Embodiment 1
[0020] (1) Detection of the longitudinal section of the fiber: the fiber is placed flat on the gelatin film, then the fiber and the gelatin film are clamped in the middle with two metal plates, and after the above-mentioned two metal plates are fixed (two metal plates The force between the plates is 1.5bar), heated to 100°C for drying, and the drying time is 30min. After heating, put it into the refrigerator to cool; finally, the fibers are removed from the gelatin film, and the gelatin film Obtain the imprint map of the longitudinal section of the fiber;
[0021] (2) Detection of fiber cross-section: stick the fiber to the bottom of the container with a starch adhesive, and then add the resin mixture (polyester resin 98-99%, benzoyl peroxide 2-1%) in the container, Then heat to 70°C and dry for 60 minutes to polymerize the resin mixture, and after cooling at room temperature, cut out slices with a thickness of 12 μm, and finally glue the obtained slices on glass slides and pu...
Embodiment 2
[0023] (1) Detection of fiber longitudinal section: place the fiber flat on the polystyrene film, then sandwich the fiber and the polystyrene film with two metal plates, and fix the above two metal plates (the force between the two metal plates is 2.0bar), heated to 100~125°C for drying, the drying time is 15~30min, after heating, put it into cooling device to cool immediately; After removing it from the styrene film, the imprint map of the longitudinal section of the fiber can be obtained on the polystyrene film;
[0024] (2) Detection of fiber cross-section: use adhesive to stick the fiber to the bottom of the carton with a side length of 40-60mm, then add the resin mixture into the carton, and then heat to 80°C to dry, the drying time is 40min, Polymerize the resin mixture and cool it at room temperature, cut out slices with a thickness of 18 μm, and finally glue the obtained slices on a glass slide and put them in cedar oil for microscope observation.
