Aqueous and Solvent Extraction of Natural Colorants from Tagetes Erecta L., Lawsonia Inermis, Rosa L for Coloration of Cellulosic Substrates. American Journal of Polymer Science and Technology. Vol. 2, No. 2, 2016, pp. 34-39. doi: 10.11648/j.ajpst.20160202.13 Received: September 30, 2016, Accepted: October 20, 2016, Published: December 30, 2016 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.

Introduction At present, there is an excessive use of synthetic dyes, estimated at around 10,000,000 tons per annum [1], the production and application of which release vast amounts of waste and unfixed colorants, causing serious health hazards and disturbing the eco-balance of nature. Currently, ecological considerations are becoming important factors in the selection of consumer goods all over the world. Since the mid-1980s, more interest has been shown in the use of natural dyes and a limited number of commercial dyes, and small businesses have started to look at the possibility of using natural dyes for coloration [2]. Today, in the world of growing environmental consciousness, natural colourants have attracted the attention of everyone. Natural dyes used in food are screened for safety but the information is not known for most of the natural dyes used in craft dyeing and with potentially wider use. There is a tendency to assume that consumable natural products are safer and better than synthetic product because they came naturally. The safety of natural dyes needs to be proved if they are used more widely and in commercial process [3]. Indigo, a blue dye was extracted from the leaves of leguminous plant [4] and turmeric (Curcuma longa), a yellow dye, was extracted from the ground root of Indian saffron plants. Turmeric was the only yellow dye that did not require a mordant to fix it on cotton or silk but is sensitive to light, soap and alkali which reduce its value considerably. Logwood [5] is the most important in black and blue dyeing. It was used on cotton, silk and wood with various mordents for a wide range of colours, but its fastness to light was generally rather poor. Henna (Lawsoniainermis) leaves is an ancient dye, evidence
