Utilización de productos craquelados en la elaboración de cuero maseratti de pieles ovina de baja selección

Abstract

The application of different levels complexing product in the skin tanning bath of goat skins was evaluated in the tanning workshop of CFP, of ESPOCH, so that the experimental units (24 hides), were distributed under a Completely Random Simple Design, with tree treatments and eight replicates. The evaluation of the physical resistance determined the best tensile strength using 1.50% complexing product, the highest elongation percentage with 1.75% and finally the best lastometry when applying 2%, with results of 9.61 mm, however comply with the internatinal regulations IUP (International Union Physical Test) 6 and 8 (2002) of the spanish Association in the Leather industry. It is seen that the best results are achieved by using 2% of complexing product as the highest marks of fullness (4.75 points), softness (4.88 points), and roundness (4.3 points), with excelleent weights in each of them. The highest cost-benefit ratio was achieved in the treatment lot T3 (2% of complexing product), with a nominal value of 1.34; That is to say that for every dollar invested a profitability of 34% is expected and that is interesting especially taking into consideration the present unstable situation of our country in which most of the companies have emigrated to other countries
