摘要
A method of tanning wherein an aqueous medium containing hide stock is unhaired, bated and acidified, and a chrome tan is charged to the acidified medium to effect tanning of the hide stock comprising providing in the acidified aqueous medium prior to or simultaneously with addition of the chrome tan, a water soluble or water solubilizable amino compound which has substantially no tanning properties of its own but which enhances the tanning afforded by a chrome tan in an amount effective to permit reduction in the chrome tan charge while obtaining an equivalent level of tanning.
