Near-infrared spectroscopy technology is based on molecular vibration spectroscopy characteristics. By analyzing char- acteristic absorption peaks, it enables non-destructive and rapid detection of key indicators such as fiber composition and moisture content. The detection time is reduced to the second level, and no chemical reagents are required. Due to its high speed, non-de- structive nature, and high accuracy, NIR spectroscopy has been widely applied in the field of textile inspection and testing. This paper introduces the principles and characteristics of NIR spectroscopy detection, comparing its advantages and disadvantages with traditional component detection methods. It outlines the current applications of NIR spectroscopy in textile inspection and testing from the perspectives of qualitative identification, quantitative analysis, and online detection. The focus is on analyzing research progress in spectral data preprocessing and feature extraction algorithms, classification models (qualitative), chemometric models (quantitative), and the integration of multimodal models. Additionally, this paper discusses technical bottlenecks and prospects, pro- viding theoretical support and technical reference for textile testing institutions, inspectors, and academic researchers. The aim is to promote the transformation of the textile industry toward intelligence and sustainability.
