Implementación de un prototipo de automatizado Airless MIx para nel acabado en seco de cueros

Abstract

At the laboratory facilities of tanning skins CIIP (Engineering career in Cattle Industries), of the FCP (Faculty of Cattle Science) from the ESPOCH, was carried out leather tanning, Construction and installation of the prototype Airless Mix for pigmenting the leathers, as well as physical and sensory analysis. A sampling of 10 tanned leather was performed to the vegetable and chrome and the results were tabulated with a descriptive statistics. By implementing the prototype Airless Mix, for finishing leathers dry, taking into account the established guidelines set out in National and International regulations concerning paints, lacquers and materials, automated the process of finishing, especially for special leathers. The equipment with the elements and materials that ensure a life time minimum 5 years with proper maintenance program established in a manual operation. The evaluation of the physical resistance of pigmented leather, it showed that when using chrome goatskins the results were more efficient as they comply fully with the quality standards specifically of flexibility (76000 flexions ), moist rub resistance (120 cycles) and dry (220 cycles). Sensory evaluation found that the pigmented leathers chrome excellent scores were achieved with averages covering power and feel of 4,60 points; that is very soft leathers and well impregnated paint. The production costs of equipment were US $ 2005,75, economically more profitable that other similar use but more expensive
