| Résumé : |
In this part of the paper we try to define the influence of leather compactness in four topographic areas tested in an electron scanning microscope, namely, neck, croupon, butt and belly, on a behaviour of pigskin leather under wear conditions. Fatigue tests in the range 0-20 % extensions and apparent density tests were performed. Total compactness of the structure was defined for tested topographic areas by means of loosening ability. It was found that the butt, commonly considered to be the most compact region of pigskin, shows the highest ability to loosening (apart from belly parts) under wear conditions. Lesser ability to loosening shows neck area and the least, croupon area. The results of apparent density tests confirmed the compactness of structure defined by fatigue tests in several topographic locations. |
