Development of Fire Retardant on Jute by Chemical Means

Jute is highly flammable in character. Due to its high degree of flammability, the versatile use of this fibre is handicapped to some extent, particularly in some specific purpose where jute products with flame resistance finishes and demanded. Considering this disadvantage, a research project was undertaken to make this fibre flameproof and therefore safer in specialized textile uses. The study was performed using yarn and fabrics which were desized with diastase and lissapol-N. Yarn and fabrics were scoured with sodium carbonate, sodium hydroxide under some standard conditions. These pretreated yarns and fabrics were used in the whole experimental work. The treated yarns were tested for flame retardant by subjecting them to the luminous flame of Bunsen burner and by observing the time of flaming (after flame) and time of glowing (flameless combustion, after glow), if any Percentage losses of strength of the treated yarn and fabrics were also measured by standard method. Different solutions of fire resistant chemicals were prepared to change the chemical, concentration and pH ratio of the solution. Jute fabrics and yarns treated with 65% solution of urea and ammonium dihydrogen phosphate (the ratio of urea and ADP being 3:2) together with 2% Turpex NP and 3-6% perapret PE-40% were found durably flame retardant causing minimum loss of the strength. This research was focused on fire resistant treatment of jute yarn and fabrics with different chemicals to make jute products for diversified textile uses.
