Abstract: A process for the production of leather using one or more reaction products of (a) triamines or higher amines with (b) at least one compound of the general formula I A1-R1??I where R1 is selected from hydrocarbon radicals having 10 to 5000 carbon atoms, straight-chain or branched, saturated or having from one to three C—C double bonds, and A1 from groups capable of reacting with amines.

Abstract: A leather finishing process in which, in pertinent part, a warm water milling step is added after the base coat is applied to “crust” leather and cured. The warm water contains at least one dye fixation agent including but not limited to about 0.1-2.0% by weight of formic acid. Moreover, the base coat itself is an aqueous base coat containing at least two polymers such as an acrylic salt or a polyurethane salt. Between the polymeric constituents of the base coat, the acid fixation agent, and the use of the warm water milling step after the base coat has been applied and dried, a surprisingly natural feel to the leather is attained without loss of excellent adhesion, wear-resistance and other properties when the leather is completely finished.
Abstract: A process and apparatus for the treatment of hides and skins (3). The hide or skin is placed on a support (1, 2) and sealed to the support around the edges of the skin or hide. A treatment liquor is then supplied under pressure between the skin or hide and the support to distend and stretch the skin or hide to permit the more rapid penetration of the treatment liquor into the skin or hide.
