The manufacturability of non-woven fabrics, non-woven fabrics are soft in texture and comfortable to use. In addition to using better production technology and choosing better raw materials, it also has its own manufacturability. What are the general reasons that affect the flame retardancy of non-woven fabrics?
The reasons that affect the flame retardancy of non-woven fabrics are as follows:
1. 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.
2. 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. Phosphorus is combined with oxygen in the air under high heat to reduce the low oxygen content. The characteristics achieve good flame retardant effect-fruit.
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. However, 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.
The main reasons that affect the flame retardancy of non-woven fabrics are the reasons that we shared with you above. If there is a problem, we all need to deal with it in time.
