摘要

为得到分析精度较高的用于检测棉-涤混纺面料里含棉量的近红外光谱分析模型。首先，利用50个棉-涤混纺面料作为对象，自行设计采样装置，采集其近红外光谱，然后，经一阶、二阶导数，Savitzky-Golay滤波等方法预处理，结合偏最小二乘法，建立了四个棉成分的定量分析模型。结果表明：Savitzky-Golay滤波对定标结果几乎没有影响；经一阶导数预处理后的光谱数据结合偏最小二乘法建立的模型具有较高的分析精度，定标均方差和预测均方差分别达到了0.022、0.018，分析误差控制在±0.05以内。基本满足了纺织领域快速定量检测的精度需求。同时，文章还分析了近红外光谱技术在该应用领域的研究重点。

Abstract

In order to establish a calibration that can determine the concentration of cotton in cotton-terylene textile precisely. First

near infrared spectra of 50 cotton-terylene textile samples were collected using self-designed accessory. Savitsky-Goaly filter smoothing

first derivative and second derivative pretreated the spectra. Calibration models for cotton content were established with PLS

The results indicate that Savitsky-Goaly filter smoothing spectra treatments couldn’t effect the performance of the model in this case; NIR technique could analyze the contents in the textile precisely

RMSEC is 0.022，RMSEP is 0.018 and the error of analysis is restricted ±0.05;In addition

several key aspects of this application were expressed.
