Abstract

A study of Andean cattle skin was performed to determine the variation of skin substance (SP) produced by lime and sodium sulfide during the Liming and Calera stages using four different treatments (T). According to the ASTM D 2868-17, it is important to characterize the raw materials, followed by the tanning processes until obtaining samples of Wet Blue leather. Besides SP analysis and statistical treatment of the obtained data, sensory and physical-mechanical tests were carried out in the post-tanning stages. The results showed that SP at T1 (2.0% lime-2% Na2S) and T2 (2.7% lime-2% Na2S) produced the highest values; 79.5% and 79.3% respectively; with T3 (3.4% lime-2 % Na2S) and T4 (4.1% lime-2% Na2S) yielding 68.4% and 76.1%, respectively.  The statistical analysis of the data evidenced that there is no significant differences between the means of T1 and T2. The results of the physical-mechanical and sensory tests directly relate to the trend of SP consumption in each treatment. The study carried out is aimed to recognize the direct relationship between the skin substance obtained in each treatment and the final product manufactured by the company, referred to the variability of the product to be obtained.
