DETERMINATION OF RATIONAL PARAMETERS OF LIQUID FINISHING OF LEATHER SEMIFINISHED PRODUCT USING ACRYLIC POLYMER AND MODIFIED FATS

A mathematical model of the processes of liquid finishing of semi-finished leather products using modern chemical materials in the form of acrylic polymer and modified fats has been obtained, revealing the influence of the consumption of these materials on the content of substances extracted by organic solvents (the so-called unbound fat), elongation at a stress of 10 MPa and the yield of leather by area. Rational parameters of liquid finishing have been determined, allowing for more efficient use of scarce raw materials while reducing the harmful burden on the environment.
