There are mainly two kinds of dry cleaners, petroleum dry cleaners and tetrachloroethylene dry cleaners, among which tetrachloroethylene is a toxic solvent, and long-term contact may cause liver damage and even increase the risk of cancer. Because tetrachloroethylene is absorbed by clothing fibers, it can be released from clothes when clothes are dry, indoor air will be polluted, and it may also cause harm to babies.
The United States Environmental Protection Agency defines tetrachloroethylene as an animal carcinogen, but it also divides it into possible carcinogens and possible carcinogens. In other words, whether tetrachloroethylene can cause cancer is still inconclusive. Moreover, dry cleaning clothes will be dried, and tetrachloroethylene will basically evaporate in this process. If you are still worried, dry cleaning clothes can be hung in a ventilated place for two days before wearing.
Although tetrachloroethylene is not easy to remain on clothes, it may cause harm to employees of dry cleaners. Therefore, our country has strict requirements on the concentration of tetrachloroethylene in the air of manufacturing workshops: no more than 200mg/m3. Employees of dry cleaners should have a sense of self-protection and perform their work in strict accordance with the standards required by the state.

Matters needing attention in dry cleaning clothes
1, amount of dry cleaning agent
The decoloration, hand feeling and washing degree of leather clothes are closely related to the dosage of dry cleaning fatliquor. Therefore, leather dry-cleaning fatliquoring agent has strong permeability. It is both a detergent and a fatliquoring agent, which can reduce the influence of dry-cleaning solvents on dyeing fastness. It is generally believed that the leather clothes that have just been dry-cleaned, that is, soft but not sticky, oily but not greasy, are the best dosage.
The amount of smooth leather and suede leather is basically the same. When the dry cleaning machine washes the leather continuously, it is necessary to constantly replenish the leather fatliquoring agent absorbed by the leather. Use as little or no other dry cleaning detergent as possible when dry cleaning leather clothes.
2, the length of time
Dry cleaning time depends on the cleanliness of clothes. It takes 3-5 minutes to clean clothes and 8- 15 minutes to clean dirty clothes. As long as the leather is washed inside, the dry cleaning time is short. If the leather becomes hard after polishing many times, the dry cleaning time can be extended, or it can be dry-cleaned after being treated with leather remover in advance.
Drying temperature Leather drying temperature refers to the actual temperature in the machine, and the actual temperature often has a certain error with the temperature on the thermometer. It must be noted that the drying temperature of leather should not exceed 25 degrees. Washing method of dry cleaning machine for rawhide clothing Raw leather clothing is generally thicker, because they have the characteristics of wear resistance and good warmth retention.
