Washing clothes often has the problem of color fading, while dry cleaning clothes are relatively less prone to color fading. The dyeing process of most textiles is completed in water, which means that most dyes are soluble in water, and there is basically no water in the dry cleaning process, so the probability of clothes fading is greatly reduced. However, some clothes will fade after dry cleaning, which may be caused by adding a small amount of water in some dry cleaning processes and the special printing and dyeing process of clothes.
Secondly, washing clothes is easy to deform clothes, while dry cleaning clothes can protect clothes fibers. This is because water will swell the fabric of clothes, and detergent will also penetrate into the fabric during washing. If the detergent is not completely removed and remains in the fabric of clothes, it will corrode the fabric and probably deform the clothes, while dry cleaning with organic solvents will not have this problem.
But not all fabrics are suitable for dry cleaning, such as pure cotton clothes, artificial leather clothes and down jackets. Therefore, when dry cleaning, the clerk will usually confirm the fabric composition of the clothes with the customer.
Dry cleaning is harmful to health:
The list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization has been preliminarily sorted out for reference, and dry cleaning (occupational exposure) is on the list of Class 2B carcinogens.
Generally speaking, dry cleaners use high chloride chemicals as active solvents when dry cleaning clothes. This high chloride is harmful to the human nervous system. Long-term exposure to this chemical is likely to lead to kidney cancer.
In the process of dry cleaning clothes, this chemical will be absorbed by the fibers of clothes, and then released into the air from clothes when clothes are dry, thus affecting human health.
Many people don't know that dry cleaning will release harmful substances, so when they get their clothes back from the dry cleaner, they either wear them immediately or put them in the closet. In fact, this is very unscientific. The result of taking clothes back and wearing them immediately is that harmful substances on clothes can't be released immediately, so it directly hurts the body.
