The reason why there are black spots on towels
There are several reasons why there may be black spots on towels. One common reason is that the towel has been washed with dirty clothes or in water that contains iron or manganese. Another possibility is that the towel has been exposed to sunlight for too long, which can cause the fibers to degrade and turn color. In some cases, the black spots may be mold or mildew growth, especially if the towel is not properly cleaned and dried after each use. It is important to regularly clean and sanitize towels to prevent the buildup of bacteria, mold, and mildew, which can cause health problems for those who come into contact with them.
When we use towels for a long time, we may find that they have some black spots on the surface. These black spots are not only unsightly, but also harmful to our health. So, what are the causes of these black spots? How can we prevent them?
Firstly, the main component of towels is cotton, which has good water absorption and breathability. However, cotton is also easy to absorb colorants and pigments. When we wash towels, the colorants and pigments in water will be absorbed by towels, especially in hard water areas. These colorants and pigments will accumulate on the surface of towels for a long time, forming black spots.
Secondly, the use of towels is very frequent, and it is easy to accumulate bacteria and viruses. If we do not clean the towels in time, these bacteria and viruses will multiply quickly, and their metabolites will also accumulate on the surface of towels, resulting in black spots.
Thirdly, if we put damp towels in a damp environment for a long time, it is easy to grow mold. The mold will also form black spots on the surface of towels.
In order to prevent the occurrence of black spots on towels, we should first ensure that we use soft water to wash towels. Soft water has less colorants and pigments than hard water, which can reduce the absorption of colorants and pigments by towels. In addition, we should regularly clean the towels, and wash them with soap or detergent to remove the bacteria and viruses on the surface of the towels. Finally, we should try to avoid damp towels being placed in a damp environment for a long time, and can be hung up to dry after each use to prevent mold from growing.
In addition, if we find black spots on the surface of towels, we should first stop using them immediately. Then, we can use a cleaning agent to clean the towels, or soak them in a diluted bleach solution for half an hour to destroy the bacteria and viruses on the surface of the towels. After cleaning, we should also ensure that the towels are fully dried before being used again to prevent bacteria and viruses from multiplying again.
In conclusion, the black spots on the surface of towels are mainly caused by the absorption of colorants and pigments in water, the accumulation of bacteria and viruses, and the growth of mold. In order to prevent the occurrence of black spots, we should use soft water to wash towels, regularly clean and dry them, and try to avoid damp towels being placed in a damp environment for a long time. If black spots are found on the surface of towels, they should be cleaned immediately and fully dried before being used again to ensure our health and hygiene.
