| abstract | 1. METHOD FOR TREATING LEATHER, which includes pickling a mole in the presence of an additive that activates tanning, and subsequent chrome tanning in the presence of an alkaline reagent, characterized in that, in order to improve the quality of leather, reduce the consumption of tanning agents and pollute sewage during tanning, As an alkaline reagent, a mixture of sodium silicate and calcium dihydroxide is used at a consumption of 0.2-0.4%, respectively (based on silica) and 0.2-0.5% by weight of a mole, and an additive that activates tanning is introduced in the amount of 0.2-0.4% by weight of the mole. 2. A method according to claim 1, characterized in that phthalic acid or sodium polyphosphate is used as an additive in activating tanning. 3. The method according to claim 1, characterized in that chrome tanning is carried out with a tanning rate of 1.4-1.8% with a basicity of 33-40%. , |
