Producción de cuero ovino con acabado plena flor utilizando diferentes niveles de cera catiónica

Abstract

The objective of this research was to produce sheep leather with a full grain finish using different levels of cationic wax. It was developed in the Leather Tanning Laboratory of the Animal Science Faculty at ESPOCH. 24 adult sheep skins divided into 3 treatments were used with 8 repetitions. The statistical techniques were: Analysis of Variance (ADEVA), with probability of (P> 0.01), Kruskal Wallis Test for sensory variables, Separation of Means by Tukey, with probability of (P> 0.01) and Regression Analysis and Correlation for variables that represent significance. The results determined that by applying different levels of wax (120, 130 and 140 g / kg of paint) in the formulation of the cationic finish for sheep leathers with a full grain finish for casual footwear, a very good quality material is achieved. The highest responses were established when using 140 g of cationic wax since the tensile strength was 1579.69 N / cm2, the mean elongation was 83.04% and the resistance to dry rubbing was 4.75 mm. In addition, the touch (4.75 points), fullness (4.44 points) and softness (4.75 points) made the material very resistant, but at the same time with a very high sensory beauty. When analyzing both the physical resistance and the sensory qualifications of the leather, it was estimated that the best results were achieved with higher levels of cationic wax (140 g), which manage to exceed the requirements of the quality standards of regulatory bodies, as well as the judge's findings. The highest cost profitability was achieved by using 140 g of cationic wax in the finishing formula, since the value was 1.22, that is, for every dollar invested there is a profit of 22 cents.
