Leather can be differently heavy. A thick leather is heavier than a thin leather. A stronger oiled leather is heavier than a dry leather. A compressed leather is heavier than a very soft leather with loose fibers and many air pockets in the fiber structure.
For leathers in transport means (vehicles, airplanes), each saved gram means a lower energy consumption. With 400 grams of weight per square meter of leather, extra light weight leather was developed for this purpose. Also in case of leather clothing, a lighter weight is more comfortable to wear, especially in thick and warm winter coats or motorcycle leather suits.
However, in case of reduction in leather weight, the previous stability and quality properties and in particular the reduced flammability and fire retardancy of leather must be retained.
The weight reduction also has advantages for the tanneries. In the production process, less waste water is produced and less chemistry is used for the tanning process.
Since leather varies in weight according to humidity, a leather must be measured at controlled air humidity in order to obtain comprehensible comparison values.
Each gram saved saves kerosene.
