“…The generalized desirability criterion is a weighted product of partial desirability criteria, which, in their turn, are normalized estimates of the state of the studied system, presented in fractions of a scale unit (from 0.0 to 1.0) and obtained from target functions by encoding these functions based on a special "scale of preferences". Harrington's desirability function was used in this study, which showed sufficient efficiency compared to other desirability functions [25]. The effectiveness of the desirability-based approach compared to other multi-purpose optimization strategies has been confirmed by numerous studies [26][27][28][29].…”

The paper features the rawhide collagen defibrillization process in the elastic leather materials manufacturing. Optimal colloid-chemical properties of semi-processed products were defined by way of using mathematical optimization of rowhide liming process. It was found that during the alkaline treatment of raw material (in the operating temperature range) the degree of defibrillation of raw material raises (in proportion to the derm collagen swelling) with increase in the ratio of process solution to the mass of raw material, and the extremum of hydrothermal stability and leather yield can be estimated. It was also shown that the degree of swelling decreases with a decreasing ratio of sodium sulphide and sodium hydrosulphide, and the leather area yield reaches the maximum value at the equal proportion of these reagents. Multicriteria optimization of rawhide liming process using the Harrington’s desirability function was carried out. The developed technology of soaking and liming was tested under production conditions. The above-mentioned low-waste technology provides elastic leather materials with a yield increase by 3.5%, which meet the industry standards requirements.

“…The use of raw materials of nutria skin for velour resistant to the environment requires a significant modification of the porous structure of the skin tissue [1]. For this purpose it is necessary to carry out the processes of filling-hydrophobization of fur semi-finished products using the methods of mathematical modeling and multifactor optimization.…”

The formation of hydrophobized nutria fur velour has been carried out using the optimized alkenmalein acrylsyntane composition. Based on the implementation of the synthesized experimental plan “composition-properties of velour” by the modified McLean-Anderson method, the optimization of filling and hydrophobizing composition has been performed by Harrington method. The optimized composition involves the use of, wt. %: alkenmalein polymer – 54.1, polyacrylic emulsion Melio Resin A-821 – 18.8, reagent based on 2-naphtholesulfonic acid and dioxins-phenylsulfone – 27.1. The developed technology of forming hydrophobized nutria velour has been tested at the experimental production of leather enterprise (Chinbar Private Joint Stock Company, Kyiv, Ukraine). Nutria fur velour obtained by the developed technology is characterized by a significant increase in water resistance in dynamic conditions. The advantage of this technology is the production of fur velour with a higher yield of 5.4–5.6 % compared to the semi-finished chromium-aluminum tanning. The optimized filling and hydrophobizing composition can be effectively used in the technologies of manufacturing sheepskin and leather materials with high water resistance. According to the complex of properties, the obtained hydrophobized nutria velour is suitable for the production of uncovered items of various purposes, which will be used in extreme conditions.
