OF FUNCTIONAL AND TECHNOLOGICAL PROPERTIES OF SEMI-FINISHED LEATHER PROPERTIES WITH DIMETHYL SULFOXIDE USE

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