Curtición de pieles caprinas (Capra hircus), con diferentes niveles de oxazolidina, en combinación con castaño.

Abstract

This project focused on the goatskin tanning process (Capra hircus), with different levels of oxazolidine in combination with a 6% chestnut was carried out in the fur tanning laboratory of the Facultad de Ciencias Pecuarias. The number of the experimental unit was 24 skins modeled under a completely randomized design using 3 treatments (8, 9, and 10% oxazolidine), with 8 repetitions per treatment. Results suggested that when we use 10% oxazolidine greater resistance to tension (2423.13 N / cm2), the percentage of elongation (68.44%) and lastometry (10.08 mm) were achieved which exceeded the requirements of quality standards in force. The sensations that it provoked to the senses obtain the rating an excellent with a compliance 10% of oxazolidine with a value of fullness (4.63 points), softness (4.50 points), and roundness (4.75 points) that are pleasing both to the appreciation of the manufacturer and consumer because of high-quality leather. Production costs were 1.87; 1.90 and 1.92 for 8, 9 and 10% of oxazolidine respectively, and the highest profitability in the leathers of the T3 treatment (10%) with a benefit/cost ratio of 1.27, taking account of a profit of 27 cents which is acceptable as part of both economic and environmental factors. It is recommended to use the goat tanning process 10% oxazolidine in combination with a 6% chestnut because the material obtained is resistant and with good sensory benefits.
