ABSTRACT

 

Today the protection of environment has become a challenge for the chemical industries worldwide, among which textile industry uses a fairly large number of chemicals for dyeing and printing. The pollution problem posed during the production of chemical dyes, releasing toxic chemicals, non biodegradable dyes from effluent and during its usage like the presence of carcinogenic amines and mutagens in Azo-dyes, heavy metals and toxic chemical etc. are the basis of concern. The ecological aspects including Azo-ban enforced by many countries stimulated the entry of the golden era of vegetable dyes. The present study focus on dyeing of cotton fabric with the natural dye obtained from the cultivated Poppy petals (Papaver orientale L.). As a natural mordant, Harra (Terminalia chebula Retz.) is used for the pre - treatment of sample fabric. Three different eco-friendly metallic mordants; alum [Al2 (SO4)3],CuSO4 and FeSO4 are used. Pre-mordanting was done. Aqueous extraction of dye was carried out in the plant material. The light and wash fastness of dyed samples have investigated using gray scale assessment method. The results for dyeings are very encouraging.
