Abstract: This paper concern with the evaluation of physical properties of mulberry silk and cotton after printing with ecofriendly natural dyes. Annatto seed use as a new dye source for block print on cotton fabric and mulberry silk with alum and ferrous sulphate as mordant. The annatto seeds were collected and extracted by using alkaline medium. Different printing variables such as dye material concentration; dye extraction ph, dye paste and thicker ratio, viscosity of the dye liquor, fixer concentration, mordant concentration were optimized for making the printing paste. Evaluation of colourfastness and physical properties of the cotton and Mulberry silk block printed fabric was done. The result reveals that annatto can be successfully used for printing of mulberry silk and cotton fabric and has good colorfastness properties and also enhance physical properties of fabrics which can replace synthethic dyes.
