Cow leather
What is cow leather?
In the world, there are approximately 1.6 billion cattle including calves, buffaloes and zebus (as of 2011). 15 to 25% of these are slaughtered annually. Cow leather is the most widely used leather with about 65 to 70% of world production. Cow leather is used for soles and uppers of shoes, for car seats and furniture upholstery, belts and straps, saddles, leather clothing and much more. There is hardly any area, in which bovine leathers or calfskins are not processed.
In Brazil, there are 206 million cattle, which is the world's largest stock of cattle. That is 14.2% of the world's amount (as of 2013).
In Italy, which is by far the largest leather manufacturer in Europe, almost 100 million square meters of cow leather were produced in 2011. In Germany, the third largest beef leather producer in Europe after Spain, only 8.5 million square meters were produced.
Since beef is consumed world-wide, sufficient raw skins are also available for leather production and the price is therefore affordable.
Bovine leather is stable and firm and therefore versatile. The hides are large enough to be used for large areas. The surface of a cattle leather skin is about five square meters. For a large sofa, roughly 25 square meters of leather is needed. Depending on the size of the individual surfaces, the waste is between 30% and 45% and can be even higher for particularly large individual surfaces. However, there are differences between cattle breeds. A Bavarian cow usually yields twice as much skin area as a zebu. Although, there are zebu skins sold by a company called Mastrotto from Brazil with 5.5 square meters.
Cow leather refers to various types of leather from cattle, such as bull hide or cowhide. Minor differences between species relate mainly to grain pattern and haptic.
The typical density of a bovine leather skin is between 0.4 and 0.9 g / cm 3.
The tensile strength of cow leather is between 8 - 25 N / mm².
Normally, only the surface skin of cattle is processed to leather. There are rare exceptions, such as the bull testicles or the rumen leather.
Depending on the age (calfskin), sex (the car industry processes mostly bull leather) and weight (affects the size of the skin), rawhide dealers stores the skins after the slaughterhouse and sells them to the tanneries.
