Heat and flame protection of conventional textile fibres

4 Heat and flame protection of conventional textile fibres 

These fibres are primarily listed in Table 8.2 and as stated above, they are not often used in technical textiles requiring the highest levels of protection. The fibres within this group may be broadly subdivided into those fibres requiring chemical after-treatment, those requiring additives during production and those in which a basic polymeric modification is introduced. These fibres together also find use outside the area of technical textiles and so the focus here will be away from their consumer textile applications. 

The chemistry of these processes, mainly for natural fibres and their blends, has been well documented over the last 50 years with a number of classic reviews as well as more recent ones.  

These factors usually mean that the majority of acceptable flame retardant treatments involve one of the following chemical processes  

durable finishes based on N-methylol dialkylphosphonopropionamides and typified by the Pyrovatex (formerly Ciba, now Huntsman) chemistry range of products and the many equivalents on the market
