Evaluación de la Aplicación de 3 Niveles de Parafina Sulfoclorada en la Elaboración de Cuero para Calzado

Abstract

In the leather tannery laboratory, Animal Science Faculty of the ESPOCH, were evaluated the application of three different levels of paraffin sulfoclorada in the preparation of leather for shoes. The number experimental units were 30 goat skins, modeled under a completely randomized design under two-ractor where the factor A, were paraffin levels and factor B, the replicas. Analysis of variance showed physical resistance highly significant differences (P <0.05) to be reported the best tensile strength (160.60 N/cm2), and percent elongation (81.6%) when working with 8% paraffin sulfoclorada, evaluation of sensory characteristics of fullness (4.80 points) and touch (4.70 points), recorded the highest grades, while working with 8% paraffin sulfoclorada. The proof effect on physical and sensory characteristics of goat leather reported no significant differences in each of the variables evaluated, regardless of the amount of wax applied to the grease sulfoclorada, there is a higher profit margin when using 8% paraffin, which reports ayield of 23% (B/C 1.23). It recommended that if the quality requirements of the producers of shoes are directed to a material with good tonnage good tension or elongation and excellent elastometry, work with 8% of paraffin in the lubrication of goat skins.
