摘　　要：为了实现纺织纤维测定的高效化和无害化并将快速检测方法提供给纺织企业、市场监管部门,将281个棉/氨纶混纺样品作为研究对象,分析了样品颜色和织物结构的影响,并采用偏最小二乘法建立了棉/氨纶混纺织物中纤维含量的近红外定量模型。为验证该模型的准确性,对23个棉/氨纶样品进行了预测。通过对该方法与标准方法SN/T 0464--2003进行成对结果t检验,得到了两种方法的结果不存在显著性差异的结论。这种近红外方法已转化为检验检疫行业标准,并经实际应用证明效果显著。In order to realize the high efficiency and harmlessness of textile fiber detection,the rapid detection method is provided to textile enterprises and market regulatory authority.In this paper,281 samples of cotton/spandex blend are taken as the research object,and the influence of sample colors and fabric structures is analyzed.The near-infrared quantitative model of fiber content in cotton/spandex blended fabric is established by the partial least square method.To verify the accuracy of the model,the prediction is made based on 23 cotton/spandex samples.The predicted results are paired with the standard method SN/T 0464-2003 in t-test,and the conclusion that there are no significant differences between the two methods is obtained.The near-infrared method has been converted into the industry standard of inspection and quarantine and proved to be effective in practical application.
