Method of obtaining colorant extract based on plant zhuzgin

Abstract

The invention relates to the field of chemical industry, in particular to the finishing of textile materials. The technical task of this invention is to create a new composition for finishing textile materials using a dye extract of the plant based on leaves, branches and roots with the addition of mordant in the form of aluminum-potassium alum, which allows for high-quality and ecological dyeing of textile materials. The set technical task is solved by obtaining a dye extract based on the leaves, branches and roots of the zhuzgin plant with the addition of a preservative in the form of aluminum potassium alum. The composition consists of aqueous extracts of natural dyes and tinctures, where crushed leaves, branches and roots of plants are used as a dye, 50 g. and aluminum potassium alum 20 gr. as a protravy.
