Abstract This paper examines the effectiveness of sericin to improve color uptake of acid and reactive dyes on polyester fabric. A 100% polyester fabric was produced with 3 pick density namely 60x60, 60x54, 60x48 and subjected to pre-treatment of 15%, 25% sodium hydroxide. Sericin was extracted from cultivated silk cocoon by boiling them under pressure and applied on pre-treated polyester fabric using pad-dry-cure process. Glutaraldehyde and magnesium chloride were used as cross-linking agent and catalyst respectively. Three different shades of both the dyes were observed for their color strength (K/S value). It was noticed that a highest color strength value of 30.67 was found for acid dye and 38.83 for reactive dye with 25% alkali treatment. The results revealed that the presence of sericin in the polyester fabric makes it possible to dye using acid and reactive dye with bright colors.
