Obtención de napa para calzado femenino con la aplicación de diferentes niveles de ester fosfórico

Abstract

In the tannery laboratory CIIP – FCP –ESPOCH, the effect of different levels of different levels of phosphoric ester plus the addition of 2% lanolin oil will, in the lubricating goatskins, divided into four treatments were evaluated, and 8 repetitions, distributed under a completely simple random design. The result inferred that by using 10% phosphoric ester greater to voltage (2777, 87/ cm2) is achieved according to the IUF6 standard, and higher resistance to dry rub (175 cycles), standard IUF 450, while 11% of ester provides higher elongation percentage (121, 56 N / cm2), far exceeding the permissible limits in international leather. The phosphoric ester when applied in lubricating the goatskins 10% (T1), the weight of the skin, it gives good physical strength sensory benefits for the development of women’s footwear that meet the requirements and specification of the technical standards set in order to obtain a high quality material. The highest sensory ratings with 10% phosphoric ester with a softness (4, 88 points) and roundness (4, 50 points), equivalent to an excellent rating according to the proposed by Hidalgo, L. (2016), but most infilling (4,50), shown with 13% phosphoric ester. The higher cost benefit ratio was 10% when using ester with 1, 54; this means that for every dollar invested a profit of 54% is expected.
