Stains or dirt on things that are almost impossible to remove at home are easily removed by dry cleaning. At the same time, the fabric remains intact, and the clothes look like new. Dry-cleaning of clothes is carried out, thanks to liquids that have chemicals in their composition. Solvents are hazardous to human health and the environment, so working with them requires special care. Clothes are cleaned with special equipment - a dry cleaning machine.

Stages of the technological process depending on the type of pollution

Dry cleaning of clothes is a chemical-physical process using effective solvents with different composition. Perchlorethylene (PCE) is the most commonly used clothing cleaning agent. It is also possible to use water and special surface-active liquids - detergents.

In addition to solvents, other chemical materials used for degreasing, stripping and staining are used in cleaning clothes. Liquids are selected depending on the technology (cleaning with water, solvents with the presence of carbohydrates or perchlorethylene), the type of pollution, the material from which things are made.

The stages of the technological process include:

• receiving clothes - this stage is very important. During the reception, the specialist determines the type of material, defects of things, the type of pollution, selects the necessary substances to eliminate stains, processing technology. In addition, a contract is drawn up;
• sorting - at this stage, batches of things are completed for subsequent loading into a special machine that performs chemical cleaning. Sorting is carried out according to the texture of the fabric, the color of things, the level of pollution, because due to individual characteristics, each fabric feels in its own way in the machine. Sorting by color is needed so that the dyes do not move from one thing to another;
• stain removal - this process is also called preliminary cleaning. The process is suitable for the most soiled places on clothing. To remove stains at this level, detergents are used along with solvents. Cleaning is carried out on surfaces to remove stains with local light. Such tables are a surface with a hood located on them. Compressed air and steam are supplied by guns. Powerful airflow combined with water, solvents and fabric washer effectively removes stains;
• dry cleaning in the car - consists in drawing out dirt with the help of solvents from the fibers of the material and dissolving them. Dry cleaning equipment operates in a closed cycle. In the container, perchlorethylene, which has already absorbed the dirt from things, is filtered and passes into the distiller, where it is cleaned. Dry cleaning equipment, in order to protect workers and customers, is equipped with an adsorber. The device absorbs the vapors of solvents formed during drying and, accordingly, removes them from things and the drum;
• finishing operations - basically, the finishing stage consists in ironing. This happens on ironing surfaces with steam, which is supplied from the built-in steam generator. Mannequins and presses are also used.

Subsequently, after ironing is completed, the clothes are checked for the quality of dry cleaning and the products are packed. Sometimes clothes are cleaned if soiling remains.

Pollution occurs on the entire surface or locally. The most noticeable are stains or dust. The stiffness of the material is less visible from salt, which is present in products or sweat. The color changes and an unpleasant odor appears from acid or alkali contamination.

There are many substances with which clothing is contaminated, but some of the contamination is similar to each other. They can be divided into the following groups:

• soluble - these are contaminants that dissolve during degreasing. These include fatty substances, oils, waxes. Such contaminants do not dissolve in water;
• water-soluble - stains are divided into two types. The first type (sugar, salt) dissolves easily in water, the second - partially (sauces, soups). These pollution carry the name - food;
• insoluble - these contaminants are completely insoluble in water or solvents. These include dust, soot, pigment substances. In the process of removing stains from the fabric, dry cleaning is used. The problem is that stains can appear after removal, resorption occurs, causing the grayness of things;
• contamination in small areas of the product, which include lacquer stains, blood, paint, are removed with preliminary cleaning, more often manually using special tools.

In the conditions of dry cleaning enterprises, the factors that affect the ease and quality of removal are the type of contamination of the material, the number and type of stains, and the period of their presence on things.
The cleaning method is selected depending on the type of pollution.

