The Influence Of Melamine On Textile And Clothing

Recently, the contamination of Sanlu milk powder has shocked people in China, especially those with babies. While they are sorry for the children who are unfortunately affected by this incident, they are also worried about whether their babies are affected to a certain extent. This incident means that infants and young children who have consumed Sanlu milk powder containing a large amount of melamine have produced kidney stones. In Baidu, the explanation for melamine is this: melamine is pure white monoclinic crystal, tasteless, is a widely used basic organic chemical intermediate product, the main purpose is to produce melamine formaldehyde resin (MF) raw materials. Melamine can also be used as flame retardant, water reducer, formaldehyde cleaner, etc. The hardness of the resin is higher than that of urea formaldehyde resin. It is non flammable, water resistant, heat resistant, aging resistant, arc resistant, chemical resistant, good insulation property, gloss and mechanical strength. It is widely used in wood, plastics, coatings, paper making, textile, leather, electrical, medical and other industries. Its main uses are as follows: (1) decorative panels: it can be made of fire resistant, aseismic and heat-resistant laminates, bright, strong, heat-resistant decorative panels, as a panel for aircraft, ships and furniture, and fireproof, aseismic and heat-resistant housing decoration materials. (2) coating: after the etherification of butanol and methanol, it is used as the adhesive for high grade thermosetting coatings and solid powder coatings, and can be used for making metallic coatings and high-grade amino resin decorative paint for vehicles and electrical appliances. (3) moulding powder: it can be made into melamine plastic through mixing and granulation processes. It can be kept in good condition. It can maintain good electrical performance when wet. It can be made into white, anti knock daily utensils, sanitary ware and imitation porcelain tableware, and advanced insulating materials such as electrical equipment. (4) paper: after etherification with ethyl ether, it can be used as paper treatment agent to produce high-grade paper such as wrinkle resistant, shrinkage resistant, non rotting banknotes and military maps. (5) melamine formaldehyde resin mixed with other raw materials can also produce fabric finishing agents, leather tanning agents, glazing agents and water repellents, rubber adhesives, combustion improvers, high efficiency cement water reducing agents, steel desalting agents, etc. It can be seen that these chemicals exist not only in food, but also in the field of textile and clothing. Some infant clothing manufacturers add formaldehyde dye auxiliaries and resin finishing agents in the process of fabric production. The purpose is to make the clothes wrinkle free, not shrink and fade. If children wear such clothes, formaldehyde will release slowly, and the long-term exposure to formaldehyde will cause rashes, which will have a serious impact on the growth and development of infants, and can lead to cancer. It is worth gratifying to the parents that our country's first national standard for the safety of infant clothing and clothing will be put into effect next month. The new standard is aimed at the characteristics of infants' love and clothing and clothing. The technical requirements such as the size of the collar, the unfastener of the zipper, the length and strength of the rope and the residue of heavy metals in the clothing are formulated. The standard clearly stipulates that the formaldehyde content of infant clothing should not exceed 20 mg per kilogram, and the arsenic content should not exceed 0.2 mg per kilogram. The standard specifies that infant clothing must be marked "not dry cleaned" on the product label. Because dry cleaners may contain substances that irritation to infants and young children. Here, I want to remind you of the following points: first, it is best to buy brand products, these products will be strictly checked and guaranteed; two, do not buy too bright colors and printed infant clothing, so as to avoid containing harmful substances such as decomposable aromatic amines. Three, it is best not to choose specially dressed clothes, such as ironing and soft finishing, because these clothes are likely to have relatively high formaldehyde content. Four, formaldehyde is easy to dissolve in water. The clothes purchased by infants can be reduced after washing. So the new clothes should be washed first and then placed for one or two weeks. Five, melamine formaldehyde resin has more applications in leather products, and there is also a phenomenon of excessive formaldehyde in fur coat. So try not to buy Leather clothing or clothes with leather pieces to the children, and do not let children play with leather items, such as wallet, leather key buckle, so that children do not bite, but affect the health of children.
