This study deals with the influence of two binder resins (acrylic and styrene-butadiene resins) on the fire properties and the thermal behaviour of cotton and cotton/flame retardant polyester (PESFR) textiles. Lab-scale fire testings (limiting oxygen index and vertical fire test) have shown that the impregnation of the cotton/polyester fabrics leads to a dramatic loss of fire performance. Therefore, a thermogravimetric study (under oxidative and inert atmospheres) of cotton/polyester blends, impregnated or not impregnated, were carried out to understand the interactions between the fabrics and resins. Data of these thermogravimetric analyses (TGA) were then modelled using Invariant Kinetic Parameters methods to determine the kinetics parameters and the modes of degradation of the impregnated fabrics.