Dry cleaning symbols on labels

Experienced employees of enterprises engaged in professional dry cleaning can easily determine how to clean a thing. In case of difficulty, additional information can be obtained if you pay attention to the labels on the clothes. The circle icon indicates that the product can be dry cleaned, but if it is not crossed out. The English letters located on the symbols mean the following:

• R - perchlorethylene or tetrachlorethylene;
• F - highly flammable;
• A - any;
• W - wet.

One dash in a horizontal position means that the dry cleaning conditions must be delicate. In this case, the restriction of humidity, mechanical influence, temperature conditions is applied.

Two lines placed horizontally at the bottom of the symbol indicate a very delicate handling of the product. In this case, the amount of humidity, mechanical action and temperature is limited.

Dry professional dry cleaning is carried out with any of the solvents with the symbol F. With the restriction of solvents, dry dry cleaning with the symbol P is used. Regular dry cleaning (F) is carried out using hydrocarbons, boiling temperature up to 210 degrees, ignition temperature up to 60 degrees.

(F)s.svg means dry cleaning is allowed. (A).svg - dry cleaning with various solvents is allowed. Wet cleaning (W).svg is a regular wet cleaning, and (W) s.svg is a delicate one. The symbol (W)ss.svg refers to delicate wet cleaning of products.

Clothes, the stains on which cannot be removed on their own with ordinary detergents, must be dry-cleaned using special equipment, solvents, reagents at special factories. Dry cleaning of clothes is a process performed by professionals who effectively clean garments and keep them fresh, new and beautiful.

Dry cleaning of the face is one of the most popular varieties of such a cosmetic procedure. It is highly valued for its ability to prevent acne even in a problematic transitional age, which is accompanied by hormonal changes.

Manipulation perfectly copes with the first signs of aging, and also removes traces of inflammation. The measure works even for the future, reducing the areas of damage to skin imperfections, eventually eliminating them almost completely.

Various recipes are aimed at deep cleansing of contaminated skin. In order for each patient to be able to leave the beauty parlor completely satisfied, doctors have developed several types of such chemical intervention. They are tailored to the needs of people of different ages and skin types. According to the reviews, the first result can be seen immediately after the procedure is completed. Visual changes will please even those who have not previously applied for professional cosmetic help.

Dry cleaning classification

The main factor responsible for the success of the event is the procedure carried out exclusively by a professional in their field. The specialist will be able to choose the best remedy, determining the characteristics of a particular ward, and also tell you how to care for the face after cleaning.

Despite the fact that today there are many ways to do peeling yourself at home, experts advise not to engage in such amateur activities. The risks of developing an allergic reaction, as well as possible individual intolerance to drug components, are too high.

Difficulties will be added by the fact that not everyone at home is ready to follow the protocol clearly, being distracted or trying to save money. This leads to a deterioration in the condition of the skin of the face, up to the formation of pronounced chemical burns. Therefore, only a master of his craft, who has undergone special training and has a specialized medical education, should do this.

Technically, peeling with chemical active ingredients is the removal of the top layer of the skin. This concept includes dead cells, as well as accumulations of sebaceous secretions. Chemical acids are taken as the basis, which, with a careful approach of an experienced person, will not harm the skin.

With maximum cleaning, it will be possible not only to neutralize pollution of any type. With its help, it will be possible to activate the internal renewal process, followed by tissue repair at the cellular level. Such regeneration will have a positive effect on the general appearance, making the treated area look fresher.

Schematically, dry cleaning can be divided into three categories, which differ in the depth of action on the body:

• superficial;
• middle;
• deep.

The first version is based on the use of almond, or. All three of these liquids affect the treated area gently and moderately. Manipulation is great for young people whose regeneration process is still functioning stably. A gentle effect can be achieved due to the fact that the effect extends exclusively to the surface dermatological layer. Together, this guarantees:

• improvement of blood microcirculation;
• neutralization of small wrinkles;
• increasing the level of elasticity;
• skin smoothing.

The most important advantage of the superficial type is the ability of the skin to easily tolerate it without significant consequences or complications after application.

