STUDIES ON THE APPLICATION OF SOME LESS KNOWN ETHNO MEDICINALLY DYE YIELDING PLANTS FOR DYEING IN COTTON CLOTH WITH FOCUS ON CONSERVATION STRATEGIES IN PASCHIM MEDINIPUR DISTRICT, WEST BENGAL, INDIA: A NEW APPROACH 

ABSTRACT

The use of natural dyes has increased during the last couple of decades, looking at the bad effects of synthetic dyes. Natural dyes are considered to have lower side effect, less hazards, less polluting, less toxic and non carcinogenic. The present paper deals with the preparation of natural dyestuff extracted from four dye trx australia yielding plants which is less known (belonging to four families) available in the district of Paschim Medinipur. The extraction of dyes from different plant parts of the selected dye yielding plants was carried out using aqueous solution. Cotton cloth is widely used for this experiment and also used the safe common mordant alum is used for color fastness of dyed cloth. The light fastness, wash fastness and rub fastness test of the dyed material were also carried out. The study focus to on the ethno medicinal value of natural dye yielding plants of this district and to highlight on the use of natural dyes as a source of different color shades using safe eco-friendly mordant. Also put on light It is extremely essential to make a conscious effort on conservation of such natural dye yielding plant species and proper documentation and effort should be made needed to increase the production of natural dyes on a large scale basis in this district, otherwise we are bound to lose vital information on the utilization of natural dyes resources around us.

Key words: Ethno medicinal, Natural dye yielding plants, Cotton cloth, Mordant, Color fastness, Conservation.
