3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 Calibration database calibratedlibrary A database consisting of a set of near-infrared spectra and calibration values of cashmere samples involved in calibration. 3.2 calibrated sample Samples that pass verification during the calibration process. Note. The calibration sample is used as the verification material for calibration in this document. 3.3 Sampleoutsidelibrary sampleoutsidelibrary The standard deviation of the spectrum does not exceed the set threshold and the error of the property value is less than the maximum allowable value of the reproducibility of the calibration method, and the spectral similarity is greater than the set value. Samples that mark the boundaries of the database. 3.4 outliersample Samples that failed verification during calibration. Note. Include samples whose spectral standard deviation exceeds the set threshold or whose property value error is greater than the reproducibility of the calibration method.

4 Principles

Based on the correlation between the change of the net cashmere rate of the sample and the change of its molecular spectrum, a multivariate analysis method was used to establish a spectroscopic determination of net According to the calibration curve of the cashmere ratio, measure the spectrum of the sample to be tested to obtain the net cashmere ratio. ......
