Fiber Accessories utilize the X-ray diffraction (transmission) method to analyze the unique crystal structure of fibers. Parameters such as crystallinity and full width at half maximum (FWHM) are used to determine the orientation degree of the sample. ​ Main Functions and Features of Fiber Accessories: Maintaining Fiber Orientation: This is the most critical aspect. Fibers typically exhibit high anisotropy, with crystals preferentially aligned along the fiber axis. Fiber Accessories can straighten and secure fiber bundles, preserving their original orientation to measure orientation degree and distribution. Adapting to Different Sample Forms: Single Fiber: Extremely thin, requiring special clamps or frames for fixation. Fiber Bundle: Multiple fibers arranged in parallel; Fiber Accessories must align and tension them uniformly. Fiber Fabric: Materials like cloth require a flat frame to stretch them taut. Enabling Special Testing Modes: Transmission Mode: Suitable for thin fiber bundles or single fibers. Fiber Accessories include a dedicated frame to tension the fiber, allowing X-rays to penetrate the sample directly. Reflection Mode: Used for thicker fiber bundles or fabrics. Fiber Accessories provide a flat sample surface for this mode. Fiber Sample Holder: This is a simple metal or plastic frame equipped with slots or knobs. During operation, both ends of the fiber bundle are fixed to the holder, and knobs are rotated to tension the fiber, keeping it straight and parallel. The entire holder can be placed in the XRD goniometer for testing, similar to a standard sample. In summary, Fiber Accessories for XRD are specialized sample fixation devices designed for testing fibrous samples with anisotropic structures. Their core function is to maintain and regulate fiber orientation, while advanced versions may support in-situ stretching and other functionalities, providing critical insights into the orientation of crystal structures in fibers.

XRD and FTIR fiber accessories provide complete material characterization solutions. XRD units analyze crystal structure and orientation, while FTIR systems identify composition through micro-imaging and ATR technology. Accessories include small-angle diffraction, parallel beam thin-film, and in-situ temperature stages for nanoscale analysis. Automated sample handling enhances efficiency. Applications span material research, industrial quality control, and scientific studies of polymer dichroism. These tools continue to evolve, driving innovations in fiber science and industrial applications.
