What is the basis for distinguishing between Class B and Class C of clothing safety technology? How do you know what clothes are in direct contact or not?

Clothing safety technical categories are classified according to the formaldehyde content in clothing.

1, the standard of grade A is ≤20mg/ kg, which belongs to baby products.

2. Class B is ≤75mg/ kg, which is in direct contact with the skin.

3. Class C ≤300mg/ kg. Products that are not in direct contact with the skin.

Generally, the label of clothes will be marked as Class A, Class B or Class C. If it does not meet the technical requirements, it is recommended not to buy it.

Products that are not in direct contact with the skin should at least meet the technical requirements of Class C products, among which hanging decorative products such as curtains are not tested for color fastness to perspiration.

The Safety Technical Specification for Infant Textile Products stipulates the safety technical requirements, test methods and inspection rules of infant textile products.

Dai Hong, director of the Industry Standards Department II of the National Standards Committee, said that in view of the particularity of infants and young children, the standard further improved the safety requirements of infant textile products on the basis of the original textile safety standards, and the safety requirements were comprehensively upgraded.

In terms of chemical safety requirements, the standard increases the limit requirements of six plasticizers and two heavy metals, lead and cadmium. In terms of mechanical safety, the standard specifies the ropes in different parts of children's clothing, such as head and neck, shoulders and waist, and requires that no ropes are allowed in the head and neck of infants and children under 7 years old.
