Flame retardants are used by adding to flammable materials such as textiles to make them hard to burn or not spread.
Flame retardant processing on textile products can minimize damage and save lives when a fire occurs.
For example, curtains, carpets, car seats, sofas, firefighting clothes, etc. are processed flame retardant.
Combustion means that flammable textile products are decomposed by the heat of the ignition source, gasified, and mixed with oxygen in the air to cause a violent oxidation reaction.
The reaction heat generated by this oxidation reaction decomposes and gasifies the subsequent fiber, and combustion is repeated.
In order to suppress combustion, it is effective to make the textile flame retardant by the method shown in the following 1 to 5 and to prevent the progress of this cycle.
1. Control of heat transfer :
Coating with inorganic compound
(borax, thermal insulation layer, etc.)
2. Gas dilution or addition of noncombustible gas :
Add noncombustible gas to mixed gas and suppress combustion
3. Control of solid phase decomposition rate :
Lower the melting point of the fiber and increase the endothermic capacity of the surface
4. Dehydration reaction :
Acceleration of carbonization by dehydration reaction
(ammonium sulfate, phosphorus compound)
5. Radical termination :
Traps radicals in combustion reactions
