Aplicación de una Curtición Ecológica, Utilizando Diferentes Niveles de Granofin F 90, para Cuero de Calzado.

Abstract

In the Fur Tannery laboratory facilities of the Faculty of Animal Science of the ESPOCH, an ecological assessment using different levels of tanning Granofin F 90, for leather footwear, 36 goatskins spread over 3 treatments were performed, with 6 replicates each one and it two trials. The experimental results were modeled under a completely randomized design in accordance bifactorial. We determined that with 6% of Granofin F 90, the most efficient results flower breaking (11,34 mm), and tensile strength (34.93 N/cm2 ), was reported, greatly surpassing the requirements of the quality of leather. In the sensory appreciation we recorded the highest grades of the softness (4,58 points), and fullness (4,58 points), applying 6% of ecological tanning. When we observe the effect of treatments replicas similar results were determined to be an essential feature in the practical to produce various leather items field, so it is asserted that has been made to standardize the formulation of tanning goatskins. The higher cost benefit was obtained when we working with 6% of tanning Granofin F 90 (1,40); that is to say, a gain of 40 cents for every dollar invested, that will be compared with other industrial activities is profitable. So is recommended to use higher levels of Granofin F 90, to get leather with better physical resistance, sensory skills and greater economic benefits.
