Curtición ecológica de pieles de cabra con productos naturales para cueros de calzado.

Abstract

This bibliographic review project analyzed the ecological tanning of goatskins using natural products for leather to be used in the manufacturing of footwear. A compilation of information through available tangible and intangible resources was carried out. When analyzing the physical tensile strengths, the best results were recorded in the leather tanned with 7% Tare plus 4% Granofin F 90 (3140.69 N / cm2), while the elongation percentage (80.63%) and lastometry (11.78mm) achieved the highest responses when using mixed tanning with different levels of mimosa extract. In the sensory analysis, the best softness (4.75 points) and roundness (4.75 points) scores were obtained in the leather tanned with Tara, while the fullness (4.75 points), on the contrary, reached its higher weighting using hybrid tannins. In the benefit analysis (1.20), it was possible to determine the highest profitability when tanning the hides with 7% tare plus Granofin F 90, since the benefit / cost ratio was 1.28 that is, for every dollar invested it is expected to obtain 28% utility is quite attractive, so it is recommended to apply vegetable tanning since it is a product that, in addition to having a low commercial cost and producing good quality leather, has the advantage of being environmentally friendly, due to which is a technology that adequately replaces the universal tanning agent such as chromium, which can prolong its polluting effect even after the end of its useful life and is disposed of in inappropriate places.
