Analysis Of Infant Clothing Safety And Health Performance Testing Items

Recommended standard of textile industry drafted by seven units such as Shanghai Clothing Research Institute. Baby "Clothing" was released on 23 April 2008 by the national development and Reform Commission of People's Republic of China, and was implemented nationwide since October 1, 2008. This standard is specially formulated for infants and young children's clothing products. It is suitable for children's clothing products that are mainly used in textile and woven fabrics for 24 months or less. Since the implementation of the standards, it has played a positive role in guiding the production enterprises to strengthen the technical quality management, ensure the products meet the design requirements, achieve the quality standard of the process and the related safety and health performance requirements. At the same time, it also provides a clear basis for product quality inspection for inspection agencies at all levels, and helps consumers understand and understand the importance of safety and health performance testing items for clothing products.

It can be said that setting relevant safety and health performance testing items is the highlight of this standard. With the introduction of the concept of "eco textiles and clothing" and the popularization and application of Oeko-TexStandard100 standard in twenty-first Century, the safety and health problems of textiles and clothing have attracted more and more attention. "Wear out safety" and "wear out health" have become an important concept of clothing consumption worldwide. Green products, which do not contain toxic and harmful substances and meet the requirements of environmental protection, are becoming increasingly popular among consumers. It is commendable that the standards of infant clothing should be included in the safety and health performance testing items, and some of the physical and chemical performance indicators should be enforced as judged whether the products are qualified or not. Obviously, it has caught up with the development level of judging the quality of textile and apparel products in the advanced countries and regions.

Infants and young children are a special group. Their body organs (including skin) are still in the growth stage, and their functions are not perfect, delicate, and their self-protection consciousness and ability have not been formed. They are vulnerable to various injuries in daily life, so they have become the objects of concern and protection. Clothing is a relatively large daily necessities associated with the human body, and is relatively close to infants and young children. Therefore, the safety and health performance of infant clothing should be given enough attention to prevent the use of objects from being harmful and harmful.

The standards for safety and health performance listed in the "infant clothing" standard include:

Products must not be dry cleaned.

Because some commonly used dry cleaning agents are volatile chemicals, which are poorly tolerated. Baby It will cause adverse stimulation and affect its growth and development. Therefore, the standard should not adopt this method to clean the product, and explicitly request the "dry cleaning" icon or text explanation on the product to prompt consumers to pay attention.

Extractable heavy metal content

Heavy metals refer to heavy metals, including copper, lead, cobalt, chromium, cadmium, nickel, antimony, arsenic and mercury. These metals have not yet been found to have any beneficial effects on the human body. Conversely, if these heavy metals are absorbed too much by the human body, they will cause harm to the human body. Heavy metals can accumulate in living organisms. The longer the time is, the greater harm will be done to the human body. Taking lead as an example, the harm of lead is mainly harmful to human nervous system, hematopoietic system and kidney. Also, it should be pointed out that Mercury is harmful to the function of human brain cells. The main cause of heavy metal composition in textiles and clothing is the absorption and accumulation of natural fiber plants from air, water and soil inlay during the growth process, as well as the absorption and residue of fabrics in some printing and dyeing processes and finishing processes, and some clothing accessories, such as zippers and buttons, also contain heavy metals released. Because of the close contact, extractable heavy metals in fabrics and clothing are easily absorbed by human body, especially infants and young children. The accumulation of heavy metals into the body will cause irreversible damage to the bones, liver, kidneys, heart and brain, and pose a great threat to human health. Therefore, the standard specifies the amount of heavy metals extracted from mercury, cadmium, lead, arsenic and copper to ensure the safety of users.

