The combustion of flame-retardant fabric fibers is essentially a process in which the fibers are heated to decompose flammable substances and react violently with oxygen. In this continuous cycle of reaction processes, flammable substances, oxygen and external heat are the three basic components of combustion. Elements, flame retardancy is to try to reduce the production or existence of flammable substances. There are two main types of flame retardant technology. One is to accelerate the dehydration and carbonization of the fiber to reduce flammable substances to achieve flame retardancy; the other is to change the inner structure of the fiber through a chemical process to reduce flammable components to achieve the purpose of flame retardancy.
The flame-retardant fiber greatly slows down the burning speed of the fiber, extinguishes itself immediately after the fire source is removed, and the burning part is quickly carbonized without melting, dripping or holes, giving people time to evacuate the burning Take off the burning clothes on site to reduce or avoid burns and scalds for the purpose of protection. Flame retardant technology, a form of in-depth protection, prevents fire from spreading and disappears invisible. This is of great significance in reducing fire accidents and avoiding burns and damage, and is widely adopted by industrialized countries.
The quality of Oxford cloth can be judged by measuring the oxygen index (also called limiting oxygen index) of the sample. Fabrics require oxygen to burn. The oxygen index LOI is an expression of the amount of oxygen required for sample combustion. Therefore, the flame retardant performance of fabrics can be determined by measuring the oxygen index. The higher the oxygen index, the higher the oxygen concentration required to maintain combustion, which means the more difficult it is to burn. This index can be expressed by the smaller volume percentage of oxygen required for the sample to maintain candle-like combustion in a mixture of nitrogen and oxygen. Theoretically, as long as the oxygen index of textile materials is greater than 21% (the volume concentration of oxygen in natural air), it will be self-extinguishing in the air. According to the size of the oxygen index, textiles are usually divided into flammable (LOI35%) Four levels. In fact, almost all conventional textile materials (fibers) fall into the flammable or combustible range.
