Curtición orgánica e inorgánica de pieles caprinas para tapicería automotríz.

Abstract

The objective of this research was to study the organic and inorganic tanning of goat skins for automotive upholstery. The bibliographic information was collected based on information from the following scientific platforms: Scielo, Scopus, E-book, Science Direct, Dspace Espoch, experimental theses and scientific articles. The variables were: tensile strength (N / cm2), percentage of elongation (%), shrinkage temperature (degrees centigrade), lastometry (millimeters), fullness (points), softness (points), roundness (points). Regarding the evaluation of the physical resistance of the hides, the most appropriate tanning was when using tare, since it is possible to obtain very good classification hides with the highest percentage of elongation (72.12%), and shrinkage, (92.86 degrees centigrade), while the best tensile strength was achieved when using 10% tare plus glutaraldehyde (3407.74 N / cm2), and finally the best lastometry was obtained when tanning with 10% mimosa plus 5% synthetic tannin. The highest sensory scores were reported in the leathers tanned with 18% tare specifically with regard to fullness (4.83 points), on the other hand, the highest value of softness (4.88 points) was obtained when using 14 % tare plus 1% oxalic acid and the best roundness (4.67 points) was achieved when tanning with 14% tare plus 4% glutaraldehyde. The highest economic profitability was recorded when tanning the leathers with 10% tare, since the benefit-cost ratio was 1.34, that is, for every dollar invested, a profit of 34 cents or a profit of 34% is expected. Therefore, it is concluded that by using 10% of Tara a high physical and sensory and economic quality leather is acquired.
