structure of different raw materials for hospital bedding on the ability to provide sensory comfort and durability. Theoretical and experimental investigations are based on the main positions of textile materials science. Sensory comfort and durability of textile fabrics were evaluated by thermal and mechanical properties. The measurement of thermophysical characteristics was carried out on the ALAMBETAinstrument, the abrasion resistance was determined on a Pilltester type 14. The strength of textile materials, the tangential resistance, the flexural rigidity and the resistance of dyeing to dry friction were determined by standardized methods. A comparative analysis of the sensory comfort of traditional textile materials for hospital bedding and fabric with bamboo fibers was carried out, which is determined by the mechanospecific sensations of skin receptors on the surface texture of the material, its roughness, stiffness, the feeling of cold or warmness when touching.Their thermophysical properties are determined, the evaluation of the feeling of cold or heat when touched is made according to the indicator "thermal absorption coefficient". By the method of an inclined plane the differences of the texture of dry and moisten studied fabrics was analyzed. The results of the wear resistance indicated that all fabric samples have high abrasion resistance; on part of the test specimens after 1200 cycles appearednap, on mixed fabric – piles.The values of strength and bending stiffness were determined and the effect of 5 washing cycles on these indices was determined. The resistance of the dye to the action of dry friction of all investigated materials is 5 points. The comparative analysis of the values of the coefficients of thermal absorption made it possible to evaluate the feeling of cold or heat when touched, which coincide with the results of the provided organoleptic determinations.It has been experimentally proven that the assortment of cotton and mixed textile fabrics used now for bedding can be supplemented with bamboo fiber materials that provide a high level of sensory comfort and durability. A new range of textile materials for bed linen has been proposed, taking into account the requirements of sensory comfort and durability.
