How to control leather strength
Strength properties have always been a topic of discussion, especially for thicker, firmer leathers as well as for soft and light nappa’s. A test to give oneself a first impression of its strength, is done by cutting a small distance from the edge and then tearing it by hand.
It is a simple and effective way of assessing the leather. Subsequent calibrated testing, more often than not, confirms one’s suspicions.
Many factors influence the leather’s strength properties. Insufficient strength properties are usually a result of a damaged fibre structure. It can occur in many stages of the process. The problem may be traced back to soaking or liming, splitting or shaving or even to retannage and fatliquoring.
