Non-woven fabric flame retardant treatment

Flame retardancy can be achieved in two ways: additive (mechanically blended flame retardant chemistry and polymer before extrusion) and partial (coated fiber or fabric with flame retardant chemistry). Additive types are useful with thermoplastics, while topical treatments can be used with thermoplastics, thermosetting plastics and natural fibers.

Inherently flame-retardant fibers are materials that have flame retardancy built into their chemical structure. The actual structure of the fiber itself is non-flammable. It is inherently flame-retardant fiber, and the protection is built into the fiber itself and cannot be abraded or washed out. The other main category is flame retardant treated (FRT) fabrics. These materials are made flame retardant by the application of flame retardant chemicals. Chemical additives on the fiber or treatment on the fabric are used to provide a certain degree of flame retardancy. In the event of a fire, chemical-related fabrics rely on chemical reactions to extinguish the flame. This reaction is triggered by the heat of the fire and the amount of time the fabric is exposed to the fire.

  The inherent flame-retardant (FR) characteristics of flame-retardant fabrics, on the other hand, cannot be eliminated or worn out. This means that the flame-retardant properties of the inner fiber garment cannot be compromised. This is vital for the wearer to know that flame retardant protection is always there.

   The other is a strong flame retardant, which is a chemical substance that interferes with one or several steps in the combustion process. This is done in four different modes of action:

"The reaction is carried out in the gas phase."

  The reaction is in the condensed phase.

   cooling effect.

   dilution effect.

   It is very difficult to determine whether the protective device is damaged with the F There are some ways to test it. Unfortunately, all of these test methods are destructive-there is really no way to test clothing to determine its current level of flame retardancy or arc protection value without destroying the flame or arc flash test of the clothing.
