effect of durable flame retardant products on knitted fabric flammability has
been studied. Firstly, the non-durable, semi-durable and durable flame
retardants were applied to the bleached knitted cotton fabrics to observe their
effects on fabric flammability and then phosphorus-based durable flame
retardant products were applied to bleached fabrics at
different
concentrations, curing temperatures and curing times alternatively to evaluate
the effect of their treatment parameters on fabric burning behaviour. The
burning behaviour and weight loss values of all the fabrics were evaluated using
the standard vertical flammability test method. The results evaluated using an
SPSS statistical program show that the flame retardant concentration, curing
temperature and curing time are very important parameters to obtain FR fabrics
having good flame resistance and acceptable handle and appearance
