The Summary of Flame Retardant Textiles

With the rapid increase of all kinds of civil and industrial textiles consumption, especially all kinds of interior decoration, the cabin decorative fabric (curtains, curtain, carpet, furniture, wall cloth cloth) and bedding growing demand, textile caused the fire will continue to increase. In twentieth Century 60 years, Japan, Europe and other developed countries on the flame-retardant finishing of textiles and puts forward the requirements, and make each kind of textile flame retardant standards, from textile types and use place limit non flame retardant fabric. Such as the United States on the curtains, bed sheets, pajamas, children's clothes, automobile fabric, camping tent, toys and other textiles, formulation of the relevant combustible laws, state statute, urban doctrine and personality also set their own standards and regulations. Japan prescribed by 31m over the use of the high-rise buildings, underground street, theatre, hotel, hall, bar, kindergartens, nurseries and other public facilities of the curtain, curtain, bedding and clothing, the old and the young to use carpet must meet the provisions of the flame retardant standards. In addition, the use of aircraft, ships, vehicles of all kinds of textiles have clear flame retardant regulations in international business. The development of these flame retardant regulations.
To promote the development of flame retardant textiles. According to the provisions of the international organization for standardization, flame retardant (or antibacterial) refers to the slow, materials with the termination or prevent combustion properties. It is an inherent property of the material, can also through certain processing, give this material properties. Textile flame retardant technology is the application of the establishment in the latter theory on. Study on combustion mechanism of modern show that a closed * process of combustion and flame retardant fabric, the purpose is to break the chain reaction, namely: in the exothermic stage, the flame retardant is a strong endothermic agent; thermal degradation in the stage, flame retardant fiber thermal degradation as a catalyst to alter the way, making it less toward the combustible gas. The larger solid direction reaction; in the flame zone, flame retardant agent through the release of free radical inhibitor, capture agent cut *, is the active free radical passivation, achieve the purpose of flame retarding. Numerous studies have demonstrated that flame retardant textiles has certain superiority. Flame retardant textiles allows longer escape events (increased 10~15 times), the combustion heat released only non flame retardant fabric non flame retardant fabric 25%, but fire damage is reduced by half, combustion release of toxic gases only non flame retardant fabric 1/3 (CO value), and does not produce the intense smoke, can protect human life. Someone has done a comparison test of two decorative chair, after the flame retardant finishing a chair a set, a whole without flame retardant.
Physical contact with fire, in equal conditions, test the discovery after the flame retardant finishing coverings allow 22min escape time without flame retardant finishing a set of only 2min of the escape time. Curtains, carpets, bed sheets after the flame retardant finishing red can achieve good results. Thus, through appropriate flame retardant finishing items can make the probability of fire is greatly reduced, thereby preventing the occurrence of life-threatening situation, reduce the risk of the spread of fire, escape events can also significantly increase. Compared to the textile sales price, flame retardant used in textile cost is much lower; on the other hand, the protective effect of flame retardant on the human life and property safety is immeasurable, far more than its commercial significance.
