Influencia de la calidad del agua sobre el proceso de acabado en húmedo del cuero ovino

Abstract

ln the tanning laboratory of the Faculty of Animal Sciences of the ESPOCH, different levels of butadiene were evaluated in the in the dry finishing of goat leather for automobile upholstery. The number of experimental units was 24 goatskins, and were distributed under a Completely Random Design. The evaluation of the physical resistance of goatskin finishing with different levels of butadiene, recorded the highest responses with the application of 300 g, increasing resistance to tension (1074.24 N/cm2) and dry and wet rub (149.38 and 298.25 cycles), as they surpass with the quality requirements described in the standards of leather destined to the manufacture of car tapestry. The sensorial evaluation of the goat leather establishes the highest marks of naturalness (4.63 points); fullness (4.75 points); and feel (4.88 points), when applying 300 g of butadiene to the dry finish. The cost/benefit ratio infers a higher gain when finishing with high levels of butadiene (300g), since the value was 1.32; or what is the same to say, that for every dollar invested, a profit of 32% which when compared to other similar activities, tum out to be more attractive considering above all that the initial investment and the capital recovery is smaller. It is advisable to apply 300 g of butadiene as it allows the goat skins to pass the fogging tests, and the profits can be increased in the tanning company
