How can white clothes keep it from yellowing

There are many reasons for the yellowing of clothes, with the increase of the number of washing, the chemical color agent added before the general white clothes leave the factory will be lost, and the clothes will be yellowed and old. If the yellowing is caused by exposure to the sun or high temperature baking after washing, it cannot be recovered, and it is recommended that the clothes should not be exposed to the sun or close to high temperatures; It is also possible that the residue or stain of the washing product has not been cleaned and has been oxidized and yellowed in the air.

Measures to prevent yellowing:

1. Avoid exposure to the sun.

2. The fabric should be kept dry during storage, and the yellowing of the fabric in the wet state is much greater than that in the dry state.

3. Wash off the stains on the clothes as completely as possible before storing them. In addition to water, inorganic salts, and urea, sweat also contains lactic acid, fatty acids, and a variety of amino acids. Organic matter that has not been completely washed remains on the clothing, and after a long period of oxidation, the color turns yellow.

Sebum is the same as protein stains.

If the stains are not removed after 2 hours, take out the clothes, add bleaching liquid to the basin (add 1 cap to each half basin of water), stir well, put in the clothes and continue soaking, and the cumulative soaking time does not exceed 6 hours.

2) Clothes or colored clothes made of other materials: pour a small amount of water (about liters) into the basin, measure the color stains of colored clothes and collar (60g each) with the caps of blue moonshine colored clothes (600g specifications), add them to the water, and stir well. Soak in laundry overnight and rinse well.
