Curtición de pieles de Cavia porcellus (Cuy) utilizando diferentes niveles de taninos sintéticos para la confección de peletería fina

Abstract

In the Facilities of the Skin Tannage Laboratory of the Faculty of Animal Sciences different levels of synthetic tannin (6, 7, 8 %) were evaluated in the fur tanning process with Cavia Porcellus hair (guinea pig), 48 skins with an average weight of 1.5 kg. each, the experimental units were modeled with a Completely Random Desing (CRD). When tanning the skins of guinea pigs it was determined that the appropriate level to allow the transformation of skin into rotting product is 6 % synthetic tanning, since the material is of high quality for the production of the finest products of fur. The best tensile strength was recorded when tanning with 6 % synthetic tannin (1945.75 N/cm2), and the best elongation percentage with the use of 7 % tannin (89.69 %). The most efficient sensorial characteristics were obtained when tanning whit 6 % of tannin (T1), what has to do with the filling (4.88 points); Softness (4.63 points) and roundness (4.75 points), obtaining a very soft and fall skin of guinea pig flexible suitable for the manufacture of high-end items such as clothing. The use of 6 % synthetic tannin provided greater profitability in the cost benefit ratio, with a value of 1.28. Therefore, the use of synthetic tannin is recommended in an amount of 6 %, when registering the best yields and meeting the quality requirements of the Spanish Leather Association
