A new mechano-chemical formulation is developed for making flame resistant sisal fibre rope with low chemical loading. Sisal yarn treated a different of ammonium sulfamate (AS) (50 g/L and 100 g/L) by following dip-dry approach at room temperature. Limiting oxygen index (LOI) measures the minimum amount required in mixture nitrogen burning sample. Treated showed LOI values 28–32 self-extinguish...
