Development of durable flame retardant textiles and the exploration of alternate methods to achieve the same has remained an important quest for research. In the present work, the efficacy of sulphamic acid, which is nitrogen and sulphur-containing compound, was studied as a flame retardant for wool. The flammability characteristics of wool fabrics were evaluated by limiting oxygen index (LOI), vertical flammability test as also by the total heat released and the heat release rate. The elemental analysis of fabrics and char were done using EDX and CHNS. The changes in the chemistry of the modified wool were characterised by FTIR spectroscopy. In addition, the durability of the finish against repeated home launderings up to 30 washes has been reported. Sulphamic acid has been found to be an efficient flame-retardant for wool. Durability of the treatment was significantly improved when treated along with 1,2,3,4-Butane tetracarboxylic acid (BTCA).

耐用阻燃纺织品的开发以及探索实现相同目的的替代方法的探索仍然是重要的研究追求。在当前的工作中，研究了氨基磺酸氨基磺酸氨基磺酸作为羊毛的阻燃剂的功效。羊毛织物的可燃性通过极限氧指数（LOI），垂直可燃性测试以及总释放热量和放热率进行评估。织物和炭的元素分析是使用EDX和CHNS进行的。FTIR光谱表征了改性羊毛的化学变化。另外，已经报道了整理剂对重复洗涤多达30次的耐久性。已发现亚硫酸是羊毛的有效阻燃剂。
