Desarrollo de una formulación para el proceso de remojo y pelambre utilizando diferentes concentraciones de sulfuro de sodio y su incidencia en la calidad del cuero en la empresa El ALCE.

Abstract

The objective of this research was to determine if there are differences in leather quality by the application of a formulation based on the use of three different concentrations of sodium sulfide in the lime solution process, for this, an applied research of explanatory level was developed using a completely randomized design, taking a quantitative approach to the response variable: leather quality, determined by means of a variance analysis if there were significant statistical differences. Four different treatments were used, whose percentages by weight of sodium sulfide used were 2.5% for the traditional process and 1.1%, 1.5%, 1.9% for the three new formulations that additionally used auxiliary hair removers such as Merpin 8016 (sodium mercaptoacetate), for this, 3 skins were arranged for lime solution treatment while the tanning and dyeing processes were the same. The results showed that the only variable that did not present significant differences compared to the percentage of sodium sulfide used was the resistance to the tension, and it was concluded that based on the measured variables, all the treatments fulfill with the minimum quality levels established according to the standards IUP, and that the most appropriate treatment to replace the traditional one is treatment 3 with 1.9% of sodium sulfide.
