摘要
采用有机膦系阻燃剂N-羟甲基-3-(二甲氧基膦酰基)丙酰胺(ProvatexCP),对真丝织物应用轧烘焙洗技术进行阻燃整理,产品限氧指数可达30%以上,具有良好的阻燃效果;织物有一定程度的泛黄,强力有所下降,但不影响其服用性能。通过阻燃前后广角X射线衍射分析、热重分析、差示扫描量热分析和氨基酸分析等,探究了阻燃机理,认为有机膦系阻燃剂主要与真丝上酪氨酸、赖氨酸、组氨酸反应,且反应主要发生在丝纤维的无定形区;通过热分析可知,丝纤维在受热时,在着火点(600℃)以下便裂解为难燃物质,从而阻止了进一步燃烧。
The paper mainly deals with flame resistance of silk fabric treated with N-hydroxymethyl (3-dimethoxylphosphono) propionamide (Pyrovatex CP) using pad-dry-cure-wash method. The Limited Oxygen Index (LOI) value of the modified sample is above 30%,and can withstand 50 laundry cycles. The reaction degree of flame retardant with silk is high, almost all tyrosine has taken part in the reaction, which can be confirmed by amino acid analysis. Wide-angle X-ray diffraction patterns (WAXD) show that the reaction between flame retardant and silk only occurs in the amorphous region of silk fiber. The mechanism of flame resistant finish with Pyrovatex CP is investigated by thermogravimetric analysis (TGA) and differential scanning colorimetry (DSC)analysis. The treatment has a little effect on the whiteness.
