Dry cleaning is a dry-in and dry-out washing method that uses organic chemical solvents to wash clothes and remove oil stains or stains. Because water does not directly contact clothes in the process of washing clothes, it is called dry cleaning. Because it originated in Paris, France, people often call it French dry cleaning.
The process of dry cleaning is to gently stir the clothes soaked in the solvent until the dirt and some oil stains are removed. The so-called dry cleaning, in addition to general cleaning, also includes using solvents to dissolve stains and remove stains.
Lubricating oil is injected into clothes to eliminate stains. The stains are converted into soluble substances or invisible substances through specific chemical reactions, and the stains are converted into soluble sugars through biochemical reactions with the participation of enzymes.
Washing steps and methods of dry cleaning:
1. Clean the dust on the surface: after the clothes are dried, pat them with rattan or wooden stick to make the dust come out, and then brush the surface of the clothes with a brush. There is a lot of dust on wool clothes. After brushing with a brush, you can smooth the clothes, put the wringed wet cloth or towel on it and pat it gently with your hand, so that the dust on the clothes will stick to the wet cloth or towel after it pops up, which can better remove the dust.
2. Focus on scrubbing: the dirtiest parts of clothes are collars, cuffs, pockets and other parts. Wipe these dirty parts with dry cleaning agent first, and scrub some dirty and serious parts first.
3, comprehensive brushing: use a small brush or towel dipped in a small amount of dry cleaning agent to brush the whole clothes in turn, the order is sleeves, front, back, collar, and finally brush the clothes lining again. If the lining is much lighter than the cloth, scrub the lining first. When dry cleaning, it should be noted that no matter whether you use a small brush or a towel, don't dip too much detergent at a time, otherwise it will be wasted and the effect will not be good.
4, air drying: after washing clothes, do not wear them immediately, should be placed in a ventilated place to air dry, never exposed to the sun. Because dry-cleaning clothes are mostly high-grade worsted products with natural fibers as raw materials, exposure will accelerate fiber aging, make it lose its elasticity and natural luster, and shorten the life of clothes.
