There are 4% friends who wear it directly, please consider it ~
The reason is that my friend also mentioned in the comments: formaldehyde residue, testing whether it fades, is more hygienic.
The first is formaldehyde.
Generally, formaldehyde is used for color fixation and wrinkle prevention in garment processing, so it is normal for new clothes to leave some formaldehyde.
Ps: However, the state has specific regulations on formaldehyde residues in clothes, which are explained in detail below ~
Fortunately, formaldehyde is unstable and water-soluble. As long as the new clothes are thoroughly cleaned, most of the formaldehyde on the new clothes can be removed.
As far as formaldehyde is concerned, even if new clothes (formaldehyde residues are qualified) are put on without washing, ordinary people generally have no problem. Even people with sensitive physique will have short-term hazards such as tears, dry cough, sore throat, slight rash and itching at most. Take off your clothes.
However, it should be reminded that if the newly bought clothes have a strong smell of kerosene, fishy smell and benzene, it is formaldehyde exceeding the standard. If there is still a pungent smell after thorough cleaning for several times, it is recommended not to wear it.
Check for fading.
If it will fade, there are the following possibilities:
① There will be some slight floating colors in the printing and dyeing process;
2 dyes prohibited by the state, such as decomposable aromatic amine dyes, can be used for clothes that are easy to fade;
③ The color fastness of clothes is unqualified.
If it only fades a little during the first cleaning, it may be the first case, and the clothes can be worn with confidence.
However, if the fading phenomenon is still serious during the second cleaning, it may be the reason of ② and ③. ② Banning dyes will affect health; ③ It will affect the use of clothes, and it is not recommended to continue wearing them.
Washing is more hygienic
Don't give examples of how many people have touched, tried on or eaten the gray clothes displayed in the store. In other words, the clothes that have just left the warehouse have passed through many people's hands in the production process, and you don't know how long the seemingly clean clothes have been in the warehouse.
Therefore, newly bought clothes, whether in direct contact with the skin or not, had better be cleaned before wearing.
We are divided into two situations:
Direct over washing
Just once in the water? Or do you need some detergent? Or rub it repeatedly? There are the following points to note:
The water temperature should not exceed 40℃
In fact, it is best to clean it with clean water at room temperature. If the clothes are made of viscose, polyester, acrylic, cotton and so on. We should pay more attention to the water temperature. Clothes are easily deformed when the water temperature is high. You can't wear new clothes directly if you don't wear them ~
Do you want to rub it, rub it?
This depends on your preference. Generally, new clothes are soaked in water for about half an hour, and then washed with clear water several times, which can effectively remove residual formaldehyde.
Do you want to add laundry detergent
Yes, but neutral laundry detergent or soap is recommended. No, no problem. Cleaning with professional in addition to formaldehyde detergent is also effective.
Do you want to expose yourself to the sun?
Not all materials are suitable for clothes, such as silk, nylon fabric and viscose fiber. Can't be exposed to the sun after washing, suitable for drying in a cool and ventilated place. Pay attention to reverse drying for dark clothes.
Most clothes can be washed directly.
For example, light spring clothes.
But it is very troublesome to wash winter clothes and cotton-padded jackets once.
What should I do?
You can also air it.
If thick clothes such as coats and down jackets are really troublesome, they can be dried in a ventilated and cool place for two or three days, and most of the formaldehyde can be removed.
If you still feel that you don't wash and your clothes are not clean, there is another small way to be lazy:
Before hanging for ventilation, take a vacuum cleaner to make a spa for new clothes, or wipe them with a clean wet towel. The dust removal effect should not be too good ~
Of course, I don't mind that the clothes may be damaged. Local tyrants can just throw away the washing machine (down jacket can't be machine washed, it may explode! ! ! )。
Ps: Whether it is a coat or not, please don't be lazy and wash it by hand with clear water.
Washing new clothes is very important.
But how to choose safe new clothes?
It is also crucial.
① Look at the label.
The clothes of regular manufacturers are marked with formaldehyde content or safety category, which is divided into three grades: A, B and C.
In the National Technical Specification for Basic Safety of Textiles, the allowable limit of formaldehyde content is specified:
● Class A products: baby products (diapers, diapers, underwear, bibs, pajamas, gloves, socks, underwear, coats, hats, bedding), whose formaldehyde content must be less than 20 mg/kg;
● Class B products: the formaldehyde content of products (bras, abdominal belts, knitted underwear, shirts, trousers, skirts, pajamas, socks, sheets and quilts) that directly contact human skin must be less than 75 mg/kg;
● Class C products: sweaters, coats, skirts and trousers that do not touch the skin, and interior decorations (tablecloths, curtains, sofa cover, bedspreads and wall cloths), with formaldehyde content less than 300mg/kg.
So when choosing clothes, look at the label to see if the formaldehyde content of the clothes you buy meets the safety category.
For example:
2 look at the color.
Especially underwear, it is best to choose light color. The darker the color, the more dyes are used.
3 look at the pattern.
Avoid the pattern of offset printing. Offset printing is a printing and dyeing method chosen by many small factories, which has low cost, strong paint flavor and formaldehyde may exceed the standard. In addition, the pattern of offset printing will crack and degum after cleaning several times, which will affect the beauty of clothes.
④ materials
It is best to choose natural fiber products such as pure cotton and pure hemp.
The most important thing is that it is more secure to choose clothes of regular brands or sources. Although some brands are found to be unqualified from time to time, to be honest, it is better than clothes of unknown origin.
Before ending, Wei has to say a little rumor.
Many friends around me have told Wei that new clothes, especially jeans, should be soaked in salt water, which is not easy to fade ~ but when Wei did this, she found that salt water soaking was useless at all.
Although, in the process of clothes fixation, manufacturers will add some industrial salts to improve the fixation rate of dyes, but fixation is more than adding salt. Manufacturers will also add alkali, reducing agent, leveling agent, etc. And these many substances can work together to fix the color.
On the one hand, the salt in our family is different from industrial salt, and on the other hand, it is impossible to achieve the effect of color fixation by adding some salt and lacking other substances.
Therefore, it is useless to wash clothes without adding salt and other condiments.
