Effect of Mordant on the Flammability of Fabrics

Abstract

Due to the sensitiveness of textile for flaming and the rate of flame transfusion of fiber, some experiments with natural dyes (e.g. reseda, madder, kermes and pomegranate peel) have been done on cotton, wool and polyester fabric. In these experiments, fabrics were dyeing with natural dyes by bottom chrome method. Considering the standard flame test of material, those cotton fabrics which are dyed by reseda and alum mordant, when the fire is died out, the kind of mordant is an effective parameter. Actually, by increasing the molecular weight of the mordant (e.g. alum mordant) the after glow (A.G.) is decreased. The results indicated that between samples there is a significant difference which can be depend on the kind of mordant and dyes.
