There are many reasons why matte rayon clothing turns yellow.

1. As the washing frequency of matte rayon clothing increases, white clothing is prone to yellowing and aging. It is recommended to use bright white and brightening laundry detergent to clean clothing. The unique color adjustment technology can make white clothing cleaner and colored clothing more vibrant;

2. Washing product residues or stains (such as sweat stains) that have not been thoroughly cleaned may cause oxidation and yellowing in the air, or moisture may cause yellowing.

3. Wool, silk, and other alkali resistant fabrics that are washed with laundry detergent, soap, etc. can cause yellowing and cannot be restored. It is recommended to use a neutral detergent for cleaning;

4. After washing, exposure to the sun or high temperature scalding can cause yellowing, which cannot be restored. It is recommended not to place clothes in the sun or near high temperatures;

The yellowing in the latter two situations is irreversible. The yellowing in the first two cases belongs to the problem of color stains, as stubborn color stains have high adhesion to clothing fibers and are difficult to clean with conventional detergents.

The treatment methods for fabrics of different materials and colors are different, as follows:

1. Dissolve the brightening and brightening laundry detergent in water, dilute and stir well, put it into the clothes, and clean the entire body thoroughly

If the yellowing phenomenon of matte rayon clothing still does not improve

2. Soaking

(1) Pure white cotton, linen, and polyester clothing: Add blue moonlight white clothing stain (600g specification) 1 bottle cap (40g) to every half basin of water (about 2 liters), mix well, soak in the clothing for 30 minutes, rinse thoroughly.

*If necessary, the soaking time can be extended appropriately. If the color stains are not removed after 2 hours, take out the clothes and add white clothes to the basin (add 1 bottle cap for each half basin of water). Stir well, then put the clothes in and continue soaking. The cumulative soaking time should not exceed 6 hours.

(2) Colored and other materials of white clothing: Pour a small amount of water (about 0.5 liters) into the basin, and use a blue moonlight colored clothing stain clean (600g specification) bottle cap to measure the colored clothing stain clean and collar clean. Add 1.5 bottle caps (60g each) to the water and mix well. Soak clothes overnight and rinse thoroughly.
