Abstract: The influence of the chemical composition of the alkene-maleic composition on the water resistance, hygienic and physico-mechanical properties of the hydrophobized chrome tanned leather obtained from the leather of open cow is studied. It is established that hydrophobization of the leather semi-finished product with an alkene-maleic composition significantly increases the water resistance of the obtained leathers compared to unmodified ones, which results in an increase in the water-bathing time in dynamic conditions 35-47 times depending on the thickness and stability of the elastic-plastic properties of the leather during cyclic watering-drying. It is shown that with an increase in the thickness of hydrophobized leather from 1.8 to 2.4 mm, the water vapor permeability and air permeability decrease, respectively, by 1.2-1.6 and 1.5-1.7 times, at the same time, their hygroscopy increases by 10%. The complex physico-mechanical and hygienic properties of the leather, formed by the developed technology of hydrophobization of the chrome semi-finished product using alkene-maleic composition, meet the requirements of DSTU 2726-94 Leather for shoes and DSTU 3115-95 Leather for garments. As a result of the research, a technology for hydrophobization of semi-finished chrome tanned leather can be implemented in industrial production for the manufacture of water-repellent leather for special purposes.
