Abstract
Natural dyes obtained from renewable resources of nature such as plant and animal, although natural dyes from minerals of the earth are also known. Extraction of natural dyes from plant sources and improvement of physico-chemical properties of corresponding dyed fabrics through introducing different mordant were reported in this research. Three south Asian plants (Tagetes erecta L., Lawsonia inermis, Rosa L.,) were selected as natural sources for the extraction of natural colorants. Aqueous and Solvent extraction method using water, acetone and ethanol was employed for liquid dyes. With the help of mordents extracted colorants has been installed into the cellulosic fabric. The samples were characterized with spectrophotometer. Physical test were performed under corresponding ISO standards. Results shows excellent coloring ability of extracted colorants thus can be a potential substitute of synthetic dye as a sustainable approach to clean production.
