In order to avoid color accidents such as color transfer/bleeding when washing multi-color clothes, the following issues should generally be paid attention to during the washing process:
1. Use manual washing as much as possible, and wash one piece and soak the other. The soaking time should not be too long;
2. Neutral detergent should be used as much as possible (alkaline detergent cannot be used) Strong detergent);
3. The washing water temperature should be as low as possible. In addition, the washing time should be short/the physical force during washing should be moderate, and no hard rubbing/brushing should be allowed. To avoid discoloration of areas with weak color fastness and color cross-fertilization;
4. If possible, use running water (flowing water) for rinsing;
5. It is best to carry out acid treatment (add a few drops of white vinegar to the water) when rinsing for the last time, which can not only neutralize the remaining detergent in the clothes, but also have a certain color-fixing effect;

6. Squeeze the water properly before drying, lay the clothes flat on a white clean bath towel, and then roll up the multi-colored clothes with the bath towel to dry them to absorb possible color bleeding. ;
7. Before drying the clothes, sprinkle edible starch evenly around the dark clothing material to absorb possible color bleeding. Remove the starch after the clothes are dry.
8. If there are leather or artificial leather pieces, before drying the clothes, you should use a hair dryer (low temperature) to blow the pieces from the reverse side of the clothes to speed up drying and avoid color bleeding. .
1. Use vinegar to wash the stained area.
2. Try using bleaching chemicals, such as white cat bleaching chemicals.
3. After diluting it with 84 disinfectant, soak it for a while, but you must master the dilution ratio and soaking time. This depends on the texture of the dyed clothes and the quilt. It depends on the degree of dyeing. It is best to bleach it several times. It is better to have trouble than to over-bleach it.
4. Wash with Amway
5. Potassium permanganate and acetic acid. The method is to dissolve a little potassium permanganate first. Then put the clothes to be rinsed in water and make sure they are fully soaked. After soaking for 10 to 20 minutes, the clothes will turn dark red. Pick up the clothes and wash them with clean water; then dissolve a little acetic acid in the water and soak the clothes that have been soaked in high manganese. When potassium acid-containing clothes are put into an acetic acid solution, the clothes will slowly change from dark red to the original color, and the dyed areas will also fade away without damaging the original color of the clothes. Sometimes they turn yellow after being worn. This method can also be used for clothes.
6. Add washing powder and dishwashing liquid containing a large amount of anionic surfactants to warm water at a ratio of 1:1, and soak the dyed area in warm water for more than half an hour. , and then scrub with your hands. If it is still not clean, put all the clothes in water with a temperature above 50 degrees, add a small amount of washing powder and scrub, and use the fading of the clothes to reduce the color difference of the dyed clothes.

Note: Clothes washed out by bleaching are not good for your health. Bleaching uses a chemical, a special tin compound, which is a very strong chlorine product. If not handled properly, the clothes will burn out. Some use potassium permanganate and then strong oxidation and bleaching with hydrogen peroxide. If it is not white, some also add fluorescent whitening agent. These are very harmful to the human body.
Soak 5 grams of potassium permanganate per piece of clothing at room temperature. The more yellow the color of the clothes, the better. After the color of the strings on the clothes is removed, rinse them twice with clean water, and then use oxalic acid 3 times. -5g + citric acid 3-5g, dilute with warm water, soak and restore with a bath ratio of 1:50, and finally rinse. This method does not apply to silk and pure wool.
Striping method and hanging color method
One is to try to remove the dyeing that has been caught or crossed. This is the so-called stripping method.
One is to try to dye the faded dye back on again. This is the so-called hanging color method.
The operation of these two methods is very technical, and the principles must be mastered before they can be practiced.
Color stripping method; it uses the oxidation, reduction, and emulsification effects of sodium hypochlorite, hydrogen peroxide, bleaching powder, caustic soda, detergent, etc. to remove contaminated color stains and restore the original color of the fabric. There is a way to get damaged.
The hanging color method: It is a method used to deal with the fading of fabrics caused by washing and the color flowers. Add an appropriate amount of glacial acetic acid to the fading water, heat the solution, and the dye molecules will slowly move to the faded parts, restoring the entire piece of clothing to its original color and keeping the coloring uniform. These two methods can effectively deal with the problem of flowers or tresses caused by color pollution.
There are two methods of color stripping, one is the hot bleaching method and the other is the cold bleaching method.
The low-temperature cold bleaching method is generally used because the cold bleaching method is relatively stable and safe.
In addition, high-temperature soap lye stripping method can also be used to make the contaminated color fade evenly, thereby removing the stains. </p
