This work aims on the determination of the pre-treatment performance on the basis of scouring and bleaching chemical concentration. Cotton fabrics were pretreated with combined scouring and bleaching at a fixed processing time and temperature with varying amount of hydrogen peroxide and caustic soda. After the operation, the pre-treatment performance, i.e., absorbency, whiteness index, weight loss etc. were measured. It was found that with the increment of both caustic soda and hydrogen peroxide concentration, performance of pre-treatment became better.

Keywords: Scouring, Bleaching, Concentration, Absorbency, Weight-loss, Whiteness index.
