Method of producing a split leather, especially for automotive applications subject to temperature and humidity fluctuations

摘要

Between a chrome tanning step and a fat liquor treatment step, a flesh side split leather is subjected to shaving on both its split and flesh sides to a thickness of 1.1 to 2.5 mm, preferably 1.2 to 1.5 mm and is then aftertanned. After a split side dressing of the dried butt, a further shaving operation is effected on the flesh side to a thickness of 0.5 to 1.0 mm, preferably 0.7 to 0.9 mm, whereupon the flesh side is also dressed. The result is a split leather which is particularly effective for use on automotive vehicle dashboards and has low shrinkage even when subjected to high temperature and moisture fluctuations.
