Status of functional textile safety problems

Since the 90s of last century, the development of functional textiles has been on the rise in the Chinese market, and has formed a functional textile industry pattern with a certain scale, relatively complete varieties, perfect functions and relatively stable development. At present, the biggest problem in the development of functional textiles is the lack of functional evaluation methods and evaluation standards. In recent years, although scientific research institutes, standardization organizations and related enterprises have carried out research work in this field, and achieved some achievements, some functional evaluation methods have been standardized. But in general, most functional textiles are still not recognized by authoritative inspection institutions, making the consumption of functional textiles too blind and effective supervision, which is obviously unfavorable for the healthy development of functional textile industry.
Another overlooked problem is the safety of functional textiles. As we all know, some special functions of functional textiles are mainly achieved by adding some special functional chemicals in fiber materials or after finishing products. However, a considerable part of these chemicals used in functional textiles have not been evaluated strictly, especially for long-term risk assessment. In fact, some functional additives, which have been widely used previously, have been found to be harmful to the human body or the environment, and have been banned. Therefore, from the perspective of consumer safety and environmental protection, it is extremely important to establish an effective safety assessment specification, which can provide guarantee for the healthy development of functional textiles.
Take flame retardant textiles for example. According to statistics, over 20% of the world's fire accidents are caused or expanded by the burning of textiles, especially in residential fires. The proportion of fire accidents caused by the fire or spread of textiles is larger. According to the statistics of the Fire Department of the Ministry of public security, there were 132 thousand fires in the country in 2010, with 1108 deaths, 573 injured people and 1 billion 770 million yuan of direct property loss. Especially in 2010, the "11.15" Jiaozhou road fire accident in Shanghai caused 58 deaths and nearly a hundred people were seriously injured, making the flame-retardant textiles again become a hot topic of public concern. Therefore, the function of flame retardancy has become one of the necessary functions of interior decoration and public place textiles. The flame retardant textile finishing can be obtained by using the general function of flame retardant, with flame retardant effect of boron and aluminum elements: A III, inorganic compounds as flame retardants for non durable cotton fabric; IV group B and group V B titanium and zirconium niobium and its compounds for wool fabric; the main elements of V the A family of nitrogen and phosphorus, antimony and VII A family is halogen flame retardant in nitrogen and phosphorus, which is used for cellulose fiber, halogens and antimony used in synthetic fibre and the durability of flame retardant. The earliest by the disabled is three flame retardant (N-heterocyclic propyl) phosphorylation, itself highly toxic, LD50=37 ~ 46mg/kg, and carcinogenicity. In 1997, the American Cancer Institute found that three (2,3- dibrocyl) phosphate was banned from carcinogenicity and highly toxic, and its LD50=50mg/kg. The European Union's ban on flame retardants is based on the European Union dangerous goods and related amendments, including 79/663/EEC, 83/264/EEC and 2003/11/EC3 regulations. All these are flame retardants for textiles directly related to human body. But the harm of flame retardant is not so clear, such as the four series of flame retardant tetrabromobisphenol A, in April 2008 the National Institutes of Health published a report about bisphenol A is harmful to human health report, the Canadian Ministry of health and the Ministry of environmental protection issued a statement to take control measures against bisphenol A; but in June 2008 the European Commission issued the risk assessment report of bisphenol A, the statement of consumers can safely use packaging containing bisphenol A container in direct contact with food. It can be seen that the safety of functional finishing agents is sometimes implied, not very intuitive.
Take anti radiation textiles for example. In 2011 the Japanese "3.11" earthquake caused the Fukushima Daiichi nuclear power plant accident will be "radiation" as a hot topic, a time has become a popular white color, pregnant woman "radiation-proof clothes" hot. In fact, with the rapid development of radio, television, communication and electric power, the whole biological community has been immersed in electromagnetic radiation. Electromagnetic radiation has become the fourth source of pollution after air pollution, water pollution and noise pollution. The human body by electromagnetic radiation, not only the surface of the skin and deep tissue heating, cooling difficulties, is conducive to the growth of cancer cells, so long-term exposure to electromagnetic radiation in the environment, the body will be affected by different degree of damage, especially to the body in the sensitive period and low resistance times harm pregnant women. Therefore, radiation textiles has become the necessary protection tools in women of childbearing age, but the domestic enterprise specializing in the production of pregnant women with less than one hundred, and mainly to small and medium enterprises, and even many of them are family workshops, the technical content is low, the product quality is difficult to guarantee, causing the market blindly exaggerate the efficacy of products in order to deceive consumers phenomenon have occurred. As far as radiation proof pregnant women's clothing is concerned, it is difficult to determine whether it can really play the role of radiation prevention, or even do other harm to the body. Some production enterprises use the materials containing heavy metals such as mercury, lead, nickel and chromium to make the radiation proof maternity dress. It also plays the role of radiation protection, but the harm of heavy metals to pregnant women and fetus is immeasurable. Can be seen in the development process of functional textiles
