有机硅柔软整理对羊毛织物燃烧性能的影响

Effect of Silicone Softening Finishing on the Combustion Performance of Wool Fabric

采用有机硅柔软剂对羊毛织物进行柔软整理,研究其燃烧性能的变化。通过自动氧指数仪、扫描电镜、红外光谱仪、热重分析等测试方法对柔软整理后羊毛的表面形貌、元素组成、燃烧性能及热裂解行为进行表征和测试。结果表明,经过柔软整理后的羊毛织物极限氧指数下降了近7%,羊毛由难燃纤维变为易燃纤维,燃烧后残渣量显著减少。有机硅柔软剂使羊毛表面碳链增多,裂解温度下降,羊毛燃烧更加完全。

The combustion performances of wool fabrics after softening finishing by silicone softener were investigated. The combustion performance, surface morphology, element composition, and thermal degradation, of finished wool fabrics were characterized and analyzed by auto oxygen index, scanning electron microscopy（SEM）, infrared spectrometer（FT-IR） and thermogravimetric analysis （TG）, respectively. The results showed that the limiting oxygen index（LOI） of the finished wool fabrics decreased about 7% compared with original ones, and the wool turned out to be ignitable fibers after softening finishing. The residual of wool was significantly reduced after burning. The carbon chains on the surface of wool were increased after the treatment. The pyrolysis temperature of treated wool fabric was decreased, which made the wool burned completely.
