This study aimed to investigate the effect of textile materials on hydrogen peroxide stabilization during bleaching. For this purpose, fabrics made of different fibers types were bleached with the same bleaching recipe. It was found that the fiber type have different effects on the decomposition of peroxide. So it is important to stabilize the bleaching bath considering the fiber type. The highest activation effect was obtained with the wool. Jute fabric also showed the higher rate than the blank bleaching. But cotton fibers had the highest stabilization effect in the bleaching bath.
