- Annotation: The work is devoted to the study of the possibility of using dimethylsulfoxide (DMSO) in the technology of obtaining a semi-finished leather product to improve its functional and technological properties and to intensify the process of leather production. The semi-finished leather product was prepared according to the traditional (control) and experimental technologies by dipping method. The experimental technology involved the introduction of DMSO into ash, pickle and tannin solutions in various concentrations: 2.0; 2.5; 3.0 % of the weight of the minnow for each operation, as well as in the proportion of 3.0 % in the ash solution and 1.5% in the pickle and tannin. The best results on the welding temperature and deformation properties of the semi-finished leather product were obtained when using DMSO in concentrations of 2.0:2.0:2.0 % and 3.0:1.5:1.5 % of the minnow weight. In addition, the advantage of the proposed technical solution is the ability to optimise the process of ashing and pickling.
