DYEING THE COTTON WITH EXTRACT OF ONION PEELS, WALNUT SHELL AND (TANACETUM) TANSY

Natural dyes are attracting increasing attention around the world due to the impact of synthetic dyes on the environment. In this study, 100% cotton fabric was dyed with rich extracts of onion peel, walnut shell and (tanacetum) tansy and combined with some mordants. The coloring of natural dye and the effect of various mordants during simultaneous dyeing with natural dyes were researched. The results showed that natural dyes gave light tones to the fabrics without mordant except onion peel, while the mordanted samples with copper, aluminum-potassium, acetic acids change the colors of the fabric. These extracts, which grow in a large volume in the southern region of Kazakhstan, can be considered as viable alternatives instead of artificial coloring agents. In this study, the experiment was carried out at a temperature of 50-100°C using a minimum amount of mordant with an extract of natural dyes. © 2022 Ivanovo State University of Chemistry and Technology.
