“…9 Recently, phosphorous-based flame-retardant material has attracted much attention from researchers because of its excellent characteristics and properties, such as low cost, ease of availability, 10,11 resistance to the repeated wash cycle, 12 decreases explosiveness of fuel, increases carbonaceous char and decreases afterglow time. 13 Researchers have developed phosphorous-based flame-retardant materials using thiourea and phosphoric acid (PA), 14 fireproof coatings using casein and ammonium polyphosphate, 15 salts of ammonia and melamine hexa (methyl phosphonic acid), 16 silicon-based flame retardants and superhydrophobic materials, 17 phosphorous nitrogen-based flame-retardant material from glycerol, PA and urea, 18 and they applied them on the surface of cotton fabric to prepare FR cotton fabric. The aforementioned literature showed that the authors created FR material using a time-consuming, multi-step synthetic process and expensive chemicals.…”