The middle analog acts a little more strongly. For him, use a powerful salicylic or trichloroacetic acid. Their action is more pronounced, acting as a guarantee of a stable result.

Due to its strength, the procedure cannot be used as a prophylaxis. Instead, it is used to solve a strictly defined front of problems, the list of which implies:

• wrinkles;
• decrease in elasticity;
• pigmentation.

In addition to covering the upper layer of the dermis, acids cover deeper levels, reaching the basement membrane. The cleansing technique has a positive effect on non-cellular recovery, and also helps to form new collagen fibers. Due to the normalization of local blood circulation mechanisms, it is possible to restore a healthy complexion.

Here it is worth preparing for the fact that the intervention has a number of side effects. They can only be leveled under the supervision of an experienced cosmetologist, which gives a red light for any attempts to independently conduct a middle cleansing.

The most powerful tool is the depth measure, for which phenol is involved. The price of such a service will be somewhat higher due to the cost of the drug itself, as well as the complexity of the implementation. The action will not take long.

Despite the fact that when considering the face before and after, the difference is colossal, not all doctors are ready to offer their patients such a radical approach. Many people refuse it even at the stage of discussing the best option, since the recovery period of six months is too long.

Deep cleansing is a full-fledged chemical burn, the consequences of which come down long enough and painfully. It is not for nothing that doctors, if necessary, use freon prescribe local anesthesia.

The latter can be problematic in itself if the medical staff did not first perform a preliminary allergy test. Otherwise, the likelihood of possible anaphylactic shock increases.

Manipulation is allowed only in a hospital, which will allow you to urgently provide professional assistance if something suddenly does not go according to plan.

Main indications

Depending on what specific cleaning configuration was chosen by the attending physician, the scope of work will be determined. And although each of the presented categories has its own medical indications, experts have compiled a common list of possible reasons for seeking help. This is about:

• excessive fat content of the skin;
• abundant secretion of the sebaceous glands;
• enlarged pores;
• increased pigmentation;
• wrinkles and wrinkled folds;
• grayish complexion;
• solitary acne and acne;
• inflammation of varying degrees of coverage.

The procedure helps to cope even with the consequences of acne, which is typical for people who, in adolescence, did not want or could not seek help from a doctor. Even uneven skin relief can be leveled if you choose the appropriate cleansing option followed by proper care.

Due to the fact that chemical peels are allowed to be performed on patients from the age of 16, the technique is in consistently high demand. Visitors especially appreciate the preventive goals of the method, which will help maintain skin condition at a good level.

step by step diagram

The doctor will definitely warn the patient that the superficial type of procedure is carried out in a course. Usually three to five sessions are enough, depending on the specific skin type and associated problems. But for a middle or deep analogue, one trip to a specialist is enough, but rehabilitation will stretch over a longer period with many recommendations for supportive care.

Regardless of the type of cleaning chosen, the expert must follow a two-step instruction to implement the plan:

• Preparation;
• direct cleaning.

The first point implies the need to prepare the future front of work for the application of concentrated acid. To do this, you will have to apply creams with a low content of the selected acid for some time, so that the dermis has time to get used to the principle of its effect.

Only after the completion of the previous stage is it allowed to proceed to the main part of the plan. First, the master will perform a preliminary degreasing in order to increase the effectiveness of the measure. Next, an acid mask is applied to particularly problematic areas.

Depending on the spectrum of action of the acid, exposure on the face will vary in time from three minutes to twenty. The final step involves the neutralization of the current composition.

In order for the patient to quickly evaluate the result, it will be necessary to apply auxiliary moisturizing and nourishing medicines, based on the problems of a particular person.

Rehabilitation progress

Since each type of chemical exposure has its own rehabilitation period, which, in addition, seriously fluctuates due to the characteristics of the patient's skin, no one will name the exact recovery time.

