Study of the effect of high-energy discrete processing on the extraction kinetics and properties of wool grease

Development of a two-step technology of scouring wool by the method of high-energy discrete treatment

“…Saponification number decreases by 4 % (from 134,64 to 129,03 mg KOH), which numerically is correlated with the indicator of amount of glycerin in grease. Taking into account our own accumulated experience and works by other scientists [24][25][26][27][28][29][30][31][32][33] on the application of HDP for intensification of different technological processes and the obtained data, we believe that HDP has a comprehensive influence during processing wool fiber in the course of washing and further extraction of wool grease.…”

“…Secondly, chemical transformations occur in water during HDP, as a result of which free radicals (4,2 mmole/liter under the influence of HDP for 2 minutes) and peroxide of hydrogen (0,1 mmole/liter under the influence of HDP for 2 minutes) are formed, which, in turn, influence both wool fiber and wool grease [33].…”

Examining a change in the properties of coarse wool fiber under the influence of electrical discharge treatment

“…Such processes include high-voltage electrical pulse discharge in a liquid, accompanied by the emergence of electric discharge non-linear bulk cavitation (EDNBC). Papers [12][13][14][15] proved a fundamental possibility of its use in various technological processes. In addition, EDNBC has a number of advantages to improve the rate of technological process and equipment performance, reduce its power and material consumption compared with other types of cavitation.…”

“…In the course of the study [12][13][14], the process of electric discharge treatment of wool was examined and its basic technological parameters were determined. According to results of the experiments, it was found that due to characteristics of histological structure of wool fibre, EDNBC affects the wool of different fineness in various degrees.…”
