Application of flame retardant products to knitted fabric

The 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.
