Abstract

Fabrics (made of Giza 83 variety) of different structures respond­ed differently to dyeing treatments with variant dyestuffs (natural (hen­na), reactive and vat), this differential response did not follow a definite trend. Generally it is concluded that, the natural dye was found to impart the high fastness (C.S.), alkali perspiration (C.C. and C.S.) and dry rub­bing. Further, reactive dye proved to bring about the high reponse to color strength, light fastness, wash fastness (C.S.) and dry rubbing. Like­wise vat dye appeared to have the most positive influence on fastness to acidic perspiration as well as to alkali perspiration and wash fastness.
