| Abstract:Fiber furnish analysis is one of the commonly used methods for paper identification and paper fiber analysis. It primarily involves qualitative determination based on the coloration of fibers after staining and their morphological characteristics， followed by quantitative measurement of the mass proportion of each fiber type through the application of quality factors. However， the accuracy of fiber furnish analysis results can be significantly influenced by various factors， including sample condition， staining reagents， and staining procedures. Moreover， the method demands a high level of technical skill and practical experience from analysts， which to some extent limits its broader promotion and application. To deepen the understanding of fiber furnish analysis technology， this paper systematically reviewed its technical mechanism and key procedural steps. A focused comparison was provided between Herzberg stain and Graff “C” stain， covering their chemical compositions， staining characteristics， and respective scopes of applicability. Furthermore， the physicochemical factors affecting staining performance were analyzed in detail. The applications of this analytical method in industries such as paper manufacturing， ancient book restoration， forensic identification， and transportation infrastructure were also introduced. Finally， the future development trends of fiber furnish analysis technology were discussed， with consideration of advancements in artificial intelligence and evolving environmental sustainability policies. |
