Evaluación de un sistema ecológico en el proceso de desencalado en la obtención de cueros pura anilina para calzado

Abstract

In the Lab of Tanning of Skins from the Faculty of Animal Sciences of the ESPOCH, it was evaluated an ecologic system in the process of delimed in the obtaining of pure aniline leathers with 3 treatments, 6 repetitions, in two consecutive essays giving a total of 36 experimental units, modeled under a Random Fully Design, with bifactorial arrangement. The outcomes infer that the application of 1.5% deliming product (T2) improve the flexometry (181.58N / cm): and lastometry (17.90 mm). The sensory appreciation reported the best qualifications with the application of higher levels of deliming product in another words 2%; since the fullness was of 4,67 points; roundness of 4.67 points; spring effect 4.42 points and grain loosening of 4.58 points above 5 points of reference and those correspond to an appreciation of excellent. In the development of the essays was not established statistical differences amongst Medias, that result positive since is an indicator that is reached to normalize the productive processes. The biggest profitability was reported in the leathers of treatment T3 (2%), as the benefit-cost was of 1.21; or it is the same to say that per each dollar invested is expected a profitability or gain of 21 cents of dollar. That is why is recommended to apply 2% of delimed product Dekalon CL-BR p, inasmuch as reports the best sensory qualifications and the biggest benefit-cost, which are very important aspects to consider by part of the artisans and users.
