Children's socks are socks that are specially designed and manufactured for children, and these socks are usually smaller, softer, and have better breathability and comfort than socks. Children's socks on Amazon need to do CPC certification. Amazon's requirement for CCPC certification for children's products is based on consumer protection and compliance with relevant regulations.
CPC test for children's socks:
1. Fiber content testing: Fiber content is an important item in textile testing, which reflects the real material composition of the product. Standards and methods for testing fiber content vary from country to country, but are broadly the same. In the detection process, it is necessary to use microscopy, combustion method, dissolution method and other methods to identify the fiber type, and calculate the fiber content percentage.
2. Colour fastness testing: Colour fastness refers to the degree of fading of textiles under external factors (such as friction, washing, perspiration, etc.) during use or processing. Socks with poor color fastness are easy to fade during wearing or washing, which not only affects the appearance, but also may cause irritation to **. Therefore, color fastness is an important test item in CPC testing. Socks are usually tested by rubbing, washing, etc., to observe their color changes.
3. Formaldehyde content detection: Formaldehyde is a common textile finishing agent, which can improve the wrinkle resistance, waterproofness and other properties of products. However, excessive formaldehyde can cause harm to human health, such as irritation**, allergies, etc. Therefore, in the CPC test, it is necessary to test the formaldehyde content of children's socks to ensure that it meets the limit requirements of the country or region.
4. pH value detection: pH value is an important indicator to reflect the pH of textiles. The pH value of the human body is weakly acidic, and if the pH value of the textile is too different from the pH, it may cause irritation or cause disease. Therefore, in the CCP test, it is necessary to test the pH value of children's socks to ensure that it meets the pH requirements of the human body.
5. Detection of decomposable carcinogenic aromatic amine dyes: decomposable carcinogenic aromatic amine dyes are harmful chemicals, and long-term exposure may cause harm to human health. In children's socks, this dye may be used in processes such as dyeing or printing. Therefore, in the CCP test, it is necessary to detect the decomposable carcinogenic aromatic amine dyes in children's socks to ensure that they meet the national or regional limit requirements.
It takes about 5-7 working days for children's socks to be tested for CPC.
