Speculations have it that phthalonitrile imparts flame retardancy on substrates. This study aimed to investigate the activities of phthalonitrile as flame retardant on 100% cotton fabric. The fabric samples tested were cut into 25:4 x 7 cm pieces, scoured, dried, and weighed. They were then impregnated with different concentrations of phthalonitrile in different solvents (benzene and acetone) and emulsion alongside alum dissolved in water. At the same time, the untreated fabric was used as a

The fabrics were subjected to add-on%, after flame time, after-glow time, and % char formation tests. The results showed that cotton-tested flame retardant properties increase with the increase in the concentration of phthalonitrile. Phthalonitrile has flame retardant properties on 100% cotton fabric.
