Изобретение относится к способам химической обработки голья и может быть использовано в кожевенной промышленности, преимущественно при производстве кож для низа обуви. В способе выработки кож, включающем пикелевание голья, хромирование и циркониевое дубление, пикелевание проводят при расходе серной кислоты 1,5 - 1,7% (100%-ной) от массы голья в присутствии 1 - 8% алюмокалиевых квасцов, а циркониевое дубление осуществляют основным сульфатом циркония формулы Zr(OH)y(SO4)x • n Н2О, где x = 0,6 - 0,8, y = 4 - 2x, n = 1 - 10, одновременно с хромированием.The invention relates to methods of chemical treatment of the hide and can be used in the leather industry, mainly in the production of leather for bottom shoes. In the process of making leather, including pickling the hide, chrome plating and zirconium tanning, pickling is carried out at a consumption of sulfuric acid of 1.5-1.7% (100%) by weight of the hide in the presence of 1-8% potassium alum, and zirconium tanning is carried out basic zirconium sulfate of the formula Zr (OH) y (SO 4 ) x • n H 2 O, where x = 0.6 - 0.8, y = 4 - 2x, n = 1 - 10, simultaneously with chrome plating.
