Elaboración de Cuero Plena Flor para Calzado con la Utilización de Diferentes Niveles Glutaraldehído en la Precurtición.

Abstract

In the laboratory Fur Tannery, Faculty of Animal Science of ESPOCH, we evaluated the performance of physical and sensory characteristics of goat leather for shoes tanning with glutaraldehyde different levels (2, 3 and 4%), in two trials and five repetitions under a completely randomized model under bifactorial. In applying the analysis of variance of the results of physical measurements of the leathers were highly significant differences between treatments ma presenting higher physical resistances in the leathers treated with the lowest level of glutaraldehyde (2%), reporting to the elongation percentage (86.1%) resistance to abrasion (59.60 cycles) and flexometría (167.60 N/cm2). Meanwhile, in the sensory evaluation at the discretion Kruskall Wallis presented the highest grades in the hides that were pretannage with glutaraldehyde ma high for the filling (4.70 points) and roundness (4.70 points), in contrast for ease of flower showed the best result in the pretannage leathers with 2% glutaraldehyde, whose score was 4.70 points. So in conclusion the best response was obtained by applying the tanning of goat skins 2% glutaraldehyde, since, were significantly elevated physical resistance full grain leather for use in the manufacture of footwear, which suffer from daily use multiple forces that can break the fibrillar structure.
