Technical Field

[0001] The utility model relates to the technical field of mixed fabric fiber determination, in particular to a microscope for determining the fiber content of cotton and linen blended fabrics. Background Technique

[0002] Cotton and linen blended fabrics have become a popular fabric in the modern textile market due to their advantages such as air permeability, moisture absorption, antibacterial and mite-proof, durability, anti-wrinkle, environmental protection and health, and diverse styles.

[0003] However, in daily textile testing operations, both linen and cotton are plant cellulose fibers. After blending, their component content cannot be determined by chemical analysis methods, nor can they be separated by mechanical methods. The current detection technology is to use an ordinary biological microscope, a microprojector or a digital image analyzer to distinguish and count a certain number of fibers, and use a microprojector or a digital image analyzer to measure the diameter or cross-sectional area of the fibers to calculate the weight percentage content of various fibers.

[0004] However, after the cotton and linen fiber blend is sliced, adding iodine solution to the mixed fibers can make the nodes of the linen fibers more obvious. However, when testing the treated linen fibers, the smaller morphology of the fibers is difficult to present, the fiber state shown is highly similar to that of cotton, the imaging is not clear, and the determination effect is affected. Summary of the Invention

[0005] In view of the deficiencies of the above-mentioned prior art, a microscope for determining the fiber content of cotton and linen blended fabrics is provided, so that the visual imaging is the morphology after polarization. On the one hand, the fiber dyeing state will change, and the fiber types can be distinguished by the imaging color. On the other hand, the smaller morphology of the fibers will be presented.

[0014] The beneficial effect of the microscope of the present utility model for determining the fiber content of cotton-linen blended fabrics is that a polarizing component is installed in the imaging area on the upper part of the microscope body, and the visual imaging is the form after polarization. On the one hand, the fiber dyeing state will change, and the fiber types can be distinguished by the imaging color. On the other hand, the smaller form of the fiber will be presented, such as the fine nodes of hemp.

[0015] A condenser is provided at the light source position of the microscope body. By rotating the condenser to adjust the light transmission intensity, it is possible to observe more clearly some forms of the fibers. For example, when the nodes of hemp fibers are not obvious, the light transmission can be adjusted so that the bottom plate is dark and only the fiber part is bright. At this time, the faint bamboo joints of hemp can be clearly seen, thus determining it as hemp. Description of the Drawings

[0022] The following will combine the accompanying drawings and specific embodiments to make a detailed description of the present utility model.

[0023] Embodiment 1

[0024] As Figures 1-5 shown, a microscope for measuring the fiber content of cotton and linen blended fabrics includes a microscope body 1. An insertion slot 3 is provided on the objective turret base 2 of the microscope body 1. An insertion plate 4 that can be inserted into the upper imaging area of the microscope body 1 is provided in the insertion slot 3. A through slot 5 is provided on the insertion plate 4, and a polarization component is provided above the through slot 5.

[0025] The polarization component includes a positioning plate 6. A fixing slot 16 is provided on the positioning plate 6. A polarizing lens 7 is provided in the fixing slot. A receiving slot 8 for receiving the positioning plate 6 is provided on the insertion plate 4. The through slot 5 is provided at the bottom of the receiving slot 8.

[0026] A first positioning magnet 9 is provided at the bottom of the positioning plate 6, and a second positioning magnet 14 corresponding to the first positioning magnet 9 and used for attracting and combining with the first positioning magnet 9 is provided at the bottom of the receiving slot 8. It also includes a positioning member for preventing the displacement of the positioning plate 6 after the first positioning magnet 9 and the second positioning magnet 14 attract and combine the positioning plate 6 and the receiving slot 8. The positioning member includes a positioning slot 10 provided at the bottom of the receiving slot 8 and a positioning block 11 provided at the bottom of the positioning plate 6 for cooperating with the positioning slot 10. A fixing component for fixing the insertion plate is provided on the objective turret base 2. The fixing component includes a positioning screw hole 12 provided on one side of the insertion slot 3, and a tightening bolt 13 provided in the positioning screw hole 12 for pressing the insertion plate 4 against the slot wall of the insertion slot. By providing the first positioning magnet 9, the second positioning magnet 14, the positioning block 11 and the positioning slot 10, the positioning plate 6 can be quickly positioned and fixed in the receiving slot 8 to prevent the displacement of the polarizing lens 7. By providing the fixing component, the displacement of the insertion plate is prevented.

[0027] After the cotton and linen fibers are blended and sliced, adding iodine solution to the mixed fibers can make the nodes of the hemp fibers more obvious. However, when testing the treated hemp fibers, the nodes of many hemp fibers are not obvious, and the fiber state shown is highly similar to that of cotton. By installing a polarization component in the upper imaging area of the microscope body, the visual image is the morphology after polarization. On the one hand, the fiber dyeing state will change, and the fiber types can be distinguished by the imaging color. On the other hand, the smaller morphology of the fibers will be presented, such as the fine nodes of hemp.

[0028] Embodiment 2

By rotating the condenser 15 to adjust the light transmittance, some fiber morphologies can be observed more clearly. For example, when the nodularity of hemp fibers is not obvious, after adjusting the light transmittance, the bottom plate can be made dark, and only the fiber part is bright. At this time, the faint bamboo joints of hemp can be clearly seen, so as to determine it as hemp. The condenser 15 is a prior art and will not be described again here.
