Abstract
The evolution of derma porosity during pre-tanning, tanning, retanning, and modifications with inorganic particles was investigated with techniques of standard contact porosimetry, transmission, and scanning electron microscopy. The method, which allows us to perform quantitative analysis of pore size distribution of the hierarchical structure, has been proposed. The interrelation between porosity due to different elements of the structure (helices, microfibrils, fibrils, fibril bundles, and fibers) and the total porosity was found to be described by a linear polynomial function. Ordering-disordering, loosing-compaction, and shrinkage-swelling at each structure level, which are affected by chemical treatment of the derma, tanning, retanning, and filling with bentonite, are analyzed.
