Utilización de una conbinación de tres curtientes, en el adobe de pieles de cabra para calzado

Abstract

In the fur tannery of the FCP of the ESPOCH, it was evaluated the usage of a combination of three tanneries in the goat fur dressing for footwear. The experimental units (24 furs) were distributed by a completed, simple and random design. The treatment T2 (7% of tare plus 7% of aluminum sulphate and 2% of glutaraldehyde) was identified as a suitable combination of tanneries. Since it improved its classification, therefore it can be replicated in the factory. The greatest physical resistance of the goat fur was established when using this treatment. Since this reach the European standards of the leather for shoes specifically. Resistance to the tension (2357, 62 N/cm2), dry front (177, 88 cycles), this means that the leather supports multidirectional tensions carried on intermingling fibrillar. The sensorial evaluation the best scores when using a tanning with a combination of 7% of the tare plus 7% of the aluminum sulphate and 2% of glutaraldehyde (T2), weightings of fullness (4,63 points), softness (4,75 points), rounded (4,88 points). These scores belong to the excellent scale. The highest rate of benefit cost was for the T2 with $ 1.25. In other words, per each dollar invested, it is expected to earn 25 cents. In addition it is economically profitable and it is a great ecological alternative to replace the chrome by another king of tanning which is eco-friendly.
