Abstract: This paper concern with the use of annatto seed as a new dye source for block print on eri silk fabric 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. Experiment was done to evaluate the colour fastness and physical properties of the eri block printed fabric. The result reveals that annatto can be successfully used for printing of eri fabric and has good colour fastness properties. All printed samples with mordant improve physical properties of annatto dye on eri silk fabric.
