The principle of dry cleaning is equivalent to the basic principle of "purification" in chemistry. It is the organic solvent (perchloroethylene) when the dry clothes are soaked in dry cleaning equipment.
**etc.) also get rid of the oil stains in the clothes, and then go through the process of thinking, spinning, and drying treatment, and the clothes taken out of the equipment are made and very clean. In this way, it does not damage the fabric, the clothes and pants do not wrinkle, and the color does not fade.
The difference between dry cleaners and water cleaning is mainly in the basic principle, different from dry cleaners, water cleaning must be based on the use of water, the soap powder is melted, so that it can be completed with the help of external forces. Dry cleaners rely entirely on mechanical interactions.
At the same time, the washing machinery commonly used in dry cleaners and water cleaning is also very different. Water cleaning actually has a lot of shortcomings, so many more expensive clothes and pants, such as suits.
Or down jackets, long coats or whatever, on the clothes will be marked not to be cleaned with water, the reason is because the damage to the clothes is very large.
The important process of dry cleaners is to clean clothes and pants through some special chemical organic solvents. In the whole process of the dry cleaner, there will be no water in the room, and the process of the dry cleaner is mainly to soak the clothes in the detergent in the dry cleaning equipment, and then reuse the plug-in of the dry cleaning equipment to complete a process of all the dry cleaners, and then go to the dry cleaning equipment to dry the clothes. Naturally, in this process, dry cleaning is the detergent attached to the clothes, which will be completely used and returned home, and cannot cause all the damage to the clothes.
Clothes such as cashmere or silk are likely to become smaller, deformed, and fade after washing, but dry cleaners can solve the problem very well. For example, the oil stains on cotton and woolen clothes are difficult to wash off completely with water washing, and the color fades, and the dry cleaners will solve it very well. Nowadays, the laundry carries out the actual operation of the dry cleaner, there are special dry cleaning equipment, so there is basically no difficulty coefficient, the rapid development of today's society, there are more and more clothes that must be dry cleaned, and the laundry business is also soaring, and now the investment in dry cleaners is a popular project, especially in the dry cleaning industry has been favored by everyone with the advantages of small cost, low cost and good prospects.

1. Dry cleaning principle: Most of the dirt on the clothes is formed by the dust in the air adhering to the oil or grease and then adhering to the fibers. Oils or greases mainly come from the body's secretion of fat, cooking oil, and car exhaust. The function of dry cleaning agents is to quickly dissolve oils or greases that make dust adhere to the fibers.
The addition of a specially selected dry cleaning aid to the dry cleaner allows the dust to be suspended and prevents it from re-depositing on the garment. Then, by filtration or evaporation, the free dirt can be separated from the dry cleaner.
2. Water-soluble dirt such as sludge, food and beverage stains are not easy to remove with only dry cleaning agent. To enhance this decontamination capacity, a small amount of water is usually added to the dry cleaning process, usually with a mixture of water and dry cleaning aids. Modern dry cleaning aid formulations generally contain enough water, so there is no need to add additional water.
A mixture of dry cleaning aids and water can also be used directly to brush stains on laundry before dry cleaning. In this way, a small amount of water is introduced into the dry cleaning system in the form of an emulsion. This process is often referred to as pre-decontamination.
Since the amount of water added is very small, the dry cleaning conditions are basically maintained in the dry cleaning machine, and shrinkage, fading, deformation and all other problems that can be avoided by dry cleaning agents are minimized.
3. The principle of detergent is that the four categories of dirt and the corresponding removal method a soluble in organic agent-solvent-soluble dirt, such as grease, are removed with solvents; b. Water-soluble dirt - water-soluble dirt, such as salt and sugar, should be removed with soap oil; c. Insoluble in solvents, insoluble in water - insoluble dirt, such as dust, metal oxides, removed by mechanical force; d. Local dirt that requires special treatment - stains, inks, are removed on the stain removal table with special chemicals.
The most important thing to join the dry cleaner is to choose a good franchise brand, and if you encounter business risks in the later stage, you can get the greatest help from the brand and reduce business risks. It is recommended to join the dry cleaner industry to open a store, and it is necessary to carefully select the franchise brand from the aspects of the publicity strength, popularity, support ability, and marketing network of the dry cleaner brand. Understand the operation status and model of the dry cleaner brand, and carefully choose the appropriate dry cleaner franchise brand after comparison.

Dry cleaners, as the name suggests, are dry cleaning when washing clothes.
The process of washing clothes in a dry cleaner is to gently stir the clothes soaked in solvent until the dirt and some oily stains are removed. This solvent is 95% perchloroethylene, which is used to remove oil from metal surfaces.
In addition to this, the dry cleaning process also converts stains into soluble or invisible substances; As well as biochemical reactions that occur with the participation of enzymes to convert stains into soluble sugars.
The whole process of dry cleaning is very similar to that of washing, which uses water as the washing medium, with detergent to achieve the purpose of descaling the soiled clothes, and then sewing the appropriate water process, followed by dehydration and drying.
Dry cleaning is to use volatile organic solvents as the main substance and washing medium for decontamination with appropriate water and detergent for the purpose of descaling, and then dehydration and drying, the difference between washing and dry cleaning is that the form of washing and the medium are not connected, but the mode is roughly the same. Since the water does not come into direct contact with the laundry during the washing process, it is called dry cleaning.

The dry cleaner laundry steps are as follows:
1. The front desk staff of the dry cleaner collects the clothes from the customer and sorts them and evaluates them;
2. Check the main stains of the clothes and check the clothes with pockets according to the customer's requirements to see if there are any items left;

Dry cleaning has become an indispensable service in people's daily lives, and it is common for people to send large, unmanageable, and expensive clothes to dry cleaners. According to the principle of dry cleaning machine and the synthesis of raw materials of dry cleaning and detergent products, silk, cashmere and other clothes with excellent texture, as well as some cotton and linen clothing that are easy to shrink, as well as leather and fur clothing, must be dry cleaned. Professional washing can be divided into three main categories:
Dry, wet and washed. Dry cleaning is not dry cleaning, but uses organic solvents to remove dirt from clothes, and it is called dry cleaning because the solvent used for washing does not contain or only contains a little water, and there is no such thing as water penetrating into the fabric fibers.
One of the biggest benefits of dry cleaning is that dry cleaning oil can remove grease and dirt from clothes; Washing, on the other hand, cannot. Natural fabrics such as cardigans and silk garments are very effective for dry cleaning, while such fabrics may shrink, wrinkle, and fade when sent to wash. Dry cleaning of synthetic fabrics such as polyester is still very effective, but washing cannot remove oily dirt from such fabrics, dry cleaning can help restore a fabric to a "smooth as new" state, as long as the laundry has taken a series of measures to prevent shrinkage, color loss and fiber deformation in advance.

What is Dry Cleaning?
Dry cleaning means that during the washing process, the water does not directly contact the clothes, but the clothes are washed with organic solvents, and the solvent contains almost no water. The content of perchloroethylene in the solvent can reach 95%, which can convert stains on clothing into soluble or invisible substances.
Summary: 1. First of all, it is a simple treatment of serious stains on clothes with detergent;
2. Then put the simply processed clothes into the dry cleaning machine, and add washing solvent for comprehensive washing and drying;
