The main component of flame-retardant non-woven fabric is polyester, which belongs to chemical fiber. The flame-retardant non-woven fabric has the characteristics of high strength, good elasticity, good heat resistance, smooth surface, and good abrasion resistance. So everyone knows what is the reason for the flame-retardant non-woven fabric?
The reasons for the flame retardancy of flame-retardant non-woven fabrics are as follows:
1. If the polyester slices are modified and denatured to have a flame-retardant effect-fruit. Most of the long-acting flame-retardant fibers use modified polyester chips to produce flame-retardant polyester cotton. The main modifier is phosphorus series compounds, which use phosphorus to combine with oxygen in the air at high temperatures.
2. Conventional polyester cotton has a limiting oxygen index of 20-22, which is a kind of combustible fiber, which is easy to ignite but has a slower burning speed.
3. Another method to make polyester cotton flame-retardant is the surface treatment method. This kind of product is thought to reduce the flame retardant effect after the treatment agent is processed for many times.
4. Polyester cotton has the characteristic of shrinking when encountering high heat. When the fiber encounters a flame, it will not be easy to ignite due to shrinkage and separation from the flame, resulting in a proper flame retardant effect.
5. Polyester cotton will melt and drip when it encounters high heat. The melting and dripping phenomenon of polyester cotton after ignition can also take away part of the heat and flame, and produce appropriate flame-retardant effects.
6. Increasing the flame retardant method of polyester cotton, in addition to the use of flame-retardant modified polyester chips to produce polyester cotton, the use of a finishing agent with a higher phosphate content on the surface of the fiber can also increase the resistance of the fiber. Fuel efficiency-fruit.
7. But if the fiber is stained with oil that is easy to support combustion or use silicone oil that can set the polyester cotton, the polyester cotton will reduce the flame retardant effect. Especially-when the polyester cotton containing SILICONE oil agent encounters flame, the fiber cannot shrink and burn.
The reason for the flame retardancy of flame-retardant non-woven fabrics is mainly due to the above. Flame-retardant non-woven fabrics are flame-retardant, and their flame retardancy is very good.
