Curtición de pieles caprinas utilizando diferentes niveles de mimosa en combinación con 5 % de curtiente sintético

Abstract

In the leather tanning laboratory of the FCP-ESPOCH, 24 goat skins were used the same ones that were treated from the tanning process with different levels of mimosa tanning (8, 9 and 10%), plus 5% of mimosa tanning in each treatment, the experimental units were modeled under a simple Full Random Design. The results show that the adequate level of mimosa tanning is 10% (T3), since the quality of the leather is improved allowing its positioning in very demanding markets, especially when labeling it with green seal both for the raw material used that is not the Traditional as the tanning products that has vegetal nature. The use of 10% mimosa produces leathers with greater tensile strength (1378, 14 N/cm2), lastometría (11.78mm) and percentage elongation (65.78 %), meeting the quality requirements of the Regulatory Agencies. The sensorial behavior of the tanned goats with 10% of mimosa tanning was excellent, since the weights of fullness (4.75 points) and flower fineness (4.63 points) were the highest and allowed to predict their greater acceptance. The highest profitability is achieved by applying higher levels of mimosa tanning with a cost benefit ratio of 1.32, which means that for every dollar invested, it is expected to receive 32 cents of the dollar, which is very interesting especially in the current moments of our country that there is an economic instability and investment is low therefore the sources of labor are scarce.
