Abstract

The invention provides a novel nondestructive and clean near-infrared textile content prediction method and model. A spectral unmixing theory is introduced into qualitative and quantitative analysis of textile components for the first time, and a textile fiber component unmixing method based on near-infrared spectral data is provided, namely, a fully constrained least square (FCLS) linear component unmixing method is provided. The near-infrared textile content prediction method comprises a data marking module, a near-infrared spectrum-based data preprocessing model, a textile qualitative analysis module, an FCLS-based composition mixing core module and a quantitative result error analysis module. A linear component decomposition mixing method based on a fully constrained least square algorithm (FCLS) is realized, and component prediction of single components and multiple components of fibers of various textile fiber pure materials and blended textiles is realized; the accuracy of model component analysis and prediction is improved; the method realizes rapid, lossless and clean detection of the textile components, and is high in accuracy and easy to operate.

Description

technical field [0001] The invention belongs to the field of textile component analysis, and in particular relates to a qualitative and quantitative analysis method for non-destructive cleaning of near-infrared textile fiber components by using a component unmixing method. Background technique [0002] In recent years, with the improvement of people's living standards, the requirements for the quality of textiles have also been continuously improved. A large number of textile components in the market are unclearly marked and the quality is uneven, which has triggered a high demand for textile component analysis. At present, the analysis methods of textile fiber composition mainly adopt chemical dissolution method and physical analysis method traditionally. [0003] The chemical dissolution method has great limitations, and is not suitable for qualitative and quantitative analysis of fibers with similar physical and chemical structures, and cannot be fully satisfied with cer...
