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 10-100, temperature of 20-50 degree C and duration of 5-25 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 10-90, temperature of 10-30 degree C and duration of 2-10 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 degree C and duration of 6 min. Conclusion. Rational mode to extract hydrophilic extractives hydrological of the wool is hydraulic kit 60, temperature of 42 degree C and duration of 6 min.otherwoolвовнаsoakingзамочуванняextractivesекстрактrankingранжуваннякафедра технології жирів, хімічних технологій харчових добавок та косметичних засобівArticle
