![]() It is indisputable that a split leather does not have the same quality features as a top-grain leather. Since the fiber structure of split leather is not as dense, they are looser and pull out further when torn. Cracks in split leather are usually visually noticeable due to the strong fibrous nature of the crack. Some allow it to be called leather, but only when further details make it clear that it's a split leather.Ĭoated split leather does not have the tear resistance of grain leather. Some countries don`t allow to label split leather as " leather". But the rules are different in almost every country. This makes it clear that the term "split" always refers to the less stable lower layer of the hide.Īs the quality of a split leather is lower than the top grain leather, there are rules about the use of the terms. In order to make the leathers more intelligible to the layman, this is an important separation of the choice of words in tanneries and in public. The drop split with the two rough sides is then no longer referred to as a "flesh split", but only as "split leather", "split" or " suede". The term "split" no longer appears in connection with the grain side. The leather dealer then uses terms such as " smooth leather", " aniline leather", " napa", depending on the leather type. The grain split is referred to as smooth leather when tanned.Īfter leaving the tannery, the term " grain split" is no longer used. The fibre structure is substantially denser in the upper layer of the grain side and is thus tear-resistant. The grain split is considered more valuable. Outside the tannery, only the flesh split is recognised as "split leather" ![]() Above is the grain split and below the flesh split. Leather that is too thick has to be shaved thinner again and the leather substance of the counterparts is lost when splitting and there is more work and waste in the shaving process. Thus, the technician at the splitting machine has to take many factors into account in order not to produce leather that is too thin, but also not too thick leather. Vegetable tanning agents fill the leather more, which results in a thicker leather. The tanning method also influences the thickness at which leather must be split. The tanner has to consider this difference in thickness when adjusting the splitting machine so that the desired leather thickness is achieved once the leather is dry. This water content also makes the leather thicker. The water content of a wet skin is three times heavier than the dry weight of leather. When adjusting the splitting machine, the tanner must take into account that the thickness of the skin is higher at this stage due to the water content of the wet skin. The drop-split leather is rough on both sides like the back of a leather. The split, separated from the grain split, is also called drop split. Sometimes, the leather is thick enough for a middle split. ![]() The obtained layers are designated as grain split or top-grain split and flesh split. Thicker leather, mostly cow leather, which is 5 to 10 millimetres thick, is split. ![]() If a skin is divided into several layers over the entire surface, this process is called "splitting". 6 Coated split leather - Laminated split leather.2 Video about the coating of split leather. ![]()
