“…Designs of machines, based on the fiber-transporting principle, using the irrigation of a wool layer through nozzles under pressure, were first proposed in Australia [10]. Studies have shown that the process of wool washing by using the nozzles had such advantages as: it is continuous and is cheaper than the standard process; wool washed this way is better at wool combing; pH of the washed wool does not exceed 8, despite the use of alkali.…”

“…We presented earlier a solution to two auxiliary problems on the acoustic wave diffraction at gratings from the perfect rigid rods and a layer of wool. We obtained analytical expressions for the respective coefficients of reflection and passage (7)- (10). Using the method of scattering matrices [17] and the solution to these two auxiliary problems, we shall obtain coefficients of reflection and passage for a layer of wool, shielded by two periodic gratings from the perfectly rigid round rods.…”

“…The method of scouring the wool fiber with the aid of organic solvents does not have such side effects as the method mentioned above [4]. At the same time, there are the problems of toxicity and explosiveness of technology, high financial cost of purchasing the appropriate equipment and the need for constant presence of highly qualified personnel.…”

“…These impurities constitute half the weight of raw wool, which causes a non-white color in wool. 7 The impurities in wool fiber differ depending on factors such as the location, sheep breed, climate, and the environment in which the sheep are reared. Each kilogram of raw, contaminated wool contains approximately 150 g lanolin, 40 g suint, 150 g dirt, and 20 g vegetable matter, and yields only 640 g of wool fiber.…”

There is increasing concern regarding the existing sheep wool processing technology in the textile industry owing to the enormous volume of toxic effluents generated. The application of supercritical carbon dioxide (scCO2) in sheep wool processing is cleaner and increases wool fiber production while avoiding toxic effluent generation. scCO2 is a novel clean technology that can be utilized in sheep processing for sterilization, cleaning, and drying sheep wool at the same time. In the present study, scCO2 was used to treat sheep wool with varying pressure, temperature, and treatment time. These parameters influence the scCO2 treatment of sheep wool fiber through the inactivation of microorganisms and improvement of the whiteness index. The identification of bacteria in sheep wool was carried out based on biochemical analysis by molecular means, using 16s rRNA sequencing. It was found that scCO2 completely inactivated the microorganisms present in sheep wool and potentially enhanced the percentage whiteness index at the highest pressure of 30 MPa, temperature of 80°C, and treatment time of 80 min. Several analytical methods were employed to assess the physicochemical, thermal, and morphological properties of untreated and scCO2 treated sheep wool fibers. The results show that scCO2 effectively removes the impurities and completely inactivates the microorganisms present in sheep wool. The findings of the present study reveal that scCO2 can be utilized as an alternative treatment technology for sheep wool processing in the textile industry.
