Flame retardants for Other Fibres

The most successful approach for flame-retarding acrylic fibres is to copolymerise halogen-containing monomers into the fibre.
Polypropylene fibres can be flame retarded with bromine- and phosphorous- containing additives to the polymer melt. However, very high add-ons are necessary and fibre properties are adversely affected. When polypropylene is used in carpets, flame retardancy can be achieved by incorporating halogen-containing compounds and antimony trioxide into the latex backing.
Although m-aramid fibres (for example Nomex) have an inherent flame retardancy, caused by their high decomposition temperature, this retardancy can be enhanced by the use of certain halogen/phosphorous compounds during exhaust dyeing. Along with Nomex, other inherently flame-resistant fibres such as Kevlar, PBI, Basofil or Kynol and flame-retardant modified polyester and regenerated cellulose find uses in protective clothing and other textiles that require flame resistance.
Inorganic fibres such as ceramic and glass may be incorporated into, or used entirely for, textile products where appropriate to take advantage of their inherent non-flammability .product samples are curtains, textile tape stripes and fire blockers in airplane, automotive and military textile.
