Infant textile quality requirements introduction
Infants and children are the flowers and hopes of the motherland, so during their growth period, the quality and safety of related products needs to be paid special attention. The recent hot issue about melamine was first discovered from infant milk powder, and people will naturally think about whether there are problems with clothing that is also closely related to the growth of infants and young children. With the continuous improvement of living standards, people's requirements for clothing products are not only satisfied with the category of firmness and durability in the past, but more and more attention has been paid to the characteristics of wearing comfort and green environmental protection. Compared with adults, infants and young children should have stricter requirements for clothing, especially in terms of safety and hygiene, due to their particularity. 1. China's infant and children's clothing related quality requirements At present, the standards related to infant and children's clothing products mainly include: national mandatory standard GB18401-2003 'National Textile Safety Technology and Specification' and GB5296.4-1998 'Consumer Product Use' Instructions for use of textiles and clothing'; product standards (such as FZ/T81003-2003 'Children's Clothing, School Uniforms', FZ/T 73007-2002 'Knitted Sportswear', FZ/T 73008-2002 'Knitted T-shirts', FZ/T 73008-2002 'Knitted T-shirts', FZ /T 73021-2004 'Knitted School Uniforms', FZ/T 81004-2003 'Dresses and Skirt Covers' and FZ/T 73025-2006 'Knitted Clothing for Infants and Young Children', etc. The main testing items involved are: formaldehyde content, decomposable Aromatic amines, pH value, peculiar smell, color fastness to water, color fastness to rubbing, color fastness to perspiration, color fastness to saliva, labeling, fiber content and physical properties testing of related products, etc. 2. At present, Chinese infants and young children The current situation of clothing-related quality Before and after Children's Day in 2008, the local quality inspection and industrial departments of Shanghai, Guangzhou, Zhejiang, Shandong and other provinces and cities, as well as the State Administration of Quality Supervision, conducted random inspections on the product quality of infant clothing retailed in the market. Action. Judging from the information released by the quality supervision departments of governments at all levels, although the qualified rate of product sampling inspection varies from place to place, most of the product quality problems are concentrated in fiber content, pH value, azo dyes, clothing instructions, formaldehyde Six aspects of release content and color fastness. 1. Many companies with fiber content have insufficient understanding of standards and product quality, or do not have testing methods and are unwilling to go to inspection agencies for testing, or are driven by interests, resulting in wrong or random labels The phenomenon of ingredient content is not uncommon. The actual cotton content of some products is far less than the nominal value, and some deliberately increase the high-grade fiber content, and even the label is completely unrealistic. Obviously, the bigger consideration here is the integrity of the enterprise. 2. When the pH value of human skin is weakly acidic, it can prevent the invasion of germs, so the pH value (acidity and alkalinity) of textiles is between slightly acidic and neutral, which is conducive to the protection of the human body. If the pH value in the textile is too high or too low, Both will destroy the balance and resistance of the skin, and are vulnerable to the invasion of germs, and the delicate skin of infants and young children is more vulnerable. According to the mandatory standard GB 18401-2003, the pH value of infant clothing and textiles that directly contact the skin is limited to 4.0 to 7.5 , but the random inspection found that the pH value of some related products was as high as 9.3. The main reasons for the failure are that the clothing manufacturers have weak awareness of safety performance and quality in the selection of raw materials, and the dyeing and finishing processes of the manufacturers are not suitable for pure cotton products and high-proportion cotton blended products. The pH is not strictly controlled, and the neutralization is not timely or sufficient after adding alkali in the production, or the cleaning is not thorough. Fang Fragrance amine compounds, through a series of activation effects, will become the inducement of human disease, and the harm to the body is very serious. The reason is that in order to pursue the beauty of patterns and colors, fabric manufacturers have intentionally or unintentionally added azo dyes containing decomposable aromatic amines in production, while most garment manufacturers have no testing methods themselves, and they do not entrust testing when purchasing goods. The department conducts this test, causing harmful products to enter the market. 4. Instructions for use of clothing GB 5296.4-1998 'Instructions for the use of textiles and clothing' The mandatory standard has been promulgated and implemented for many years. The standard clearly stipulates that textile products must be marked with the following content: the name and address of the product manufacturer; product name; product name Model and specification; composition and content of raw materials; washing method; product implementation standard; product quality grade; product quality inspection certificate, etc.
