Environmental friendly flame retardants for textiles had less harm to human body and environment

which was in line with the concept of green development. Traditional flame retardants such as halogen flame retardants had higher flame retardant efficiency

but they could release a lot of toxic and corrosive gases when used. Nitrogen

phosphorus

boron

silicon and other flame retardants were not ideal when they were used alone

and the cost was high. Therefore

they need to be combined with other flame retardants to achieve the flame retardant effect. The compound synergistic technology avoided the defect of using a single flame retardant

integrates the advantages of various flame retardants

reduces the addition of flame retardants

and improves the flame retardant performance of textiles. In order to further improve the flame retardancy of textiles

we can optimize the flame retardant finishing methods of textiles. Various surface treatment technologies

such as sol-gel method

nanoparticle adsorption

layer by layer self-assembly

plasma treatment

biological macromolecule deposition and graft copolymerization modification

are introduced in this paper. The synergistic technology of flame retardant was applied to various surface treatment technologies of flame retardant finishing

which improved the flame retardancy and washing resistance of textiles

and maintained the original properties of textiles. In this paper

the research on synergistic technology of flame retardant compounding was described in detail

the problems existing in the current flame retardant industry were briefly described

and the corresponding solutions were put forward. Finally

it was pointed out that bio based flame retardant and multifunctional flame retardant textiles are the development trend of textiles in the future.
