COTTON DYED WITH YUCUSHAPANA NATURAL PIGMENT USING DIFFERENT MORDANTS

Abstract

This project is part of the research on the transformation of natural resources running in the Faculty of Chemical Engineering at the UNCP. In order to evaluate the potential for staining dye obtained from the forest species yacushapana (Terminalia oblonga) in the implementation of staining of cotton. The Peruvian jungle has a rich vegetation, including plants with active substances such as flavonoids dye, xanthones, quinones, carotenoids, etc., Substances that can be used in cosmetics, food and textiles. This project investigated the tree species with potential for use in the textile industry in the dyeing of fibers. Today the native communities of the low jungle of the Ucayali region, using aqueous dyeing extracts of plant diversity for the dyeing of the fibers used in making variety of clothing and bedding. The above aqueous dyeing extracts are obtained from an empirical way so they have a very low half-life and limited availability at certain times of year as the results of this project will be to advise entrepreneurs in the textile industry in extraction, drying, preservation and application of natural dyes. Formerly dyeing extracts of plants used for the dyeing, clothing, food coloring and so on., Which ceased to be made to appear artificial colors. However, over the years has found that artificial colors can cause disease in humans, so research is needed to remove and reapply the natural dyes. Was extracted and characterization Yacushapana natural dye, then applied in the dyeing process of cotton fabrics pre-etched, resulting in different colors according to mordant used, which are as follows: Light brown with aluminum sulfate, pale yellow copper sulfate, clear yellow zinc sulfate. and dark yellow iron sulfate.
