< p > jeans are indispensable to wardrobe, but they are widely circulated online. Jeans are new and old, and the formaldehyde content is very high. They can not be removed for 15 years. < /p >
< p > netizens say that jeans need to be added to chemicals in printing and dyeing, which contains formaldehyde. In order to make clothes more smooth, wrinkle resistant and stronger colors, chemical stereotyping agents containing formaldehyde will be used. Formaldehyde can irritate the skin, which may cause eczema, systemic allergy and even cancer risk. < /p >
< p > how much is the formaldehyde in jeans? A lab bought four children's jeans and an adult jeans in the North small commodity market, and sent them to the Zhejiang a target= _blank href= http://www.91se91.com/ to test the textile /a Testing Institute. < /p >
< p > according to the national basic safety technical specification for textile products, the formaldehyde content of class a products (infant a target= "_blank" href= "http://www.91se91.com/" > clothing < /a >) shall not exceed 20mg/kg, and the formaldehyde content of B products (clothing directly to the skin) shall not exceed that of 75mg/kg, and the formaldehyde content of C products (clothing not directly touching the skin) shall not exceed the amount of formaldehyde. The 5 pairs of trousers for inspection are all classified into B product standard. < /p >
< p > 3 hours later, the test results came out: 5 jeans were all up to standard, of which only one child jeans had formaldehyde content of 51mg/kg, higher than Class A but lower than class B standard, and the other 4 were "not detected". < /p >
< p > "cowboy" a target= "_blank" href= "http://www.91se91.com/" > cloth < /a > like other fabrics, whether there is formaldehyde, which is related to dyeing and finishing. Lou Caiying, vice president of Zhejiang textile testing and Research Institute, said that jeans are indeed possible to contain formaldehyde, but whether they exceed the standard, depends on the production process. So, does the formaldehyde in jeans really disappear for 15 years? < /p >
< p > the experimenters put jeans into professional instruments and then dry them in the natural environment for a day. Again, the formaldehyde content decreased from 51mg/kg to 32mg/kg. < /p >
< p > formaldehyde in clothing will evaporate in a ventilated environment or in everyday wear. Formaldehyde also dissolves in water, and the content of formaldehyde will decrease after washing. The president of the building reminded that many people worry about jeans deformation and wear them for a long time. This is not correct, especially when jeans are newly bought. They must be washed and worn again, which is both hygienic and safe. (< /p >
