Brief introduction of flame retardant chemical fiber
In recent years, the research, development and use of flame retardant fiber gradually increased, and there is a great progress. With the ACCELERATION OF urban modernization, the development OF tourism, transportation industry, and the increase of demand for export, there is a huge potential market for flame retardant fiber series products. According to the survey, the consumption of flame retardant products is mainly distributed in iron and steel casting industry, fire service industry and chemical manufacturing industry. Government units are mainly hospitals, the army and forest fire service teams. In addition to clothing, automobile, train, aircraft with flame retardant textile products prospect is also potential infinite. In addition, if coupled with the film, theater, auditorium seats with cloth, it is considerable. Polyester (polyethylene terephthalate, PET) has many advantages, its textiles have been widely used, has become the most widely used, the largest consumption of varieties, so its flame retardant has attracted extensive attention worldwide. In addition, it is reported that the world production of flame retardant polyester fiber has accounted for 10-15% of the total production of polyester fiber. Foreign studies on flame retardant copolyesters of phosphorous are extensive and thorough, and there are many literatures about them. The industrialized flame retardant polyester fiber is mainly modified by copolymerization. Phosphorous flame retardant system in polyester not only reduces the heat release rate of the material through the mechanism of carbon formation and mass retention in solid phase and partially flame retardant in gas phase. It has good flame retardant, and reduces the release of corrosion or toxic gases and smoke, so it has the characteristics of environmental friendliness.
At present, flame retardant materials are going hot, especially in North America, Central America and Europe, flame retardant technology has a good momentum of development, and the research and innovation of flame retardant in Asia is also progressing day by day. California is a hot spot for the development of flame retardant materials technology. In 2005, some laws and regulations (such as the very strict mattress regulations) and the federal standard 16CFR1633 were completed and passed. In addition, the North American Free Trade Agreement (NAFTA), the California Consumer Product Safety Commission (CPSC) and the European Union on Dangerous goods restrictions (POHS) rules and so on. All these indicate that the new laws and regulations at the state level, the union level and the European Union, as well as the rise of modern technology, have put forward unprecedented new requirements and challenges to this industry. At the same time, the provisions of these laws and regulations have put forward higher requirements and standards for people's safety and health. Thus promote the research and development of textile flame retardants and flame retardants. America, Europe, Japan and the relevant companies in our country have carried out a large number of experiments and research. The flame retardant properties of fiber products are greatly improved and meet the requirements of various laws and regulations.
