Obtención de Cuero Wet con la Utilización de Diferentes Niveles de Sulfato con la Utilización de Diferentes Niveles de Sulfato de Aluminio para la Elaboración de Calzado Ortopédico.

Abstract

In the installations of Skin Tannery Laboratory of the FCP (Cattle Sciences Faculty), at the ESPOCH, the utilization of three different levels of mineral tannery Tanal W (7, 8 y 9%) was evaluated in the obtaining of Wet White Skin with 5 repetitions in 2 consecutive essays, under a completely at random design in combinatorial arrangement, giving a total of 30 experimental units. The results reported that in the production of Wet White Skin, the utilization of 9% of Tanal W increases the physical resistances to tearing (65,30 cycles); to tension (162N/cm ) and percentage of elongation (81,10%); values that are superior when comparing with the quality requirements of the skin for orthopedic footwear. The sensorial appreciation determined the best scores when using 9% of Tanal W, this is fullness (4,70 points) and roundness (4,70 points), with condition of excellent; while the best score for softness was reported in the skins with 7% of Tanal W. When replying the production of Wet white skin, statistical differences weren't reported among the medias as well as for the physical variables as for the sensorial ones. The economical profitability which is product of the accountable exercise points out the best results when using bigger levels of mineral tanning (9%), since it infers a profit-cost of 1,27. So it is recommended to tan goat skins with high levels of Tanal W(9%) since the physical resistances are elevated and the sensorial scores are improved.
