Fiber accessories are tested for their unique crystal structure using X-ray diffraction (transmission) method. Test the orientation of the sample based on data such as fiber crystallinity and half peak width. Fiber accessories have a wide range of applications in various fields, including materials science, biomedicine, chemical engineering, nanotechnology, geological exploration, environmental monitoring, and more.

Polymers are commonly synthesized as fibers, sheets, and other solid forms. Its properties are greatly affected by its structural parameters such as crystallinity, crystal structure and orientation, and can be studied using XRD

By X-ray diffraction of the material and analysis of its diffraction pattern, information such as the composition of the material, the structure or morphology of the internal atoms or molecules is obtained.
