What Kinds of Flame Retardant Fabrics are There?

What are the main flame retardant fibers that make up the flame retardant fabric? There are many kinds of flame retardant fiber. It has been proved by many researches that the fabric made of flame retardant fiber has some advantages of flame retardant. Next we will introduce different types of flame retardant fiber and its application.

Flame retardant fiber in flame retardant fabric - flame retardant viscose fiber

The methods of flame retardant modification of viscose fibers mainly include grafting, blending and copolymerization.

Flame retardant viscose fibers do not burn when exposed to fire, forming a dense carbonized layer that protects the fibers from oxygen and then regenerates. Because cellulose fiber itself does not melt, flame-retardant viscose fiber also has no drop effect.

Flame retardant viscose fibers can be woven into a comfortable fabric for use in underwear, pajamas and bedding. It can also be blended with various flame retardant fibers, such as nitrile chlorlon, chlorlon, flame retardant polyester, etc. This flame retardant fabric can be used in interior decoration and auxiliary materials.

In the 1960s, dupont produced Nomex with a limit oxygen index of about 32, which has permanent flame retardancy and does not melt at high temperatures, and has excellent thermal stability. The flame-retardant aramid fabric made in China can achieve the same flame retardant performance, and also have excellent chemical resistance, better mechanical properties, soft feel, spinnability and radiation resistance. It has a great application in flame retardant work clothes and fire fighting clothes.

Flame retardant fiber in flame retardant fabric - polysulfonamide (PSA)

Aromatic sulfonamide belongs to the series of para-aramid, with a limit oxygen index of 33, difficult to ignite, with self-extinguishing, rarely having smouldering or afterburning phenomenon. The flame-retardant requirements of different thermal protective clothing can be met by the flame-retardant indicators of flame-retardant duration and damage length of aromatic sulfonamide.

Flame retardant polyester fiber in flame retardant fabric

The main methods of weaving flame retardant polyester fibers include copolymerization flame retardant modification, blending flame retardant modification and flame retardant finishing. Fiber bath fire does not burn, but will still melt and appear droplets.

Flame retardant fiber in flame retardant fabric -FBI fiber

Polybenzimidazole (PBI company) fiber, not the thermoplastic flame-retardant fibers in the air, but it doesn't burn, limit oxygen index up to 40, a long time exposure in 600 ℃ flame, only 10% contraction, the fabric is still intact, soft. It has good chemical resistance, moisture absorbency and handle, good textile processing performance, so it has a good use in fire clothing.
