摘　　要：为实现棉涤氨三组分混纺织物纤维成分含量快速定量分析,采集138个样本的近红外光谱信号,使用模型集群分析方法剔除异常样本,筛选出46个关键波长,利用偏最小二乘法建立了棉涤氨三组分混纺织物纤维成分含量定量分析的预测模型。所建立模型的校正系数为0.96,交互验证均方残差为4.50,预测误差均方根为4.59,可满足定量分析的精度要求。In order to achieve rapid quantitative analysis of fiber component content in cotton polyester span- dex three components fabric, near infrared spectroscopy signature of 138 samples were collected. Model population analysis method was adopted to eliminate the abnormal samples. 46 key wavelengths of the samples were screened out. The forecasting model of the rapid quantitative analysis fiber component content in cotton polyester spandex three components fabric was established by using partial least squares method. Correction factor of the established model is 0.96 ,cross-validation mean square residuum is 4.50 and prediction error root mean square is 4.59. The model can meet the precision requirement of quantitative analysis.
