Description
技术领域Technical field
本发明涉及纺织物检测技术领域，具体涉及一种红外显微织物纤维无损检测方法。The invention relates to the technical field of textile testing, and in particular to an infrared microscopic non-destructive testing method of fabric fibers.
背景技术Background technique
织物种类多样，包含棉、麻、毛/粘纤面料、丝制品、粘纤、羽绒面料等。织物纤维检测是纺织品检验质量的一项重要考核指标，是服装标识的主要内容之一。织物纤维组分的检测包括定性分析和定量分析，纤维组分的检测依旧按照先定性后定量的传统方法。There are various types of fabrics, including cotton, linen, wool/viscose fabrics, silk products, viscose, down fabrics, etc. Fabric fiber testing is an important assessment index for textile inspection quality and one of the main contents of clothing labeling. The detection of fabric fiber components includes qualitative analysis and quantitative analysis. The detection of fiber components still follows the traditional method of first qualitative and then quantitative.
定性分析是确定样品中所含纤维的种类，通常指纤维成分；定量分析是确定所含纤维的量，通常指纤维含量，Qualitative analysis is to determine the type of fiber contained in the sample, usually refers to the fiber composition; quantitative analysis is to determine the amount of fiber contained, usually refers to the fiber content,
目前纺织纤维定性的检测方法有显微镜观察法、燃烧法、化学溶解法、药品着色法、熔点试验法和红外吸收光谱法等。但这些方法都有一定的局限性。显微镜观察法和燃烧法只能鉴别天然纤维或合成纤维；化学溶解法虽然能鉴别混纺产品，但其使用的有机溶剂对检测人员身体健康有影响，而且还污染环境；红外吸收光谱对测试环境温度要求相当高，制样复杂，检测周期长，不能满足快速检测的要求。而定量的过程,包括试剂的浓度、试验温度、反应时间、设备性能、操作者的经验等都有较高要求。因此,纤维组分检测的过程比较繁琐,检测的结果不确定性比较大。At present, the qualitative detection methods of textile fibers include microscopic observation, combustion, chemical dissolution, pharmaceutical coloring, melting point test and infrared absorption spectroscopy. But these methods have certain limitations. Microscopic observation and combustion methods can only identify natural fibers or synthetic fibers; although the chemical dissolution method can identify blended products, the organic solvents used have an impact on the health of the inspector and pollute the environment; infrared absorption spectroscopy has a negative impact on the test environment temperature. The requirements are quite high, the sample preparation is complex, and the detection cycle is long, which cannot meet the requirements of rapid detection. The quantitative process, including reagent concentration, test temperature, reaction time, equipment performance, operator experience, etc., all have higher requirements. Therefore, the process of fiber component detection is relatively cumbersome, and the detection results are relatively uncertain.
近红外光谱分析技术(NIRS)主要用于800nm～2500nm范围电磁波的无损测量。不同于质谱、色谱分析技术，该技术无需提纯，已广泛应用于食品、农业、医药、炼油与化工等领域。近红外光谱的定性分析是利用已知类别的样品建立近红外光谱鉴别模型，再考察未知样品是否属于该类物质的一种方法，主要用于物质的聚类分析和判别分析。Near-infrared spectroscopy (NIRS) is mainly used for non-destructive measurement of electromagnetic waves in the range of 800nm to 2500nm. Different from mass spectrometry and chromatography analysis technology, this technology does not require purification and has been widely used in food, agriculture, medicine, oil refining and chemical industry. Qualitative analysis of near-infrared spectroscopy is a method that uses samples of known categories to establish a near-infrared spectrum identification model and then examines whether unknown samples belong to this type of substance. It is mainly used for cluster analysis and discriminant analysis of substances.
现有技术中，缺乏利用同时获取高分辨红外光谱及宽谱红外图像，实现对织物纤维的粗织、交织方式等纹理探测，以及成分分析、模式识别的联合检测技术，无法对于特定的小区域的精细的红外光谱分析，无法对视场范围内的检测对象的交织方式的检测等的联合检测。In the existing technology, there is a lack of joint detection technology that can simultaneously acquire high-resolution infrared spectrum and wide-spectrum infrared images to detect textures such as coarse weaving and interweaving patterns of fabric fibers, as well as component analysis and pattern recognition, and cannot detect specific small areas. Detailed infrared spectrum analysis cannot detect joint detection such as interlaced detection of detection objects within the field of view.

When the cutting mirror 10 cuts into the infrared optical axis 15 under the control of the cutting mechanism 11, the infrared microscopic imaging light path works; conversely, when the cutting mirror 10 cuts out the infrared optical axis 15 under the control of the cutting mechanism 11, the Fourier transform infrared spectrum detection light path works. In the infrared microscope imaging mode, the broad-spectrum infrared light emitted by the infrared light source 13 along the infrared optical axis 15 is reflected by the cut-in mirror 10, turns to the cut-in optical axis 16 perpendicular to the infrared optical axis 15, and then is reflected and turned by the total reflective mirror 18. The turning optical axis 23, which is parallel to the infrared optical axis 15, is reflected by the hole mirror B 25 and the hole mirror A 24, then turns to the main optical axis 27 perpendicular to the orthogonal optical axis 7, and then passes through the cassette microscope objective. 31 is focused on the fabric fiber sample 29 on the focal plane.
