Obtención de cueros de vestimenta lavable utilizando diferentes niveles de polímero Zetestan Gf

Abstract

The objective was to obtain washable clothing leathers using different levels of Zetestan Gf polymer (0, 8, 12, 16%). For which 12 bovine hides distributed in four treatments were processed: in treatment one (T1) conventional fat liquors and fillers were applied (PROVOL BA fat, Sulphuryl HF, Synthol and skirt filler), while in the other treatments, polymer percentages between 8% and 16%. Once the leathers were obtained without dry finishing, the physical-chemical-mechanical quality tests were carried out: tensile strength, lastometry, elongation percentage and bulk density, as well as the sensory tests of: touch, brightness, fullness and softness. The aforementioned tests were carried out before and after subjecting the obtained hides to a machine wash test method with a common detergent. To determine the best treatment, a statistical analysis of the results in the quality tests was carried out, which consisted of: analysis of variance to indicate if there is a significant difference between the treatments, determination of means to compare means with a level of 95% confidence, multiple range test to determine the treatments that show significant differences. While for sensory tests the Kruskal-Wallis test was used. The best treatment of the hides before and after washing was treatment four (T4) with 16% Zetestan Gf polymer with profitable production costs. Therefore, for future research, it is recommended to use Zetestan Gf polymer levels greater than 16% in the fat liquoring of bovine hides and to evaluate the quality tests.
