Why can't the white clothes fade?

Wash at 25~35℃, and wash separately from other clothes. The most important thing is colored clothes. When drying, it is the other way around, that is, put the clothes outside inside, not in the sun, and put them in a ventilated place to dry.

Colored fabrics will fade, which is related to dye properties and printing and dyeing process. For example, most dyes are easily soluble in water (especially in soapy water, hot water and alkaline water). Dyes are easy to fade under the action of sunlight when they are wet. If the combination of dye and fiber thread is not strong enough, it is easy to fade when washing.

In order to keep the color of the material, first, wash it frequently and lightly; Second, if you wash with soapy water and alkali, be sure to put some salt in the water (a bucket of water and a spoonful); Third, rinse with water immediately after washing, and don't soak soap or alkali for a long time or leave it in clothes; Fourth, don't expose yourself to the sun, but put it in a cool and ventilated place to dry.

After soaking 10 to 20 minutes, the clothes will appear dark red. Pick up the clothes and wash them with water. Dissolve a little acetic acid in water, and put the clothes soaked in potassium permanganate into the acetic acid solution. The clothes will gradually change from dark red to the original color, and the dyed place will gradually disappear without destroying the original color of the clothes. This method can sometimes be used for yellow clothes.
