Abstract:

In order to endow the cotton fabric with high efficiency flame retardant properties, a new low-cost and green approach was presented for constructing ternary composite coating on cotton fabric through spray-assisted layer-by-layer self-assembly of 3-aminopropyltriethoxysilane, sodium alginate and ammonium polyphosphate in aqueous solutions. The surface morphology, flammability and thermal degradation properties of the cotton fabrics before and after coating were investigated by scanning electron microscopy, thermogravimetric analysis, vertical flame tests and microscale combustion calorimetry. The results show that coated cotton fabrics self-extinguish instantly when the ignition source is removed, and its limit oxygen index reaches 35.7% together with good washing resistance. High structural stability and flame retardant property are attributed to the external well-constructed flame retardant composite multilayers and phosphorus-silicon-nitrogen synergism on the degradation process and char yield. Such green and scalable strategy for the design and fabrication of self-extinguishing intumescent coating could also be employed for treating various other cellulose fibers.

Key words: cotton fabric, functional fabric, flame retardant property, layer-by-layerself-assembly, flame retardant coating
