Curtición de pieles caprinas con diferentes niveles de glutaraldehído en combinación con Caesalpinia spinosa (tara).

Abstract

The research was carried out in the Tanning Skins Laboratory of Ciencias Pecuarias of the Escuela Superior Politécnica de Chimborazo. The physical analyzes in the Quality Control Laboratory of the FCP with the objective of tanning goat skins with different levels of glutaraldehyde such as (8, 9 and 10%) in combination with (8%) of Caesalpinia spinosa (tare), compared to a control treatment that was tanning with chrome, using a completely simple random design, 4 goat skins of adult animals were used that were acquired in the different markets of the province. It means, a total of 16 skins of adult Creole animals. The statistical analyses used were: Analysis of Variance, Tukey's Test, Regression Analysis and multiple correlation for variables that present significance (P<0.01). The results determined that when applying (9%) glutaraldehyde leathers much more resistant leathers are produced specifically in which has to do with tensile strength (3817.17 N / cm2), lastometry (10.09 mm) and percentage of elongation (51.25%). In addition, in the sensory evaluation of goat leathers tanned with 8% glutaraldehyde, the highest weights of fullness (4.75 points), and roundness (4.75 points) were reported. The highest profitability is achieved by applying higher levels of glutaraldehyde tanning (10%) with a benefit-cost of 1.43 it means, that for each dollar invested you obtain a profit of 0.43 cents. It is concluded that the tanning of goat skins with different levels of glutaraldehyde is an adequate alternative to dispense with the use of universal tannery such as chrome, without deterioration of the quality of the leather. It is recommended to carry out other investigations, tanning with glutaraldehyde and tare at different levels, in order to optimize the resources used.
