The actual problem of the primary wool processing is economical consuming of water and energy resources.Materials and methods. This article contains optimization of the parameters of wool soaking according to the planned experiment using Latin squares. It was determined the technological conditions of wet wool cleaning. Among the factors that affect wool cleaning while soaking, we've also investigated hydraulic kit (ratio water : dry wool), temperature, duration. As a response on changing factors we've chosen refractive index n, the pH of exhaust water.Results and discussion. In the first stage we've determined the impact of hydraulic kit in the range of 10100, temperature of 2050 C and duration of 525 minutes. To compare the effect of the studied factors we've normalized values of the factors' levels. Presented equations show that the smaller hydraulic kit soaking, the more extractives are in the water.In the second stage we've determined the impact of hydraulic kit in a range of 1090, temperature of 1030 C and duration of 210 minutes. With the increase in the ratio of water : wool the content of the reduced extractives in waste water is decreased. It was also found that there's a directly proportional linear describing dependence of content of extractives in waste water after soaking on temperature. The higher temperature, the more extractives are removed from the wool to the waste water.Factors have been ranked according to their influence on the process of wool soaking. The most influential factor that affects removal of extractives is hydraulic kit. Temperature is another influential factor. There are certain rational conditions for extraction of hydrophilic extractives of the wool such as hydraulic kit 60, temperature of 42 C and duration of 6 min.Conclusion. Rational mode to extract hydrophilic extractives hydrological of the wool is hydraulic kit 60, temperature of 42 C and duration of 6 min.
Introduction. Currently, synthetic detergents with a weakly alkaline pH are used for scouring wool. The combination of surfactant Sles 70 with an aprotic organic solvent with dimethylsulfoxide (DMSO) allows you to create a neutral detergent and needs to determine the rational modes of wool scouring. The purpose of our study was to find the rational parameters of scouring fine-wool hair. Materials and methods. In Latin squares, an experiment was conducted to determine the effect of the concentration of Sles 70 in the scouring solution in the range of 0.1 to 3.1 g/dm 3 , the concentration of DMSO 0.01 to 0.61 g/dm 3 , the hydromodule 10 to 100, the temperature of 30−48 С for cleaning fine-wool fibers while scouring the wool fiber with the specified combined detergent. Results and discussion. In the investigated range of variation of factors, the influence of the hydromodule on the purification of wool and the extraction of extractive substances from the surface of the fiber into the waste solution was most pronounced. Hydro module 40 and more allows you to clean the wool from grease and dirt. The temperature has a stable effect in the given range, so all the investigated values of temperature contribute to the removal of fatty contaminations of wool for this component of the detergent solution. Аccording to the hydromodule 70 and 100, as well as the concentration of 1% by weight Sles 70that is, for concentrations of surfactants above the critical concentration of micelles (CCM)the fibers of wool are also cleared during scouring. It is logical to note that the concentrations of surfactants below the CCM have reduced the effectiveness of wool cleaning. The concentration of DMSO also had a slight effect on the wool treatment compared to the hydromodule. Conclusions.The rational mode of single scouring of wool is the use of a hydromodule 40, a concentration of 1% by weight. Sles 70 and DMSO concentration to 0.61 g/dm 3 in the temperature range 30−48 С. The quality of the scouring can be improved by increasing the disposable water dispenser or by scouring it with a minimum of water.
Introduction. Washing of wool is carried out in an aqueous environment in order to remove contaminants and wool fat (zhyropit). Remove sewage from sewage. The purified fat of wool (food additive E913, lanolin) is widely used in the production of food, perfumery, cosmetics and specialty products and preparations. Materials and methods. Sles 70 was washed with wipes. To find rational wool washing parameters, the mathematical planning of the experiment was performed using Latin squares. Experimental data was processed using mathematical statistics in the Matcad package. Results and discussion. The influence of Sles 70 concentration in the washing solution in the range of 0.53.5 g/dm 3 , the hydromodule 1050, the temperature 2050 °С and the duration of washing 2 to 32 minutes were determined for extraction of extractives from sheep wool into a washing solution. The rational parameters of washing of fine-wool hair are revealed, influential factors are determined. The possibility of reducing the amount of water used during washing is studied. A regression equation is obtained that approximates the effect of normalized factors on the refractive index n (n D 20) of waste water. Three essential and significant factors on the amount of extracted substances extracted in the washed solution are selected. The most influential factor on the refractive index of the spent washing solution is the temperature. Further on the significance of the effect is the hydromodule, with the temperature and the hydraulic module exhibit a measurable effect on the refractive index. The less important factor is the duration of the washing process. The concentration of detergent Sles 70 was an ineffective factor in the process of washing the wool, since the detergent was sufficient to form a micelle in a clean solution. Conclusions. It is determined that within the limits of the investigated range, the rational mode is as follows: washing at a temperature of 40 °С and a hydromodule of process 10 (the ratio of aqueous solution: wool 10:1) for a duration of 10 minutes washing solution Sles 70 at a concentration of 1 g/dm 3 .
