Method for producing reptile leather or leather product using hexavalent chromium treatment agent, and reptile leather or leather product using hexavalent chromium treatment agent |
| abstract |
Provided is a method for producing a reptile leather, in which a leather can be treated with a hexavalent chromium treatment agent in the course of leather production without change in the visual appearance of the leather. The method for producing a reptile leather according to the present invention comprises: a chrome tanning step of performing chrome tanning on reptile skin to obtain a leather; a dyeing-fatliquoring step of performing dyeing and fatliquoring simultaneously on the leather subjected to the chrome tanning; and a finishing step of performing finishing on the leather subjected to the dyeing and fatliquoring, the method further comprising a hexavalent chromium treatment step of, prior to the finishing step, applying a hexavalent chromium-reducing compound capable of reducing hexavalent chromium into trivalent chromium to the leather subjected to the chrome tanning in the chrome tanning step. |
