LBL generated fire retardant nanocomposites on cotton fabric using cationized starch-clay-nanoparticles matrix

Abstract Egg white proteins (W) in combination with hypophosphorous acid (HA) were investigated for making flame retardant coating over cotton fabric adopting layer by layer (LbL) assembly technique. A novel phosphorous-nitrogen based non-inflammatory pathway was produced due to strong electrostatic interactions between egg white protein and HA. The coated cotton fabric was characterized using FESEM, ATR-FTIR, TGA and flame tests. Vertical flame test (VFT) and BS EN ISO 15025 tests were performed to understand the combustion pattern of coated fabric. The cotton fabric coated with egg white protein followed by HA (CTW+HA) showed self-extinguish properties with fragile char structure, whereas uncoated fabric was completely burnt with ash residue. Thermogravimetric analysis revealed that initial decomposition temperature of coated fabric got lowered but raised the char residue at 800 ℃. Moreover, surface morphology after VFT of CTW+HA showed swollen char structure that prevented the interaction of combustible products with oxygen and heat. Thus, the developed coating could serve as excellent fire retardant due to the synergistic effect of HA and egg white protein.

Fabric Finishing

A series of novel fire-retardant agents, fluorocyclotriphosphazene derivatives with the substitution groups of 2,2,3,3-tetrafluoropropoxy groups were synthesized using hexachlorocyclotriphosphazene and 2,2,3,3-tetrafluoropropyl alcohol as starting materials. The synthesized fire-retardant agent was emulsified and applied on the cotton fabric finishing to reduce the flammability and afford water/oil repellency simultaneously. The optimum finishing process was achieved according to the test of cotton finishing with fluorocyclotriphosphazene. The treated cotton showed not only excellent fire-retardant performance, but also water and oil repellency with little change in strength and whiteness.
