To achieve a clean and bright appearance with a soft texture, laundry must undergo a bleaching wash. After a regular rinse, the temperature is raised to 60°C, and an appropriate amount of bleaching agent is added based on the color intensity, ensuring a consistent color within 7-10 minutes. During operation, the direction of adding the bleaching agent should match the direction of the drum rotation to prevent localized bleaching caused by the agent not diluting with water quickly enough. Before bleaching, the drum should be slightly filled with water to allow for dilution. After bleaching, the residual bleaching solution in the water is neutralized with baking soda (Na2CO3) or sodium bicarbonate (NaHCO3) to stop the bleaching process completely. After rinsing,洗涤剂, fluorescent brightener, hydrogen peroxide, and other detergents are added at 50°C for washing, pH neutralization, and brightening, followed by softening treatment.

Washing can be divided into oxygen bleaching and chlorine bleaching.

Oxygen bleaching utilizes the oxidizing action of hydrogen peroxide under specific pH levels and temperatures to break down the dye structure, thereby achieving the purpose of fading and whitening. Generally, the bleached fabric tends to have a slight reddish hue. Chlorine bleaching is used...NaClOThe oxidation process is used to break down the dye structure, thereby achieving the goal of fading. Chlorine bleaching produces a rough fading effect and is commonly used for washing indigo denim. After bleaching, the water and residual chlorine in the clothing should be neutralized with sodium metabisulfite to stop the bleaching process. Subsequent stone grinding after bleaching is referred to as stone bleaching (BLEACH STONE E).
