Evaluación de un acabado catiónico con diferentes niveles de cera en la obtención de cuero pulible de cabra

Abstract

In the leather tanning laboratory of the FCP, the evaluation of a cationic finish with different levels of wax in the production of goat leather was carried out, 3 treatments were used, 8 repetitions giving a total of 24 experimental units, modeled under a Completely Random Design, simple. The results indicate that the most suitable level of cationic wax in the dry finish was 100 g, of cationic wax; since it was obtained, a very natural and high quality polished leather. When evaluating the physical resistances of the leather was determined; the highest tensile strength (2182.30 N / cm2) and dry rub (125.00 cycles), when using 80 g of cationic wax, the highest percentage of elongation (54.69%), was reached in the leathers to which 100 g of wax was applied, in leathers for the manufacture of footwear. The sensory evaluation established the highest touch and softness scores in the leathers of the T2 treatment (100 g); meanwhile, the best filling was achieved in the leathers of the T3 treatment (120 g), since the leathers provided a better sensation when handled and above all an ideal fall for the manufacture of footwear. Once the production costs of the polishing leather were determined, the greatest cost benefit was observed in the leathers of the T1 treatment, with a value of 1.23; that is, a profit of 23 cents for every dollar invested.
