摘　　要：针对用传统方式检测纺织品中禁用染料操作难、成本高、耗时长、危害大等弊端,以禁用染料酸性红26为例,采用可见反射光强光谱分析法与化学计量学结合,基于斜投影建立了一种纯羊毛毛线中酸性红26的定量分析方法。结果表明:纯羊毛毛线中酸性红26的含量在0.17~5.11mg/g范围内时,与利用斜投影算法从混合组分信号中切割出的酸性红26的信号线性关系良好,所建立标准曲线方程的决定系数为0.9958,相对标准偏差为1.79%;利用该方法预测未知样本中酸性红26的含量,预测值与真实值的相对误差均小于10%,该方法分析速度快,且分析过程操作简单,可实现对酸性红26的无损检测。In order to overcome the shortcomings of conventional methods for detecting banned dyes on textiles of difficult operation, high cost, long time and great hazard, a quantitative analysis method of Acid Red 26 on wool thread was established based on the oblique projection construction algorithm using the combination of visible reflection intensity spectrum analysis and chemometrics. The results show that the linear degree of the standard curve equation is high in the range of 0.17-5.11 mg/g (coefficient of determination is 0.995 8, relative standard deliation is 1.79%). The relative error about the content of Acid Red 26 in the unknown sample is lower than 10%. The detection method is simple in operation, high in detection efficiency, and realizes rapid non-destructive detection of Acid Red 26.
