Thus, the pre-treatment process is necessary for polyester fabric ink jet printing. On the other hand, linen, which is a natural bast fibre, has unparalleled characteristics such as a feel of freshness and a magnificent brilliance. It is very hygienic and it imparts an air of satisfaction and style to the wearer (Behera, 2007). With the trend of fashion towards natural, comfortable yet elegant fabrics, linen and linen-blended fabrics have gained prestige and increased reputation. The objective of our work is to improve the colour parameter of ink jet printing polyester and linen fabrics and their blend using eco-friendly method by applying different enzymes.
