Use of Aqueous Crosslinker in Obtaining Reechato Leather

Cortez A, Ru

Abstract: This research was carried out at the Polytechnic School of Chimborazo in the tanning laboratory, with 42 skins of criollo sheep with similar characteristics, distributed in 3 treatments with different levels of aqueous crosslinking agent 30g 40g and 50g respectively, with 14 replicates, for A physical evaluation was carried out, where wet strength, dry rub resistance, and tensile strength were determined. Sensory evaluation, where it was determined power of coverage, softness, brilliance. The correlation between variables was evaluated. Economic evaluation in which the cost of production and profitability were established. Working with 50 g of aqueous crosslinking agent, the best sensorial evaluations were obtained covering power (4.86 points), softness (4.86 points) and brightness (4.71 points), over 5 reference points and with excellent ratings according to the Sensorial scale proposed by Puente, C. (2011).