The easiest way to heal is with superficial cleansing of the dermis, which will take about three days. But recovery with the middle technique can take almost a month.

To consolidate the result, as well as to avoid possible complications such as a not too pleasant appearance in the early days, experts recommend adhering to medical recommendations. The cosmetologist will definitely advise a suitable moisturizing or nourishing cream that can saturate the damaged dermis with useful substances and moisture in sufficient quantities.

An excellent solution to the problem is the use of thermal water. If you apply it on a regular basis, you will be able to avoid puffiness and provide sufficient moisture.

It is also worth refusing to independently remove the manifestations of skin peeling, waiting for the natural completion of the process. We'll have to wait a little with trips to the solarium and tanning under the sun's rays. It will be necessary to avoid saunas, baths and other rooms where an atmosphere of high humidity and high air temperature is maintained.

Contraindications and side effects

Despite the proven effectiveness of the chemical treatment of the face, it does not always go perfectly. This happens due to a violation of the technology of manipulation, the use of cheap substitutes for high-quality care line products, and also due to a lack of skills of a cosmetologist.

The only good news is that a number of side effects are considered the norm when occurring within the framework of average statistics. Just such signs include moderate swelling, discoloration of the skin or its redness.

Do not be afraid of the manifestation of irritation or a feeling of itching. It is allowed to calm the dermis with special means that the doctor prescribes, but it is strictly forbidden to comb the top layer with your hands. You have to put up with dryness and peeling. Sometimes inconvenience affects mild pain or general discomfort, but in the first few days it is quite a common response of the body to harsh outside interference.

To reduce the likelihood of developing atypical complications, it is extremely important to have time to identify latent contraindications for the procedure. Relative prohibitions include pregnancy and lactation. In the latter case, exceptions are possible after consultation with and beautician together.

Other contraindications include exacerbation of chronic diseases, as well as viral or bacterial diseases. Even the usual sore throat, flu or SARS must first be neutralized, to say nothing of a more serious similar pathology - fever.

It is equally important to take into account the characteristics of the skin of each applicant. If the patient has skin hypersensitivity and a tendency to scarring, then it is better to look for more gentle alternatives.

But diabetes mellitus, nervous breakdown, individual acid intolerance, skin lesions, open wound surfaces and extensive inflammation are absolute contraindications. Chronically high blood pressure and oncological neoplasms of various localization can also be entered here. Until the treatment of the latter is officially over, you should not do chemical peels.

If the patient has moles or other formations on his face, then it is worth choosing some other type of cleaning. Also, a woman should take into account her menstrual cycle. It is believed that some days her skin is more sensitive, which can add to the discomfort during the acid period.

The main procedure for cleaning the skin with a chemical peel is carried out in two stages. On a cleansed and dried face, a mask is applied from the fruit acid that was chosen by the beautician. As a rule, such masks may contain retinoic acid, glycolic acid, lactic acid or pyruvic acid. First, a minimal amount of agent is used to open the pores on the skin of the face.

Next, the beautician uses glycolic acid in a more concentrated form. The main task of this mask is the complete dissolution of the "sebaceous plugs" that accumulate in the sebaceous glands and their ducts. It also helps to get rid of comedones, remove the dead layer of the epidermis.

At the very end, a special moisturizing mask is applied to the face, which helps to tighten the pores and speed up their recovery.

Chemical peel

There are several types of chemical peels, depending on the substance used during the procedure:

1. Cleansing with glycolic acid.
2. Peeling with salicylic acid.
3. Peeling with fruit acids.

They work, in fact, the same way, but if you have dry skin, then it is best for you to stop at peeling with salicylic acid, due to which the “pushing out” of sebaceous plugs will pass for sensitive skin without consequences. If you have normal or oily skin, then a chemical peel with glycolic acid is more suitable for you, which first warms up the skin, and then “stretches” the pores and completely clears them of oil.

