Is dry cleaning reliable?

But many people doubt whether dry cleaning in dry cleaners is reliable. Some people say that clothes should be washed at the dry cleaners. Is it true?/You don't say. The following small series will teach you how to tell whether dry cleaning is dry cleaning or washing.

Dry cleaning principle of dry cleaners

Every city should have dry cleaners, so do you know the principle of dry cleaning clothes? Dry cleaning is a dry-in and dry-out washing method that uses organic chemical solvents to wash clothes and remove oil stains or stains. Because water does not directly contact clothes in the process of washing clothes, it is called dry cleaning. Principle of dry cleaning: Most stains on clothes are oil or grease attached to dust in the air. Dry cleaning agents for dry cleaning are organic solvents, which are similar to each other and can quickly dissolve oil or grease that makes dust stick to fibers. In addition, adding selected dry cleaning additives to the dry cleaning agent can suspend dust and prevent it from depositing on clothes again. Then, the free dirt can be separated from the dry cleaning agent by filtration or distillation. Water-soluble dirt, such as sludge and restaurant stains, is usually mixed with a small amount of water and dry cleaning additives during dry cleaning; General and modern dry cleaning auxiliaries generally contain enough water, so there is no need to add water. The mixture of dry cleaning additives and water can also be directly used to scrub stains on clothes before dry cleaning. Thus, a small amount of water is introduced into the dry cleaning system in the form of emulsion. This process is usually called pre-decontamination. Because the amount of water added is very small, it is basically maintained in the dry cleaning machine.

How to identify whether clothes have been dry-cleaned?

Many news reports that clothes are washed when they are taken to the dry cleaners, and they are only washed at a high price. As a consumer, how to identify whether clothes have been dry-cleaned? It's simple. Learn from Bian Xiao. Just need a paper towel, put a quality paper towel in the pocket of clothes to be dry-cleaned, write words on the paper towel, and then drop a drop of oil as a special mark to ensure uniqueness. The usual dry cleaning agents refer to tetrachloroethylene and petroleum dry cleaning agents, which are organic solvents and can not dissolve paper towels, but can dissolve grease. But paper towels will definitely wrinkle or even break when they touch water! When taking clothes, if the paper towel is wrinkled or damaged and kneaded into a ball, it means that it has been washed with water. On the other hand, if the paper towel basically retains the integrity of the paper, it means that it has indeed been dry-cleaned.

However, I believe many people will say that dry cleaners will wash clothes first and then dry clean them. Well, if the paper is taken away, we can identify it by its smell. Dry cleaning clothes, because the dry cleaning reagent is usually tetrachloroethylene or petroleum solvent, will leave some slight pungent smell. If it volatilizes well, it won't have these smells. But the clothes washed with water must smell of washing powder, which is very obvious.
