Conclusions
The possibility of raising the oxygen index of fibres of aromatic polyamides by use of organophosphorus or chlorinated organic compounds has been examined. It has been shown that, to obtain modified fibres whose fire-protected effect is resistant to wet treatment, it is necessary to introduce glycasine additionally into the fibre.
As a result of investigating the physicomechanical properties of the original and flame-protected fibres, it has been found that the use of organophosphorus compounds for the modification of fibres from aromatic polyamides is more advisable.
