In order to develop a kind of color-fasten and durable flame retardant wool fibers, the green and environmentally friendly dye, i.e. sodium copper chlorophyll (SCC) was firstly used to dye the wool fibers, then the dyed wool fibers (DW) was phosphorylated with phosphoric acid to obtain flame retardant wool fibers (FR-W). The results show that FR-W has good color fastness, and the limiting oxygen index (LOI) of FR-W is still as high as 29.6% after 50 times washing, indicating excellent durable flame retardant performance. The char residue of FR-W at 800 °C under air atmosphere is 27 wt%, showing good char forming ability. Compared to the control sample, the peak of heat release rate (pHRR) of FR-W decreases by 65% and the total heat release (THR) of FR-W decreases from 5.2 MJ/m² to 4.8 MJ/m². The SCC combined with phosphate groups play the role of gas and condensed phase flame retardant mechanism.

为了开发一种色牢耐久的阻燃羊毛纤维，首先使用绿色环保的染料，即叶绿素铜钠盐（SCC）对羊毛纤维进行染色，然后将染色的羊毛纤维（DW）磷酸化。用磷酸制得阻燃羊毛纤维（FR-W）。结果表明，FR-W具有良好的色牢度，洗涤50次后，FR-W的极限氧指数（LOI）仍高达29.6％，显示出优异的耐久阻燃性能。FR-W在空气气氛下于800°C时残留的焦炭含量为27 wt％，显示出良好的焦炭形成能力。与对照样品相比，FR-W的放热速率（pHRR）峰值降低了65％，FR-W的总放热（THR）从5.2 MJ / m ²降低至4.8 MJ / m ²。SCC与磷酸酯基团结合起到气相和缩合相阻燃机理的作用。
