Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard was proposed by the China National Textile and Apparel Council. This standard is under the jurisdiction of the Basic Standards Branch of the National Textile Standardization Technical Committee (SAC/TC209/SC1). Drafting organizations of this standard. Zhongshan Entry-Exit Inspection and Quarantine Bureau, Jiangxi Entry-Exit Inspection and Quarantine Bureau, Guangdong Entry-Exit Inspection and Quarantine Bureau, China Textile Standard Inspection and Certification Co., Ltd., Guangzhou Fiber Products Testing and Research Institute. The main drafters of this standard. Wang Jingli, Gui Jiaxiang, Zhang Xiaoli, Han Yuru, Yang Xinhui, Zhao Zhenyu. Textile fiber quantitative analysis near infrared spectroscopy

1 Scope

This standard specifies a method for the determination of fiber content in textiles using near-infrared spectroscopy. This standard applies to textiles other than coated fabrics, pigment printing fabrics and inorganic fibers.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Near-infraredspectra Molecular spectrum with a wavelength of about 780nm~2500nm (or a wavenumber of about 12820cm-1~4000cm-1). 3.2 Calibrationmodel A mathematical expression that expresses the relationship between the fiber content of a set of samples and their spectra. 3.3 Calibrationsample The fiber content data is known and used to build the sample for the calibration model. 3.4 Validationsample The fiber content data is known and it is a sample used to verify the performance of the model. 3.5 Referencemethod The method used to determine the fiber content of the calibration sample and verify the sample is usually a standard method or a recommended method. Note. The methods for determining fiber content in international, national or industry standards, such as chemical analysis, physical analysis (manual split method and microscope method), etc. 3.6 Referencevalues The fiber content value of the calibration sample or verification sample measured by the reference method. 3.7 Model validation The process of verifying the consistency between the test value of the calibration model and the reference value with the verification sample. ...
