Introduction to flame-retardant synthetic fibers


In recent years, China's research, development, and use of flame retardant fibers have gradually increased, and significant progress has been made. With the acceleration of urban modernization construction, the development of tourism and transportation industries, and the increasing 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 the steel casting industry, fire service industry, and chemical manufacturing industry; Government units mainly include hospitals, military, and forest firefighting service teams. In addition to clothing, flame-retardant textiles for cars, trains, and airplanes also have endless potential. In addition, adding seat covers for movies, theaters, and auditoriums would be even more impressive. Polyester (polyethylene terephthalate, PET) has many advantages and is widely used in textiles. It has become the most widely used and consumed variety, thus its flame retardancy has attracted widespread attention worldwide. In addition, according to reports, the production of flame retardant polyester fibers in the world has accounted for 10-15% of the total production of polyester fibers. The research on phosphorus based flame retardant copolyesters in foreign countries is more extensive and in-depth than in China, and there are many related literature reports. The industrialized varieties of flame retardant polyester fibers abroad mainly use copolymerization flame retardant modification methods. The phosphorus based flame retardant system in polyester not only reduces the heat release rate of the material through solid-phase carbonization and mass retention mechanisms, but also partial gas-phase flame retardant mechanisms. It has good flame retardancy and reduces the release of corrosive or toxic gases and smoke, making it environmentally friendly.
Flame retardant materials are currently gaining popularity, especially in North America, Central America, and Europe where flame retardant technology is developing well. In recent times, research and innovation in flame retardants in Asia have also been advancing day by day. California, USA is a popular destination for the development of flame retardant material technology. In 2005, some laws and regulations (such as the very strict mattress regulations) and federal standard 16CFR1633 were completed and passed. In addition, there are regulations such as the North American Free Trade Agreement (NAFTA), the California Consumer Product Safety Commission (CPSC), and the European Union on Hazardous Goods Restrictions (POHS). All of these indicate that new regulations at the state, federal, and EU levels, as well as the rise of modern technology, have unprecedentedly posed new requirements and challenges to this industry. At the same time, these regulations have put forward high requirements and standards for people's safety and health. Thus promoting the research and development of flame retardant properties and flame retardants for textiles. Companies in the United States, Europe, Japan, and China have conducted extensive experiments and research. Significant progress and achievements have been made, resulting in a significant improvement in the flame retardant performance of fiber products and meeting the requirements of various regulations.
