Carpet is a kind of high-grade decorative bottoming material. It is widely laid in commercial, office and exhibition. According to statistics, in modern hotel office buildings, carpet laying accounts for more than 60% of the total area. Nowadays, with the improvement of people's living standards, more and more families have been renovated. Among the many floor decoration materials, the carpets are rich in luxury, comfortable in the foot, moisture-proof and moisture-resistant, etc. More and more use in the decoration, but in people's use, it is also a headache for some shortcomings of the carpet, such as the carpet is easy to dirty and difficult to clean, not easy to collect, easy to fade, not resistant to pressure and easy to leave marks, etc. Here are some ways to clean:
1. Purchase of carpets
The size of the carpet should be the same as the size of the floor to be laid. Color and performance are commensurate with the occasion of use.
For example, the channel should be made of anti-fouling and wear-resistant carpet, and the living room should be of high-grade chemical fiber carpet or wool carpet with soft texture and gorgeous appearance. In general, the quality of the carpet is greatly influenced by the type of textile fiber used, the number and density of carpet piles, and the pile height. Silk and wool have the best overall performance. The high pile carpet is soft but not easy to clean. In addition, the high-quality carpet carpet surface is flat, the blanket body is thin and even, and it can be restored immediately after being pressed gently, and the back of the carpet is not worn. If the backing is to be firmly bonded to the back of the carpet, there is no opening and closing phenomenon. The purchase of carpets should also pay attention to whether the price is reasonable, the price of handmade wool woven carpets is expensive, and the price of chemical fiber needled rugs is low.
2. Structure of the carpet
The first layer: the face screen, usually made of natural fibers and man-made fibers, the surface is loose and soft.
The second layer: the support layer, usually woven into fibers, plays a supporting role, improves the stability of the carpet, and the durability and durability of the surface yarn and the layer material are woven.
The third layer: the sub-layer, generally woven with hemp or fiber, and the supporting layer is firmly attached to the whole carpet structure.
Liner layer: generally a plastic hole-like structure, which is used to separate the carpet from the ground to increase the permeability and elasticity.
3. Problems to be aware of when using carpets
(1) It is normal for new fleece carpets to appear slightly fluffy at the beginning of use.
(2) The surface of the carpet should be protected against sharp scraping and burns.
(3) Most of the carpets have been treated with anti-mite treatment at the factory, and there is no need to place insect repellents to cause damage to the carpet and the human body.
(4) Spills on the carpet should be cleaned in time, and it will be difficult to remove them after a long time.
(5) After the carpet has been laid for a period of time, a large number of bacteria and a kind of cockroach will be mass-produced on it, which directly endangers human health. Therefore, it should be cleaned and disinfected regularly for two to three months.
(6) In order not to bring dust into the carpet area, a dust blanket mat should be placed at the entrance.
In addition, after the carpet is in contact with chemicals, chemical stains or fading may occur. Therefore, the carpet should be contaminated with commonly used chemicals, such as strong detergents and skin care products. In addition, the carpet cannot be directly exposed to sunlight for a long time. There will be fading.
Carpets need to be vacuumed frequently, because dust is trapped in the carpet, causing wear and tear on the fibers, and the color of the carpet is grayed out. In the stairs, halls, corridors and places where the movement is frequent, the dust should be vacuumed two or three times a week. The bedroom should also be vacuumed at least once a week.
4. Carpet maintenance
Once the carpet is laid, it must be cleaned frequently to maintain aesthetics and reduce wear during use. There are two main types of dirt on carpets, one is dust and other particulate matter, and the other is dirt and grease and Other Chemicals. The former can be solved by regular vacuuming or cleaning. For the latter, chemical dissolution is required, and professional guidance is required. If the method is improper, the stains should spread and must be handled with caution.
(1) Carpet stains
A. Distribution of stains and dirt on the carpet level
The multi-layer structure of the carpet makes it easy to bury stains and dirt.
The stains are not only on the surface of the carpet, but also deep into the entanglement of the fibrous tissue.
The lime soil and sand particles infiltrated into the second and third supporting layers, which became hidden dirt and continuously damaged the carpet fibers.
The carpet is continuously rubbed, and the stains and dirt will be buried deeper and deeper.
B. Classification of carpet stains and dirt:
a. Water-based and dry stains, dirt
Most carpet stains are water-based and dry materials, including dust, sand, starch, soft drinks, tea juice, and fruit juice, which account for 80%-85% of all stains and dirt, especially fine dust. Most of the exfoliation of life adheres to the surface of the carpet. Larger dirt particles will slip on the support layer.
b. Oil-based stains and dirt (this includes animal and vegetable oils, cosmetics, shoe polish, ball-point pen oil).
c. Protein-based stains, dirt (this includes blood, vomit, urine, food), these two types of stains, dirt accounted for about 15/20%.
(2) Treatment of specific carpet stains during use
Ways to remove common stains from carpets:
Edible oil stains: Remove with volatile solvents such as gasoline or carbon tetrachloride, and wash the residue with alcohol.
