Anonymous users2024-02-07There 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; Sweaters, down and other delicate materials are not resistant to alkali, and washing with alkaline detergents such as laundry detergent and soap will damage the clothes and cause yellowing, which is also irreversible; 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.
4. Before storing clothes, add more rinsing times when washing clothes to avoid the residue of washing supplies.
5. When preserving, do not come into contact with leather and belts containing phenolic antioxidants; Avoid using brown paper, brown cardboard, plastic film, heat shrinkable plastic film containing phenol antioxidants for packaging and storing clothing.
For yellowed clothing, it can be washed in the following way:
1. Use bright white and brightening laundry detergent to wash regularly machine or hand wash.
For example, the yellowing of clothing does not improve.
2. Soaking. 1) Pure white cotton, linen, polyester clothing: Add 1 bottle cap (40 grams) of blue moonshine white clothes (600g specification) to each half basin of water (about 2 liters), stir well, soak in the clothes for 30min, rinse clean.
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.
The amount of water should make the clothes just soaked, and the net amount of colored clothes and collars should be increased or decreased accordingly according to the amount of water. If the stain remains unremoved after soaking overnight, you can continue to soak for an extended time.
Precautions: White clothes are suitable for white cotton, linen, polyester, polyester cotton, cotton and linen fabrics, do not use silk wool spandex nylon and other non-chlorine bleaching clothes, do not directly use the original solution. Colored clothes are not suitable for clothes that are easy to fade and dry cleaning, avoid touching metal buttons, zippers, metal ornaments, etc. on the clothes when using, and avoid direct sunlight.

Anonymous users2024-02-051. Clothes tend to turn yellow as a whole over time, and sun exposure, including photoaging, is the reason why clothes are easy to yellow.
2. Some sweat stains remain on the clothes, and if they are not washed, they will also appear yellowing.
Laundry detergent is alkaline, and the properties of citric acid itself can be yellowed. Acid-base neutralization also removes some residue from the clothes. Some of them are neutralized, and some of them are cleared. If there are no residual impurities and other contents on the clothes, the clothes will return to their original color and become white.

Anonymous users2024-02-04Clothes will turn yellow when placed in the wardrobe because the clothes have residual sweat stains, oxidation and yellowing, or the fabric of the clothes has nylon and spandex.
Cotton and other materials produce yellowing. Citric acid is available.
Acidic solutions such as acetic acid remove the macula while also brightening the color and softness of clothing. When storing clothes, do not pack them in plastic bags, brown cardboard boxes, and do not come into contact with leather and belts containing phenolic antioxidants. Keep the environment dry, such as Huangmeitian.
During this period, use moisture absorbers and dry clothes regularly. <

It's okay to take it out regularly and let it dry in the sun, but it's more troublesome, and the winter clothes are heavy, and it's hard to dry it once. If you use mothballs, you will have a terrible smell of mothballs in the closet. It is recommended to buy a piece of soap and put it directly in the box or open the package and wrap it in toilet paper and put it in the wardrobe, so that the cabinet is emitted with a faint fragrance, and the effect is very good. >>>More

Please, listen to peroxide??? That's it!!
Bananas should not be eaten as soon as they turn black, especially after being put in the refrigerator, which will speed up the speed of banana blackening! It will turn from a bright yellow to a rotten black. Before you plan to throw them away, I advise you not to "just look at the appearance", why is that?
It must be thought that the quilt is warm, so the popsicle melts off more quickly to diffuse the same heat as the gas, and the high temperature area conducts heat to the low temperature area, and finally tends to be heat balance In fact, the quilt is warm because of the poor thermal conductivity of the quilt in winter, which makes the body temperature and the outside temperature environment blocked, so it will not be lost too quickly, rather than the quilt itself will produce heat because of the body temperature. In the same way, an object with a relatively low temperature outside will naturally not change too quickly in the quilt It is added that even in the quilt, if it is placed for more than 16 hours, it is estimated that the popsicle will turn into ice water.
