Abstract
590,834. Treatment of leather. HODGSON & SONS, Ltd., R., and CHESHIRE, A. Jan. 13, 1945, No. 1072. [Class 76] Vegetable-tanned leather is rendered less liable to ageing by providing therein after tanning an oxalate of an alkaline earth metal (including magnesium), a water-soluble oxalic acid ester, or oxamide. The leather may first be treated with oxalic acid to convert any iron present into an oxalate complex. By treatment with solution of oxalic, acid or a soluble oxalate, and then with a solution of an alkaline earth salt, the insoluble oxalate is formed in situ. In an example cow hide after deliming is washed with oxalic acid at pH 2.5, adjusted to pH 4.0 with borax, and tanned with mimosa extract in the presence of oxalic acid. The leather is soaked in oxalic acid solution and then in calcium acetate solution. In another example solid potassium oxalate and calcium acetate are drummed into wet leather.
