Flame retardant fabrics Because almost all textile materials will burn when they encounter a fire source,

It is therefore necessary to define and describe the combustion of these materials. Keene textiles refer to such a type of textiles,

They ignite when they encounter an ignition source, and continue to burn under normal conditions until they are exhausted.

Fire-resistant textiles may or may not be ignited when they encounter a fire source, but if they do, when the fire source is removed,

It will extinguish itself after a short period of burning or smoldering.


In order to improve the safety of textiles, the decomposition process of textiles during combustion must be stopped, otherwise the fabrics will be completely destroyed.


Flame retardant grade flame retardants can interfere or alter the decomposition process of fabrics in several ways:

(1) The flame retardant melts at relatively low temperatures and then re-solidifies into a foam, thus creating a barrier that prevents heat transfer from the flame to the fabric.

(2) When the flame retardant fabric agent is heated, it will decompose into acid or alkali, and these acids or alkalis can catalyze the decomposition of the fabric at a temperature lower than the temperature that can generate volatile combustibles.

(3) The flame retardant will decompose or sublime when heated, and at the same time release a large amount of incombustible gas, which prevents the supply of oxygen to the flame.

(4) The flame retardant can react with the chemical substances in the flame to terminate the combustion reaction.


Most textile flame retardants alter or interfere with the normal thermal decomposition process of polymers (fabrics).

The flame retardant in the solid matrix (here is the fabric) can reduce the decomposition temperature of the fiber, change the generation and amount of the generated flammable gas,


They can also function in the gaseous state. For example, compounds containing phosphorus can be converted into acidic species,


It catalyzes the thermal decomposition of the polymer. When the polymer decomposes, the UV-blocking fabric flame retardant containing bromine or chlorine will also decompose into flammable gas,

Halogens are also released with flammable gases, which in their gaseous state prevent combustion. In order for chemical flame retardants to be effective, it is important that when the polymer decomposes,


Flame retardant multifunctional composite cloth flame retardant can play a role. There are currently three methods of altering the flammability of fabrics.

(1) Usually chemical finishing applies the flame retardant to the surface of the fabric.

(2) Add the flame retardant to the polymer in a certain synthesis process before spinning

(3) Develop fibers with their own flame-retardant fabric properties, and then make fabrics.