Formaldehyde content

Formaldehyde, also known as formalin, is used in medicine as a liquid form to preserve human or organ specimens. It can be used as a detergent in industry, raw materials and preservatives for plastics production. Formaldehyde in textile and garment industry mainly appears in dyeing auxiliaries and resin finishing agents. It is used for coloring and fixing fibers and fabric products, and enhances the effect of crease prevention and shrinkproof. Some of the garments are ironing and finishing with formaldehyde containing additives. Medical experts believe that Faure Marin is a chronic poisoning drug, containing Faure Marin's textile and clothing will gradually release free formaldehyde in the process of wearing, through the respiratory tract and skin contact caused by human respiratory tract and skin inflammation, but also to stimulate the eyes. Long term exposure to low-dose formalin can cause chronic respiratory diseases, menstrual disorders, pregnancy syndrome, resulting in neonatal physical deterioration, chromosomal abnormalities, and even nasopharyngeal carcinoma. High concentrations of Faure Marin are toxic to the nervous system, the immune system and the liver. The harm of formalin into the human body is also manifested in its ability to coagulate proteins and cause cancer. Therefore, the regulations and standards of some countries strictly limit the formaldehyde content of textiles and garments. Combined with the characteristics of infants and young children, the "infant clothing standard" stipulates that the formaldehyde content of products must be less than or equal to 20mg/kg.

PH value

The pH value is an indicator of the intensity of a substance's acidity and alkalinity by chemical analysis and expressed in numerical terms. The number is from 0 to 14, with 7 as the center value, which is neutral. The closer to 14, the greater the 7, the stronger the alkalinity is, the closer to 0 is less than 7. Between 4 and 7, it is called weakly acidic, and between 7 and 9 is called weak alkaline. Generally speaking, the surface of human skin is slightly acidic, which can inhibit the invasion and anti allergy of bacteria. Since the raw materials used in textiles are often acidic or alkaline chemicals used in weaving, printing and dyeing, finishing may cause changes in the slightly acidic state of the skin surface and affect human health. Therefore, some countries in the textile and clothing quality inspection, increased the pH value of the detection project, mainly to identify its fitness with the human skin, whether it can play a role in inhibiting bacteria, cleaning and inhibition of allergy. Generally speaking, when the pH value of textiles and clothing is between weak acid and weak alkaline, it can achieve good effects of protecting human body from bacteria. Combined with the characteristics of infants and young children, the "infant clothing" standard stipulates that the pH value of products must be between 4 and 7.5.

Decomposition of aromatic amines (azo) dyestuff

This type of dye is proved to be harmful by experiments, and carcinogens can be released during use. The textile and clothing dyed with this dye will release and release a certain amount of toxic substances. Through long-term direct contact with human body, the toxic substances will be absorbed by the skin, affect the tissues and organs in vivo, change the original DNA structure, and eventually induce lesions and cause cancer, and endanger human health. In July 1994, Germany banned the production, use and sale of azo dyes containing such carcinogenic aromatic amine substances for the first time in the form of government legislation. Subsequently, Holland and Austria also actively followed suit. At present, the banned azo dyes have become one of the important control items in the safety and health quality of the international textile and garment trade. According to the European eco textile standard, there are 23 kinds of azo dyes that contain carcinogenic aromatic amines in the course of use. In the course of trade, if one of the fabrics or garments is detected, the product is judged to be unqualified and rejected. The "infant clothing" standard is also listed as prohibited. The names of these azo dyes that can decompose aromatic amines can be seen in the appendix of the mandatory standard of GB18401-2003 national basic safety technical specification for textiles. {page_break}

Peculiar smell

Textile and clothing materials are not clean, contain toxic substances, or are contaminated by certain toxic substances during production, transportation and storage because of improper methods. They will emit some unusual odors, such as mildew, high boiling point gasoline, kerosene, fishy smell and pungent aromatic hydrocarbons, perfume and so on. These odors have different degrees of damage to human health. In addition, feather and down products made from poultry feathers and fluff are used. If the cleaning methods are not in place, washing and washing for a long time may produce rotten odors or odors, which will affect the wearing and hygiene. Therefore, the "infant clothing standard" stipulates that products may not smell bad.

Through further understanding and learning of the standards of infant clothing, people will be able to recognize the importance of inspection and control of clothing products to enhance safety and health performance. In particular, infant clothing products, in terms of the inspection and judgement of these items, is more careless. The promotion and application of infant clothing standards in the textile and garment industry will certainly help to strengthen source control. We urge the producers to further implement the measures, constantly improve the safety and health performance of products, improve the internal quality and credibility of products, and consumers will further improve the ability to identify the quality of products, and better protect themselves. At the same time, by increasing the supervision of the market, there will be fewer and fewer opportunities for those products that are not up to standard.
