Abstract: Intumescent coatings containing Branched-Polyethyleneimine (BPEI) and mixture of Ammonium Polyphosphate (APP) solution and aqueous kaolin clay were successfully applied on polyester and polyester/cotton fabric via layer-by-layer technique to enhance flame retardancy and anti-dripping of fabric. SEM micrographs of 3, 5 and 7 bilayers coated fabric affirmed that the coat layer on the fabric was rather thin. UL-94 rating of Vertical burning of Thin Material (VTM 0) showed that the flame retardancy of coated polyester and polyester/cotton fabric including self-extinguishing ability and anti-dripping were improved as compared with uncoated fabric. TGA thermogram also revealed that thermal stability of coated fabrics increased when the number of bilayer increased. The porous and slight expanded char layers of the char residue of the coating observed by SEM micrographs demonstrated that LBL coated fabric exhibited the typical structure of intumescent behavior. This research provides a basic method of intumescent coating for self-extinguishment and anti-dripping on polyester and polyester/cotton fabric.