Chemical cleaning of the face at home

Chemical cleaning of the skin of the face can also be carried out at home, but for this you can only use special masks with fruit acids (citric, lactic or malic). It is very important to consult with your beautician before using such a tool, as well as carefully study the attached instructions.

Before conducting a chemical peel at home, it is necessary to do a test in advance for the sensitivity of your body to the substances of the mask. If there is no allergic reaction and other contraindications, you can proceed to the procedure itself.

The tool should be carefully distributed over the entire surface of the skin of the face to avoid possible burns. Before peeling, do not forget to cleanse the skin with your favorite cleansing toner or milk. If during the procedure you feel a tingling or burning sensation at the site of application of the mask, it must be washed off immediately with warm water and a special compress (tincture from a string) should be made.

You can use masks for chemical cleaning of the face at home no more than once every ten days. For several days after the procedure, try not to go out in the sun and do not use decorative cosmetics. When buying a peeling product, pay attention to its composition. It must contain such substances: phytic acid, azelaic acid, vitamin C.

There are also several recipes for homemade chemical peels. For example, the following is quite popular: take 40 g of dry bodyagi and make a powder out of it. Add two tablespoons of this powder to a 3% hydrogen peroxide solution and mix well. It is important that the mixture becomes creamy.

If you have oily skin, thoroughly steam your face before applying. Otherwise, just blot it with a damp warm terry towel and dry it. Lubricate lips, eyebrows, skin around the eyes with petroleum jelly and apply the resulting product to the skin with massage movements using a cotton swab. Wait 20 minutes and wash off with warm water. Dry your skin. Apply moisturizer if necessary.

Chemical cleaning of the face during pregnancy

Low acid chemical peels are not contraindicated during pregnancy, but it is best to consult an OB/GYN before doing them. More intensive procedures, in particular those carried out in cosmetology salons, are prohibited for pregnant women, as after them age spots or unexpected skin reactions may appear. It is also worth noting that some types of peels have a teratogenic effect on the fetus (for example, cleaning based on retinoids).

Advantages and disadvantages

The main advantage of dry cleaning of the face is the painlessness of the procedure. The skin is not injured, so after this process there are usually no serious complications. When using fruit acids, the recovery period lasts a minimum amount of time. Many patients do not have any traces of chemical peels on their faces the very next day. In addition, such facial cleansing can give not only a quick, but also a fairly stable result.

Unfortunately, this procedure also has its drawbacks. First, the acid cannot penetrate deep enough into the skin. Despite the fact that the top of the skin will become smooth and shiny, pimples and old marks on it will not disappear. Does not remove dry cleaning and wrinkles, scars, deep scars and strong pigmentation.

Story

For the first time, the use of petroleum products for cleaning clothes was proposed by the owner of the dye house, Jean-Baptiste Jolly (France, 1855). He noticed that the tablecloth in his house became cleaner after the maid spilled kerosene on it. Jolly opened the very first dry-cleaner, where he cleaned clothes with kerosene.

At the beginning, petroleum products such as gasoline and kerosene were used for dry cleaning. Their easy flammability led to frequent fires and explosions. Fire hazard concerns led William Joseph Stoddard, an Atlanta dry cleaner, to invent Stoddard's solvent. Its flammability was significantly less than that of petroleum products.

After the First World War, various chlorinated solvents began to be used - they are less flammable than petroleum products and are better at removing contaminants.

By the mid-1930s, dry cleaning began to use tetrachlorethylene (perchlorethylene) as the ideal solvent standard - it is stable, non-flammable, and excels at removing stains with little or no damage to clothes.

Clothes cleaning process

Modern dry cleaning machine

The dry cleaning machine resembles in its actions a combined washer and dryer. Items to be cleaned are placed in a cleaning chamber (called a basket or drum). This is the center of the dry cleaning machine. In the washing compartment there is a rotating horizontal perforated drum. Solvent is poured into the body of the machine while the rotating drum holds the items to be cleaned.

