An eco-friendly and effective method to fabricate flame retardant cotton fabrics

To reduce the flammability of cotton fabrics, an environmentally benign, simple and effective method was proposed. Coatings composed phosphoguanidine/ATMP/alginate were deposited on surface fabrics through layer-by-layer (LbL) assembly. FTIR spectra indicate that deposition process is successfully carried out fabrics. TGA suggested LbL coating can significantly increase char residue. The results MCC vertical flame tests showed coatings remarkably enhance fire safety properties a higher concentration ATMP (2 wt%) bring better effect retardancy.
