The principle of dry cleaning of clothing, what is the principle of dry cleaning?

The principle of dry cleaning is to wash the clothes with organic chemical solvents, because the solvent contains almost no water, so it is called dry cleaning.

Dry cleaning originated in Paris, France, so people often call it "French dry cleaning". The main feature of dry cleaning is to avoid damage to the fabric of the clothes caused by washing, no shrinkage, no deformation, good color protection, not easy to cause fading of the clothes, soft feel, easy to iron and can thoroughly clean the oil or stains on the clothes.

Dry cleaning is suitable for fabrics that are not washable and fade easily. It has the advantage of preventing the deformation of the fabric fibers and keeping the original color of the fibers, and at the same time can also prolong the wearing life of the clothes. Dry-cleaned clothes also have the special effects of disinfection, sterilization, insect resistance, and easy preservation.

Steps for dry cleaning:

The first step is pre-treatment, which is the stain removal treatment. It is an artificial additive to pre-treat heavily contaminated dirt and stains insoluble in dry cleaning solvents (e.g. juice, nail polish, paint, ink, etc.) without the use of water.

The second step is the main washing. Place the pre-treated laundry in a dry cleaning machine, wash it thoroughly with a dry cleaning solvent and shake (dry) it.

The third step, post-treatment, is mainly aimed at removing residual dry cleaning solvents from the garment and ironing and shaping.

Pros and Cons of Dry Cleaning:

With the development of the chemical industry and the garment industry, clothing fabrics are constantly updated, and many of them need to be dry cleaned, dry cleaning generally does not deform the clothes, it is also very convenient and fast, and it is quite popular, but dry cleaning also has health risks.

Generally, dry cleaners use a chemical with a high chloride content as an active solvent when drying clothes. This high chloride is harmful to the nervous system in humans. Long-term exposure to this chemical is a high risk of kidney cancer.

In the process of dry cleaning, this chemical can be adsorbed by the fibers of the garment, and when the garment is dry, it is released from the garment into the air, which can affect human health.

Joining a dry cleaner requires a store to rely on, but compared to other industries, the store of a dry cleaner does not need to be too large, and it only takes about 30 to join a small dry cleaner. Joining a dry cleaner requires washing equipment, and the operator of the dry cleaner also needs to master certain cleaning and care techniques, so as to ensure the smooth and continuous operation of the dry cleaner.

Dissolve stains on clothing with organic solvents.

Dry cleaning works by washing clothes with organic chemical solvents.

Since the solvent contains almost no moisture, it is called dry cleaning. Dry cleaning solutions can dissolve and remove grease from clothes. Since the water does not come into direct contact with the laundry during the washing process, it is called dry cleaning.

Analysis of common problems

The buttons are shattered. The buttoned jacket had broken buttons after two dry cleanings. Whereas, dry cleaning is carried out according to the instructions on the maintenance label.

The reason for this is that the plastic used for the buttons cannot withstand the repetitive impact forces with the cage wall during the conventional dry cleaning cycle. Since there is no warning mark on the service label, the responsibility rests with the manufacturer, and if there is an underline on the service label, the dry cleaner is responsible.

The decoration is dissolved.

After four times of perchloroethylene dry cleaning as instructed on the label, the black beaded trim softened and melted, leaving only an unsightly black stain that was present throughout the garment. The reason is that this ornament cannot withstand perchloroethylene washing, and the ornament will dissolve as long as it is immersed in perchloroethylene for 2 minutes. The instructions on the care label are based on conjecture and do not bother to verify its accuracy.

Therefore, the responsibility lies with the manufacturer.

Metal ornaments.

Metal ornaments with fabric wrapped around the neck shrink and wrinkle after dry cleaning. This is because if the decoration is composed of different fibers, the shrinkage rate of each layer should be considered so that the decoration is still flat and smooth after dry cleaning. The responsibility should be borne by the garment manufacturer, who does not have strict operating practices and quality control standards.

Dry cleaning of clothes is the use of solvents to remove grease or stains.

Since the solvent contains almost no moisture, it is called dry cleaning. Dry cleaning solutions can dissolve and remove grease from clothes, such as natural fibers such as wool and silk, which are likely to shrink, deform and fade after washing, but dry cleaning can handle them well, even man-made fibers.

For example, polylipid fiber can also be dry cleaned very clean.

These fibers will still have some oily stains after washing, but they may be removed after dry cleaning. Washing clothes with chemical solvents through osmosis, dissolution, and release to remove grease or stains is called dry cleaning. The so-called "dry cleaning" means that the clothes are dried before washing, and the clothes taken out from the dry cleaning machine after dry cleaning are also dry, but in the dry cleaning process, the clothes are soaked, washed, and dried with chemical solvents in the drum of the dry cleaning machine, and then dried, the chemical solvents contained in the clothes **, and the clothes are dried to complete the entire dry cleaning process.

Dry cleaning is a washing method that has only appeared in the last hundred years. After dry cleaning, the garment will not be deformed, faded, or damaged to the fabric. It also has special effects of disinfection and sterilization.

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.

The principle of dry cleaning is to wash clothes with organic chemical solvents, including a dry-in and dry-out washing method to remove grease or stains. That's why it's called dry cleaning. Because there is no direct contact with the clothes during the washing process.

Dry cleaning involves gently agitating the garment soaked in solvent until dirt and some oily stains are removed.

In addition to general cleaning, so-called dry cleaning also involves solvent dissolving stains, removing stains, and injecting lubricating oil into clothing to eliminate color spots. Stains convert stains into soluble or invisible substances through specific chemical reactions, and biochemical reactions with the participation of enzymes to convert stains into soluble sugars.

No water is used during the entire washing process, so it feels "dry". But in reality, the detergents used in dry cleaning are very similar to water, which can remove dirt without damaging the fabric; Moreover, it will evaporate quickly, leaving only dry clothing.

Dry cleaning involves gently agitating clothes soaked in solvent until dirt and some oily stains are removed. In addition to general cleaning, the so-called dry cleaning also includes dissolving stains and removing stains with solvents; Lubricating oil is injected into clothing to eliminate dark spots; Conversion of stains into soluble or invisible substances through specific chemical reactions; As well as biochemical reactions that occur with the participation of enzymes to convert stains into soluble sugars.

The principle of dry cleaning, how to wash dry cleaning without washing with water.

It's just that you don't have a place to dry your clothes at home, and the dry cleaners can leave a place to dry your clothes.

Dry cleaning is the use of organic chemical solvents to remove stains from clothing. Since the solvent contains almost no moisture, it is called dry cleaning. Washing the garment with chemical solvents through osmosis, dissolution and release to remove grease or stains.

After dry cleaning, the garment will not lose its shape, fade or damage the fabric. It also has special effects of disinfection and sterilization.
