Pig leather or Lamb leather are much thinner than Cow leather. Cow leather is so thick that it is usually split into two usable parts. An un-split cattle skin has a thickness of about 45 millimetres. Leather in such a thickness can hardly be stitched. Therefore, these type of thick leathers are not found in the car sector at all and very rarely in the furniture sector.
To achieve the desired leather thickness, leather is first split and then shaved.
Cow leather is usually split into at least two layers.
The usual thickness for car or furniture leather is 0.9 to 1.2 millimetres. Leather that is thicker than 1.4 millimetres is called thick leather. Garment leather of light leisure jackets has a thickness of 0.5 to 0.9 millimetres. The leather thickness varies depending on the type of leather
Since leather is a soft material, it is difficult to measure the thickness simply with a calliper. The soft material would be pressed thinner and the results would be different depending on pressure. In the case of standardized leather thickness measuring devices, the thickness of the leather is determined with a predefined area and a predetermined contact pressure. As leather is not uniform in character or content, it is nearly impossible to measure uniform results over the entire surface of a skin. The measurement of the thickness of leather is regulated in national and international standards.
Special measuring device to determine the leather thickness.
Close up view of the scale of the measuring device. The hide of leather in this case was 1.7 millimetres thick.
During the shaving process in the tannery, the leather thickness is measured repeatedly.
In case of vegetable-tanned leather, the following leather articles are produced according to leather thickness:
1.0 to 2.5 mm: wallets, leather bags, book covers
2.0 - 2.5 mm: robust Leather bags, leather straps
2.8 - 3.5 mm: belts, soles of shoes, knife sheaths
Heavy duty belt: USA belt with 6.3 mm leather thickness. - Thin, butter-soft lamb leather.
Video about split leather and coated split leather
Video about the production of laminated split leather.
