摘　　要：利用自制的新型磷/氮阻燃剂,采用轧-烘-焙工艺对棉织物进行阻燃整理。对整理前后的棉织物进行红外光谱分析、极限氧指数测试、垂直燃烧测试、热重分析、扫描电镜分析及物理性能测试。结果表明:改性后棉织物的阻燃性能和耐热稳定性能得到大幅提升,当阻燃剂质量浓度为300 g/L时,阻燃改性棉织物的极限氧指数达到33.4%,损毁长度缩短,无续燃时间和阴燃时间;炭残留量大幅增加,耐热稳定性能提升;阻燃改性后棉织物表面形貌未发生变化,断裂强力保持良好,白度略微降低。A novel phosphorus/nitrogen flame retardant is used for flame-retardant finishing of cotton fabrics by padding-drying-curing process.The cotton fabrics before and after finishing process are characterized by Fourier-transform infrared spectroscopy,limiting oxygen index test,vertical burning test,thermogravimetric analyze,scanning electric morphology analyze and physical properties test.The test results show that the flame retardancy and thermal stability of the finished cotton fabrics are greatly improved.When the flame retardant is 300 g/L,the limiting oxygen index of the finished cotton fabrics can reach 33.4%,with shorter damaged length,no after-flame time and after-glow time.The residual carbon content is significantly increased,and the heat resistance and stability performance is improved;After flame retardant modification,the surface morphology of cotton fabric is unchanged,and the breaking strength remains good,with a slight decrease in whiteness.
