This application relates to a method for detecting paper fibers, comprising the following steps: mixing the
paper sample to be tested with a
solvent, and dissolving it at a rotation speed of 8000 r / min to 25000 r / min for 1 min to 11 min to obtain a dissolved sample; adding a dye to the dissolved sample to dye the wood and hemp fibers in the dissolved sample to obtain a dyed sample; and performing microscopic detection on the dyed sample to analyze the detection results. Through controllable mechanical
shear force, the wood and hemp fibers in the
paper sample to be tested can be efficiently and fully dispersed, while minimizing the damage to
fiber morphology caused by traditional chemical or high-temperature dissociation methods, laying a physical foundation for subsequent accurate identification. Therefore, this application can rapidly and accurately identify and detect
fiber type and proportion through
dyeing reaction and
microscopic morphology, resulting in more scientific and practical analytical results.