Soy sauce stains: New stains are first brushed with cold water and then washed with detergent to remove them. Chen stains can be washed with warm water, detergent and ammonia, then rinsed with water.
Shoe polish: Wipe off with gasoline, turpentine or alcohol, then wash with soap.
Urine stains: New stains can be washed off with warm water or 10% ammonia solution. Chen stains are first washed with detergent and then with ammonia water. Pure wool carpets should be washed with Citric Acid.
Juice stains: first wash with 5% ammonia solution, then use detergent again. However, ammonia water has a damaging effect on pure wool carpet fibers, so it should be used as much as possible. Generally, it can be cleaned with citric acid or soap, and alcohol can also be used.
Ice cream stains: Wipe with gasoline.
Wine stains: New stains can be washed with water. Chen stains need to be removed with aqueous solution of ammonia and borax. If it is a carpet of wool or silk material, it can be washed with oxalic acid.
Coffee stains, tea stains: Wash off with ammonia. Silk and wool carpets, rinse with oxalic acid cleaner for 10-20 minutes, or wash with 10% glycerin solution.
Vomiting: One method is to wipe with gasoline, then wipe with 5% ammonia, and then wash with warm water. Another method is to moisten the vomit with 10% ammonia water, wipe it with alcohol-added soap, and finally wash it with detergent.
It is necessary to have the correct wiping method to remove the above stains so as not to damage the carpet and expand the range of stains. Therefore, pay attention to the following points when wiping:
1. First wipe from the edge of the stain and gradually narrow toward the center to prevent the stain from spreading outward.
2. Silk and wool carpets should not be washed with ammonia or alkaline water.
3. Oxalic acid is toxic. It should be diluted in warm water when used. Concentrated acid is easy to damage fiber.
4. The force should not be too strong when wiping, otherwise it will damage the fiber tissue and surface.
5. Potassium permanganate is a strong oxidant, which will destroy the color of the carpet and should be used with caution.
6. Turpentine, gasoline and other flammable products, use the cutting and near fire.
7. Alcohol cannot be used on fiberglass.
(3) Cleaning steps
1) Vacuuming: The carpet should be thoroughly cleaned before cleaning for future work.
2) Cleaning: Use the scrubber to perform the correct scrubbing, and add a proper amount of detergent when scrubbing.
3) Water absorption: use a professional water absorbing machine to absorb water, and reduce the amount of detergent contained in the carpet when the carpet is wiped with the floor cleaner.
4) Scrub: scrub with water and add deodorant to the water to remove the odors from the carpet.
5) Water absorption: The water absorption work described above is continued. After the carpet is wiped with water, use a clean towel to dry the water and try to dry the carpet as soon as possible, but avoid sun exposure to avoid fading.
6) 扒 :: smooth the carpet hair with a hoe and roll it out of the hair in the carpet
7) Hair Drying: In order to make the carpet dry quickly, it is necessary to blow dry and dry the carpet with a professional blow dryer. Make sure the carpet is blown dry quickly.

5. Cleaning procedures for several types of carpets
(1) Dry foam cleaning (for pure wool carpet)
1. Use equipment, tools: single-disc scrubber with carpet brush and bubbler, carpet comb or crepe, vacuum cleaner.
2. Use of materials: carpet high foam cleaner.
3. Operation method:
(1) Vacuuming with a vacuum cleaner;
(2) removing stains and spots by wiping;
(3) diluting the carpet foam cleaner into the foaming box;
(4) Handle the edges, corners and places where the machine cannot be pushed by hand;
(5) Washing the carpet with a dry bulb using a single-disc sweeper equipped with a bubbler and a carpet brush;
(6) for a while, then repeat;
(7) Combing the cilia with a carpet comb or crepe, which is very important for the appearance of the carpet, especially the long-staple cotton velvet carpet, and it has the effect of speeding up the drying of the carpet;
(8) Let the carpet hair completely dry;
(9) Use a vacuum cleaner to remove dirt and dry foam crystals.
(2) Water extraction (for chemical fiber carpets)
1. Equipment used: carpet brush, sprayer, water absorbing machine, carpet cleaning machine;
2. Use of materials: carpet shampoo;
3. Operation method:
(1) Vacuuming with a vacuum cleaner;
(2) Dilute the detergent and pour it into the sprayer (it can also be injected into the water tank);
(3) spraying the cleaning agent on the carpet;
(4) After 10-15 minutes of action, the stains are detached from the fibers;
(5) Washing with a scrubber, the operation is to walk backwards so that each operation line has a partial overlap, and at least two extractions are performed;

(7) Let the carpet completely dry, in order to speed up the drying of the carpet, you can start the carpet dryer.
Note: Continued use of high concentrations of strong cleaning agents can have a negative effect on the carpet backing and the fibers themselves. Therefore bleach should be used last to ensure the life of the carpet. The trick to prevent stains from becoming scars that are difficult to remove is the quick handling. The liquid spilled on the carpet should be blotted with white soft paper. Spread a few more layers on top, wipe gently, then step on it, repeat this step until the wipe is saturated. Sticky things should be smoothed with smoothing, such as a spoon. Solid or powdered things work best with a vacuum cleaner.
