The Beijing Municipal Bureau of Quality and Technical Supervision conducted a product quality supervision and inspection on the bedding products produced by the enterprises in this city. The inspection shall be carried out in accordance with GB5296.4-1998 "Guidelines for the Use of Textiles and Apparel for Consumer Products", GB18401-2003 "National Textile Product Basic Safety Technical Specifications" and product disclosure and the current effective corporate standards for filing. The inspection items include seven components: the content of the raw materials used in the finished product, the formaldehyde content, the pH value, the color fastness to water, the color fastness to perspiration (acid and alkali), the color fastness to dry rubbing, and the decomposable aromatic amine dye. A total of 53 kinds of bedding products from 29 production enterprises in Beijing were sampled, and 29 kinds of products were qualified. The sampling rate of products was 55%. The main problems found in the spot check are as follows:
1. The decomposable aromatic amine dye exceeds the standard. Textiles and clothing containing carcinogenic aromatic amine dyes can cause harm to the human body. Some small black-hearted workshops use inexpensive decomposition of aromatic amine dyes, which exceed the standard limit of detection of 20mg/kg more than 6 times.
2. The pH value exceeds the standard. Under normal circumstances, the pH of human skin varies from 5.5 to 7.0, which is slightly acidic. The acidic environment of the skin can inhibit the growth and reproduction of certain pathogenic bacteria and protect the skin from infection. If the pH of the textile is too high or too low, it will not only cause irritation to the skin, but also cause the skin to be infected by the bacteria. The national standard GB18401-2003 "National Textile Product Basic Safety Technical Specification" has made clear and strict regulations on the pH value of textile products. The pH value of Class B direct contact with skin should be 4.0-7.5. The pH value of Class C non-direct contact with skin It should be 4.0 to 9.0.
3. Color fastness does not meet the requirements of national standards. The national standard GB18401-2003 "National Textile Product Basic Safety Technical Specification" has strict requirements on the color fastness of textile products, and specifies the color fastness of Class B direct contact with skin and Class C non-direct contact skin ≥ 3 (water and acid resistance) Perspiration, alkali-resistant perspiration, dry rubbing fastness). In this spot check, two products showed low color fastness. The unqualified index not only caused the textiles and garments to fade and stain, but also affected the wearing effect of the garments. In the process of wearing, the dyes may be transferred from textiles to humans. On the skin, under the biocatalysis of bacteria, it becomes a predisposing factor for human diseases (cancer or allergy).
4. The content of the raw materials used in the finished product does not match the product labeling. The composition and content of raw materials are important reference information to guide consumers to purchase. The national mandatory standard GB5296.4-1998 "Description of the use of textiles and clothing instructions for consumer goods" stipulates that textiles and clothing labels shall comply with the requirements and principles of marking textile fiber content specified in FZ/T01053-1998 "Textile Fiber Content Marking". Content tolerance.
