In the market, street sales channels, under the banner of "factory direct sales" and "inventory sale", sell bedding with bright colors and different patterns. The prices range from tens of yuan to hundreds of yuan (of course, there are more low-cost bedding online). Don't believe it!
With the strengthening of the national health and safety inspection of bed products, those low-cost and poor quality bed products continue to surface and exposure. Carcinogens such as formaldehyde, excessive pH value and decomposable aromatic amines exist in low-quality bed products.
Azo carcinogenic dyes
Low price = inferior! After using azo dyes containing carcinogenic aromatic amines in textiles, the dyes may be absorbed by the skin and spread in the human body during long-term contact. These dyes in the normal metabolism of human biochemical reaction conditions, may occur reduction reaction and decomposition of carcinogenic aromatic amine, cause human disease and induce cancer, and the incubation period may be more than 10 years.
Excessive pH - pruritus, dermatitis
In the process of textile printing and dyeing, a lot of acid and alkali will be used for various chemical reactions, so the phenomenon of pH value exceeding the standard is often encountered. Generally, the pH value of human skin is between 5.5 and 7.0, which is weakly acidic. If the pH value of textiles exceeds the standard, it will damage the weak acidic environment on the surface of human skin, cause pruritus, and make the skin vulnerable to other bacteria, and even cause dermatitis and other symptoms.
According to the national standard, the pH value of infant and textile products with direct contact with skin should be controlled between 4.0 and 8.5, and that of textile products without direct contact with skin should be controlled between 4.0 and 9.0. If the products need to be processed in the subsequent process, the pH value of non final products that must be wet treated can be relaxed to between 4.0 and 10.5.
