Investigation of weave influence on flame retardancy of jute fabrics

Abstract In the present work, seven different weave-structured jute fabrics were treated using an organophosphorus-based flame-retardant (FR) chemical (ITOFLAM CPN) along with a cross-linking agent (KNITTEX CHN) by the pad–dry–cure method. The flammability properties were determined by vertical and horizontal flammability tests and limiting oxygen index (LOI). The flame-spread and after-glow time in the vertical flammability test were calculated to be zero seconds on the FR-treated fabrics while the untreated fabrics were completely burnt. The burn rate in the horizontal flammability test is also measured at zero seconds on the FR-treated fabrics. The highest LOI (43.33) is found in the Twill-3/1 and 4-ends Irregular Satin fabrics, while other fabrics had similar LOI (40) results after FR treatment. The maximum char…
