Environmentally friendly flame retardant chemicals are being developed in recent studies as legislation for eco-sustainable textile production becomes more stringent around the world. Utilisation of waste generated by wool spinning industry is a prime concern with present work. The extraction and modification keratin from cotton has not been attempted previously. research describes unique method using chemically modified derived an environmentally acceptable nitrogen/phosphorus containing fabrics. Melamine sodium pyrophosphate were used nitrogen phosphorus sources, respectively, along glyoxal cross-linking agent. improved thermal stability treated fabrics was confirmed TGA, while structural changes established FTIR XRD analyses. Due to synergistic impact phosphorous, resulted formation continuous intact layer char that confers retardancy on cotton. limiting oxygen index after application showed nearly 66.7% increase compared untreated Overall, findings paper show sustainable approach combines utilisation one sector (minimizing solid industry) management elements add value another (multifunctional finishing agent industry).
