What is the difference between clothes abc class? Are category C clothes bad? C-type clothes are not bad, but they can only be worn outside.
Category C is a standard for textiles that do not directly contact the skin, such as thick coats, down jackets, thick pants, etc. worn in winter. Therefore, according to the latest basic safety technical specifications for products, specific regulations have been formulated on the pH value of formaldehyde content. It is best not to have direct skin contact with category C clothing. The reason for using this standard is because the fabrics of clothing or textiles may contain harmful substances, such as formaldehyde, decomposable aromatic amines, and excessive amounts of these substances can cause certain diseases, such as human leukemia, for a long time. Therefore, according to the closeness of skin contact, they are strictly divided into type A, type B and type C.
Category C clothing will not cause great harm to the human body, but the only requirement is that it cannot directly contact the skin. If it’s a jacket, you can wear it.

Category B is a product that directly contacts the skin, mainly referring to textiles that are in direct contact with human skin in most areas when worn or used. For example: vests, shorts, cotton sweater pants, shirts, pants, bellybands, sheets, etc. The formaldehyde content is ≤75mg/kg, the color fastness to water, perspiration and dry rubbing must be ≥ level 3, and the pH value is allowed in the range of 4.0-7.5.
Category C are products that do not come into direct contact with the skin, such as sweaters, coats, skirts, curtains, bedspreads, wall coverings, padding, linings, etc. . The formaldehyde content is less than or equal to 300mg/kg, the color fastness to water, sweat stains and dry rubbing must be above level 3, and the pH value should be in the range of 4.0 to 9.0. All three types of products do not require special odors, and fabrics that break down aromatic amine dyes under reducing conditions are prohibited.
