Composition of hydrogen peroxide catalyst and application thereof

The invention belongs to the related field of chemicals, and provides a composition of a hydrogen peroxide catalyst. The composition is prepared from the following components in percentage by content: 0.02%-0.05% of manganese inorganic matter, 0.1%-0.2% of acetic acid, 0.05%-0.6% of sodium acetate, 0.05%-1.2% of sodium chloride, and the balance of water; and the total amount of the composition is 100%. The invention further provides an application of the composition as a catalyst for bleaching sulfur dyes. The composition can replace traditional bleaching water, sulfur dye can be uniformly bleached or stripped in a water bath, and the color brightness of bleached cloth is improved. Meanwhile, the whole bleaching process is very safe and controllable, and no smelly bleaching smell is left on a workshop and a product, so that the production environment is improved. Moreover, the bleaching process is short in time, and the destructive power to the cotton fibers or the spandex fibers is reduced, so that the stren
