Curtición de Pieles de Argyrosomus regiu(Corvina), con la Utilización de Diferentes Niveles de Curtiente Mineral.

Abstract

In the Pelt Processing Lab of the Faculty of Cattle Sciences, ESPOCH, the evaluation of both the physical and sensorial characteristics of the tanned argyrosomusregiu (corvina) pelt with different levels (7, 8 and 9%) of aluminium tanning was carried out. The experimental results were patterned under a completely-at random-Desing with a bifactorial arrangement, and it is due to this that the results indicate that in the evaluation of the physical resistances were registered the highest values for the stretching percentage (43.06%) and flexometry (83.88 N/cm2) when applying 8% of sulphur tanning while the best lastometry is obtained with the tanning with 7% of mineral tanning (4.52mm). The sensorial evaluation identified the highest answers for softening (4.56 points) and touching (4,38 points) in the tanned pelts with the 8% of sulphur mineral tanning; while the best filling was registered in the tanned pelts with the 9%. The effect both of the tryings and the interaction when not reporting statistical differences both for the sensorial evaluation and the physical resistances reflects the quality of the raw material that was standardized. The relation benefit-cost infers the highest nominal value in using the 8% of sulphur mineral tanning and that was of 1,27. Because of that it is recommended to tan with the 8% of mineral tanning since a strong, great-visual-beauty material will be able to be sent to the market.
