Why do white clothes turn yellow?

In our lives, we have almost all bought white clothes. White clothes look particularly good to wear, but they are more troublesome to wash. At the beginning, we can wash them carefully, but gradually we don’t care about it anymore. After a long time, we will find that the color of the clothes is no longer the same as when we bought them. The color has begun to turn yellow. So what causes the white clothes to turn yellow?

There are many reasons why clothes turn yellow. With the increase in the number of washes, the chemical colorants added to white clothes before leaving the factory will be lost, and the clothes will turn yellow and become old. It is recommended to use our company's brightening and brightening laundry detergent to wash clothes. The unique color conditioning technology can make white clothes whiter and colored clothes brighter. If the yellowing is caused by exposure to the sun or high temperature after washing, it cannot be restored. It is recommended that clothes should not be exposed to the sun or near high temperatures. It may also be that the detergent residues or stains are not cleaned thoroughly and are oxidized and yellowed in the air.

Measures to prevent yellowing:

1. Avoid exposure to sunlight.

2. Fabrics should be kept dry during storage. Fabrics will turn yellow much more when wet than when dry.

3. Wash off stains on clothes as completely as possible before storing them. In addition to water, inorganic salts and urea, sweat also contains lactic acid, fatty acids and various amino acids. Organic matter that is not completely washed off remains on clothes and turns yellow after a long period of oxidation. The same goes for sebum and protein stains.

4. Before storing clothes, rinse them more often when washing to avoid residues of detergent.

5. When storing, do not let the clothes come into contact with leather and belts containing phenolic antioxidants; avoid using brown paper, brown cardboard, plastic film, heat-shrinkable plastic film containing phenolic antioxidants to package and store clothes.

After we understand the reason, we must avoid it, so that our white clothes will be more vivid and beautiful. But what we need to pay attention to is that when putting white clothes away, it is best not to put them together with some discolored clothes, otherwise they will be stained with other colors over time.