Depending on the size of the machine, the loading weight of the drum is between 10 and 100 kg of textiles to be cleaned. During the wash cycle, the chamber fills with solvent approximately 1/3 of the volume and begins to rotate along with clothing or other products. The temperature of the solvent should not exceed 29.4°C, as higher temperatures may affect the color of the objects, causing discoloration.

During the wash cycle, new solvent is constantly supplied to the chamber from the working solvent tank, while the used solvent is removed and sent to a filter consisting of a distillation boiler and a condenser. The ideal flow rate is eight liters of solvent per kilogram of dough per minute, although this value may vary for different machine sizes.

Before being placed in the machine, all items must be inspected by the operator for dirt and stains. Depending on the nature of the spots, a certain catalyst can be applied to them. Its use is related to the operator's assessment of the type of fabric and stains. Oil stains (grease or lipstick) usually remove very well with perchlorethylene, while water based stains (coffee, wine or sweat) use catalysts to allow the dry cleaning solvent to emulsify the stains and then remove them. Removal of edible fat stains is done by either of these two methods, but a milder catalyst must be applied to them.

Items to be cleaned should also be carefully checked for foreign objects; accidentally left plastic items (pens, buttons) will melt in the solvent bath and may damage the fabric, so that it can no longer be restored.

Some textile dyes are too unstable (especially red) and will lose color when immersed in solvent, so they should not be immersed with other colors to avoid color transfer. Items to be cleaned should be carefully checked for fabric compatibility with dry cleaning. It is required to carefully study the fasteners; many decorative fasteners are unsuitable for solvent dry cleaning or will not remain intact under the mechanical action of the cleaning process. They will be removed after cleaning or protected with a small padded protector.

Finally, finer items such as feather bedding or rugs with tassels or drapes can be packaged in a perforated bag. The density of perchlorethylene at room temperature is about 1.7 kg/l (70% heavier than water), and due to this weight of solvent, the fabric can tear under the action of centrifugal force during the work cycle if mechanical support is not provided with a bag.

A typical wash cycle lasts 8-15 minutes depending on the type of items to be cleaned and their degree of soiling. Within the first three minutes, the dissolvable stains break down into perchlorethylene and the simple insoluble stains come off the fabric. Dirt that has penetrated deep into the fabric is removed 10-12 minutes later. Machines using hydrocarbon solvents have a wash cycle of at least 25 minutes due to slower dissolution of stains. Dry cleaning surfactant "soap" can also be added. After the washing cycle, the machine starts the rinse cycle - the item being cleaned is rinsed with a new portion of the solvent. The solvent rinse prevents discoloration of garments caused by dirt particles being adsorbed back onto the surface of the garment from the "dirty" working solvent. After rinsing is finished, the machine starts the extraction process. This process recovers the dry cleaning solvent for reuse. Modern dry cleaning machines can recover up to 99.99% of the solvent used in the cleaning process. This cycle begins by drawing solvent from the chamber and accelerating the basket to 350-450 rpm, which separates most of the solvent from the tissue. When there is no more solvent left, the machine starts the drying process. During the drying process, the articles to be cleaned are rotated in a continuous stream of warm air (63°C) which is circulated through the basket, evaporating any traces of solvent left after the rotation process. The temperature of the air must be carefully managed to prevent drying out and damage if the temperature of the items is too high. The warm air then passes through a cooling system where the solvent vapors condense and return to the solvent tank. Modern dry cleaning machines use a closed circuit system where cooled air is reheated and run a second time. This results in a very high solvent recovery ratio. After the drying process is completed, deodorization (ventilation) begins, and the machine proceeds to the process of cooling the products and removing the last traces of dry cleaning solvent by distributing cool outside air over the products, then the air passes through the steam recovery filter produced from activated carbon and resins polymer. At the end of the airing process, dry cleaned items are clean, odorless and ready to be ironed or finished.
