摘要

Flame retardant functionality was imparted in cellulosic textile using spinach leaves juice (SJ), an eco-friendly natural product. The extracted juice was made alkaline and applied in fresh bleached and mercerized cotton fabrics. Flame retardant properties of the control and treated fabrics were analysed in terms of limiting oxygen index (LOI), horizontal and vertical flammability and radiant heat testing. The study showed that the treated fabrics had good flame retardant property compared to control fabrics. The LOI value was found to increase by 1.6 times after application of SJ. As a result of this, the fabric does not catch flame. In horizontal flammability, the treated fabric showed burning with afterglow (without presence of flame) with a propagation rate of 10mm/min, which is almost nine times lower than the control fabric. The thermal degradation and pyrolysis was studied using thermogravimetric analysis. The chemical composition of the control and SJ-treated cellulosic fabric were analysed by FTIR, SEM and EDX. Durability of the flame retardant functionality to soap washing and weathering had also been studied. After application of SJ, cellulosic fabric sample produced natural green colour. There was no significant change in other physical properties.
