摘要 为了更好地通过近红外光谱法快速检测服装的纤维含量,有效保护消费者的合法权益,选取校正模型稳定性较高的棉/氨纶、聚酯纤维/氨纶、棉/聚酯纤维模型作为研究对象,通过与常规试验法进行分析比较,分析样品的差异对近红外光谱法试验结果的影响。结果表明:棉/氨纶、聚酯纤维/氨纶模型试验结果不受颜色影响,而棉/聚酯纤维模型深颜色样品试验结果有偏离,建议近红外光谱法与常规试验法相结合;棉/氨纶、聚酯纤维/氨纶、棉/聚酯纤维模型受厚度影响,透光的样品按4层进行试验,得到的结果更准确;棉/氨纶、聚酯纤维/氨纶模型试验结果不受织物组织结构影响,而棉/聚酯纤维模型分布均匀的样品可采用近红外光谱法,对两面组织结构不同、分布不匀的样品不建议采用近红外光谱法;覆膜或含黏合剂的样品,不适用于快速检测,均需先去除膜或黏合剂,再进行试验。 In order to better and quickly detect the fiber content of clothing by near infrared spectroscopy(NIR)and effectively protect the legitimate rights and interests of consumers,cotton/spandex,polyester/spandex and cotton/polyester fiber models with high stability of correction models were selected as the research object,and the influence of sample differences on the test results of NIR spectroscopy was analyzed and compared with conventional test methods.The results show that the cotton/spandex and polyester/spandex models were not affected by color,while the cotton/polyester models were different from the dark color samples.It was suggested to combine NIR with conventional test methods.The cotton/spandex,polyester/spandex,cotton/polyester models are affected by thickness,and the transparent samples are tested by 4 layers,and the results are more accurate.The results of cotton/spandex and polyester/spandex model tests are not affected by fabric structure,and the samples with uniform distribution of cotton/polyester fiber models can use NIR spectroscopy,and the samples with different structure and uneven distribution are not recommended to use NIR spectroscopy.Samples covered with film or containing adhesives are not suitable for rapid detection,and the film or adhesive must be removed first.
