What are the characteristics and uses of flame retardant fabrics?
Flame-retardant fabrics are fabrics that have been post-processed and can have anti-static functions. There are two fundamental reasons why flame-retardant fabrics can be flame-retardant. One is to accelerate fiber dehydration and carbonization to reduce combustible substances to achieve flame retardancy, such as the ammonia treatment of the fabric and the treatment of cotton cloth; the other is to change the inner fiber of the fiber through a chemical process The structure reduces combustible components and achieves the purpose of flame retardancy.
Durable flame-retardant fabrics are made by spinning, weaving and dyeing congenital flame-retardant fibers. The fabric has the characteristics of flame retardant, abrasion resistance, temperature resistance, washing resistance, acid and alkali resistance, waterproof, anti-static, high strength and so on. Suitable for protective clothing fabrics in metallurgy, oil field, coal, chemical, electric power, fire protection and other industries.
Flame-retardant cloth refers to cloth that can be automatically extinguished within 12 seconds after being ignited by an open flame. According to the order of adding flame retardant materials, there are two types: pre-treatment flame-retardant cloth and post-treatment flame-retardant cloth.
Flame-retardant fabrics can be used in many aspects of ship frame structure and repair in the shipbuilding industry; it can also be used in petrochemical companies where heat insulation, insulation and welding of metal layouts are required, showing good protective adaptability. The fireproof blanket processed with fireproof cloth is suitable for hot construction in large shopping malls, supermarkets, hotels and other public entertainment places: such as welding, cutting, etc.; the use of this product can directly reduce spark splash and reduce flammability. , Blocking and blocking of explosive dangerous goods, and ensuring the safety of human life and the integrity of the industry.
What industries are polyester flame-retardant fabrics used in?
The flame retardancy of the fabric is often realized through the principles of gas phase flame retardant, condensed phase flame retardant and interrupted heat exchange flame retardant. It is gas phase flame retardant that inhibits the growth of the combustion reaction chain and freely exerts the function of flame retardant fabric; it retards or prevents the thermal decomposition of polymer in the solid phase and acts as a flame retardant, which is condensed phase flame retardant; part of the heat generated by the burning of polymer The flame retardant caused by taking away belongs to the flame retardant of interrupting the heat exchanger.
Due to its durable flame retardancy, polyester flame-retardant fabrics have a broad application prospect. It is understood that flame-retardant polyester has a wide range of applications. In addition to its irreplaceable role in industrial textiles, architectural interior decoration, and vehicle interior decoration, it also plays a lot of roles in the field of protective clothing. The flame retardant protective clothing has excellent washing resistance, non-toxic, tasteless and non-irritating, safe and reliable to the human body, breathable and moisture-permeable, soft to the touch, and comfortable to wear.
According to the national standards for flame-retardant protective clothing, metallurgy, forestry, chemical, petroleum, and fire protection departments should use polyester flame-retardant protective clothing.
