Influence of Different Waterproofing Agents on Leather Water Vapour Absorption and Permeability

In this article, the influence on finished leather properties of five different waterproofing agents has been exemined. Wet-salted bovine hide (weight category 35 kg) was treated in a half-industrial environment by conventionaly used liming, tanning and retanning processes. 9% offers of five different waterproofing agents were used for the waterproofing process. The levels of water vapor, fats, ash and Cr2O3 were determined for the crust leather. The water vapour permeability, leather porosity to water vapour and absorption of water (measured on both the Kubelka apparatus and the Bally penetrometer) were determined. The water repellency properties of each waterproofing agent were estimated from results.
