Abstract

In order to find out the locational differences of different types of sole leathers, studies were made on samples obtained from various parts of tanned hides. For this study, the most commonly used chrome and vegetable tannages were used and the leathers were tested both in the crust and in the finished state for various physical properties. Tensile strength, elongation at break, apparent density, real density, air space, water absorption, water penetration, moisture absorption, water vapour permeability, air permeability, compressibility, resiliency, abrasion resistance and flexibility were determined on samples taken from eight different locations. The effects of tanning were assessed by determining the same physical properties on acetone dehydrated limed and delimed samples obtained from various parts of the hides.
