ABSTRACT:
Flame retardant fabrics are used in the world of protection and safety of persons and things which will ensure safety to human things, thereby ensuring general safety. Flame retardant fabrics can be obtained by application of finish by use of flame resistant fibres ,by use of heat resistance fibres .Demands on newly development flame retardant fabric are that it should be fire and heat protective ,should be antistatic, breathable, absorptive, non irritating ,durable should have good colour fastness, adequate strength, excellent peeling resistence and should be easy to wash. The current trend and the new generation of flame retardant fabrics aims to find solutions to specific risks with more precision and efficiency by combining different …show more content…

• Flame retardant chemicals are also classified as non-durable and durable-inorganic salts, mixture of borax and boric acid, ammonium sulfamate, ammonium bromide, ammonium salt of strong acids like diammonium phosphate are examples of non durable flame retardant chemicals. Hydroxymethyle,phophonium chloride,a combination of N-methylol dimethyle phosphonopropionamide with trymethylol melamine and phosphoric acid etc are the examples of durable flame retardants.
Bromine containing derivatives of phosphonitrile chloride is a possible durable flame retardants for cotton fabrics.
A combination of two existing flame retardants , THPC and the bromoform triallylphosphate polymer, produces a flame retardant finish for cotton which is superior to that of either finish alone …show more content…

RECENT DEVELOPMENT IN FLAME RETARDANT :

Recently , biomacromolecules such as proteins and deoxyribonucleic acid have shown unexpected flame retardant features when deposited on cellulosic or synthetic substrates , like cotton , polyester or cotton polyester blends . The use of some of these biomacromolecules as flame retardants , is a significant advantage , since they can be considered as water or by – products from the cheese and milk industry .
These biomacromolecules can be applied to fabrics using an exhaustion process or a layer by layer method, starting aqueous solution and hence exploiting a green technology. The mechanism through these biomacromolecules are able to confer flame retardancy to fabrics, is still under investigation.
Caseins and hydrophobins, which contain phosphate groups and disulphide units have been assessed as effective flame retardant systems for cellulosic substrates, since these components are capable of influencing the cellulose pyrolisis towards the formation of char.
Whey protines have shown their suitability to form protective proteins on cotton which exhibit great water vapour adsorption that may justify the achieved flame resistance of the treated
