The method of dry cleaning clothes in a dry cleaner is as follows:

The first step: pretreatment, which is stain removal. It uses artificial additives to pre-treat heavily polluted dirt and stains that are insoluble in dry cleaning solvents (such as juice, nail polish, paint, ink, etc.).

The second step: main washing, put the pretreated clothes into the dry cleaning machine, wash them thoroughly with dry cleaning solvent and spin (dry) them.

The third step: post-processing, the main purpose is to remove residual dry cleaning solvent and ironing and shaping from the clothes.

Types of dry cleaning solutions

1. Chlorinated hydrocarbon synthetic solvent, the more commonly used is tetrachlorethylene (PEKCRO), which is safe and has strong degreasing and decontamination capabilities, but it It has a strong corrosive effect on metals. In addition, it has a strong dissolving effect on plastic, nylon and other products, so such accessories (such as buttons, etc.) must be removed during washing.

2. Chlorine-fluorine solvents, the typical representative of which is trichlorotrifluoroethane (CFC-113), etc., which are non-toxic, non-flammable, non-corrosive to rubber and mostly chemical fibers, and have good cleanliness higher than tetrachlorethylene.

3. Hydrocarbon solvents, that is, petroleum solvents, have good washing effects. Clothes washed with such solvents will have no odor that is common in perchlorethylene washing. Nowadays, with the development of science and technology, dry cleaning owners are increasingly favored.
