SAFE FLAME RETARDANT NANOCOATING FOR FABRIC USING POLYELECTROLYTE COMPLEXES DEPOSITED FROM WATER
In an effort to impart flame retardant behavior to woven fabrics made from cotton and cotton blends, an environmentally-benign coating method has been developed.Onepot aqueous complexes, containing polyethylenimine (PEI) and poly(sodium phosphate) PSP impart self-extinguishing behavior to cotton-containing fabric.Reduction of total heat release, measured with a microscale combustion calorimeter (MCC), is reduced by more than 80% with just 15 wt% added to a woven fabric 1.An aqueous complex of PEI and ammonium polyphosphate (APP) forms melamine polyphosphate in-situ during exposure to a melamine-containing solution.Nylon-cotton blended fabric was rendered self-extinguishing with less than 20 wt% coating 2.The effectiveness of this halogen-free, flame retardant coating is due to condensed phase activity that includes cooling effects and charring.The ease of this coating procedure and the use of more environmentally benign chemicals deposited from aqueous solutions make this an industrially feasible alternative to current treatments for cotton and cotton-based blends.
