Abstract

Previous research work in our laboratory has indicated that the efficiency of certain flame-retardant fibres can be further enhanced if certain interactive intumescents are dispersed on their surfaces. In our previously reported work we have successfully observed interactions between certain commercially available flame-retardant cellulosic and regenerated cellulose (viscose) fibres and two melamine and phosphoric acid-based intumescent systems. In the present work we have explored the use of other intumescent systems-melamine cyanurate, melamine borate, melamine oxalate, melamine pyrophosphate and an inorganic silicate-based intumescent, Cylatherm. Two non-cellulosic fibres-the novoloid (Kynol) and melamine-formaldehyde (Basofil) were also explored in combination with different intumescent systems. These systems were studied by thermal analytical techniques to observe any possible interaction between FR fibre and intumescent components. Of these intumescents, only melamine borate and melamine pyrophosphate showed interactions with flame retardant cellulosic fibres and both Kynol and Basofil indicated char interactive tendencies with some of the phosphorus-containing intumescents.
