White and black clothes turn gray when washed

1. Wash with 84 disinfectant: 84 disinfectant can make the color fade, but this method is only suitable for dyed white clothes. Put the gray clothes in hot water, put some 84 disinfectant, soak for half an hour, and gently rub the stained parts of the clothes with your hands.

2. Soap and alkaline water: soak the gray clothes in water for a while, then put the clothes into the soapy water and alkaline water mixed solution, and finally rub them with water to return to their original state.

3. Mix baking soda and vinegar for cleaning: pour baking soda powder into clean water, then pour in white vinegar to mix, then put the gray clothes into the mixed water, and scrub them by hand.

Dark and light clothes and clothes that are easy to fade should be washed separately, and dyeing should be done to prevent them.

When white clothes are dyed, the first reaction of many users is bleaching, and the first products that come to mind are bleach and 84 disinfectant, but not all clothing materials are applicable.

Before applying, it is recommended to know whether the clothing can be chlorinated, and the following are the relevant signs of chlorine bleaching, which can only be applied when chlorine bleaching is available.

Clothing staining is more difficult to remove completely, in addition to the above two products, it is recommended to remove a product to remove color stains: white clothes stain clean, the same is a chlorine bleaching product, before use, it is also important to understand the washing label.

In the dry cleaning process, the dirt on the clothes is removed under the action of mechanical force and enters the dry cleaning oil, some of these dirts are soluble dirt, the other part is insoluble granular dirt, under the action of mechanical force, the surface of the fabric is overcharged due to friction and overcharge, and the insoluble granular dirt will form an opposite electric charge, in addition, because the suspension time of the dry cleaning solvent on the dirt is very short, so if the granular dirt can not be removed in a very short time, Charged granular dirt is then firmly attached to the surface of the fabric in the form of molecular bonds, a phenomenon known as redeposition of dirt, which makes the garment gray and difficult to remove once it is generated.

The solution to this problem is to add a certain amount of dry cleaning oil during the dry cleaning process, which not only has excellent washing effect and emulsifying function, but also has antistatic ability, so that the fabric gives a good feel effect, Many dry cleaners think that as long as frequent distillation can solve the problem, but in fact, on the one hand, it will cause a rise in direct operating costs, on the other hand, years of experience tell us that if you do not use dry cleaning oil, you may never be able to solve this problem, and you can never make customers achieve unexpected results.

Washing colored clothes in dry cleaning may not be obvious as long as the operation is reasonable. However, in the washing of white clothes, the "secondary pollution" in the washing and the "electrostatic adsorption" phenomenon in the drying process will cause the white clothes to be unclean and lose their original luster.

During the washing, the solution is filtered through continuous circulation, so that the dirt in the solution (mainly insoluble dirt) is blocked and separated by the filter, so that the solution is relatively clean. Because the soluble dirt filter cannot be completely filtered and separated, the solution will cause "secondary contamination" of the clothes during washing. In addition, dry cleaning is different from water washing in that dry cleaning is done in the same machine as washing and drying.

The rotational friction between the clothes during drying causes static electricity to be generated on the clothes, so that some of the dirt such as dust and cilia that fall off the clothes will be sucked into the clothes for re-contamination. As a result, the graying of colored laundry is not evident in dry cleaning. However, in the washing of white clothes, the "secondary pollution" in the washing and the "electrostatic adsorption" phenomenon in the drying process will cause the white clothes to be unclean and gray and lose their original luster.

In order to reduce the disadvantages in the dry cleaning of white clothes, in addition to the fact that the characteristics of the solution cannot be changed, we can do a good job in the following aspects to improve the washing quality of white clothes. 1. First of all, do a good job of pre-treatment before washing, remove the mud, oil and pigment stains on the clothes, thoroughly clean all the debris in the pockets of the clothes, and appropriately put in anti-static agents to reduce electrostatic adsorption and remove water-soluble dirt. 2. Keep the dry cleaner and oil circuit clean.

Clean the working oil tank regularly, filter, distill, and clean the button collector and filter frequently. As a practical experience, white and light-coloured laundry is washed in a dry cleaner with a distilled clean solution each time, while the oil circuit is washed on a large cycle (through which the oil passes through a filter). 3. Keep the air duct and washing drum clean, clean the air duct and cilia collection bag frequently, and regularly clean the fluff on the condenser to ensure the quality of the circulating air flow and avoid the re-adsorption of fluff.

I hope mine can help you.

If you can, please give me a thumbs up, thank you.

The reason is that dry cleaning strip detergent has a certain interference with white, and it degrades the color of white, so it is like this.

It may be because you didn't rinse the laundry detergent or detergent when you washed it.

Hot soapy water method

Boil some soapy water, put the dyed clothes in a basin, first soak it in water, then pour the water away, then pour the soapy water that has just been boiled directly into the basin, soak for about ten minutes, and then gently rub it with your hands, and the original color will be restored.

2. Color drifting

The color rinse liquid sold in the supermarket also works well, especially for light-colored clothes that have been dyed for a long time.

Disinfectant

This method is suitable for white clothes, diluted with 84 disinfectant, slightly soaked and cleaned. However, the use of 84 disinfectant must master the dilution ratio and soaking time, which is related to the texture and degree of dyed clothes.

Precautions for washing white clothes

It is important to know that once the white clothes are dirty, they should be washed and dried in time, otherwise they will easily turn yellow. When washing white clothes, if there are difficult stains, you can choose to use bleach type laundry detergent, or soak it in white vinegar to sterilize and remove stains.

1. In the first step, prepare a basin of water and set it aside, see the picture below, go to the steps below.

2. In the second step, after performing the above operation, add 1:10 bleach to pure water, and wear plastic gloves to prevent hand injury, see the figure below, go to the steps below.

3. In the third step, after performing the above operation, stir fully and dilute it fully in water, soak the dyed white clothes for half an hour, so that the dyed part is completely restored, see the figure below, go to the following steps.

4. Step 4, after performing the above operation, 15 minutes have passed, put on gloves and gently scrub the stain until the stain is completely wiped off, see the figure below, go to the following steps.

5. In the fifth step, after performing the above operations, rub the clothes in clean water and rinse, see the figure below, go to the steps below.

6. In the sixth step, after performing the above operation, compare before and after washing, and you can see that the clothes have turned back to white, see the figure below. In this way, the problem is solved.

If it is pure white clothes, use 84 disinfectant soaking, half a basin of water and 2 covers of disinfectant water, soak for 1 hour, and then wash it with laundry detergent, if it doesn't work once, soak it a few more times.

If it is not pure white clothes, if it is colored clothes, use color bleaching to soak, the same method as 84 disinfectant water, and if you don't soak it well, you can soak it several times.

If it is severe, it can only be cleaned with 84 detergent, add some 84 to the stained area, and then gently scrub with a soft toothbrush; Dark colors can be washed with colored bleaching water.
