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. A specialized component used for analyzing fiber materials such as textiles, polymer fibers, biological fibers, etc. It is commonly used to study the crystal structure, orientation, and molecular arrangement of fibers.
Main functions of fiber accessories:
1. Fiber sample fixation: Fiber accessories are used to fix the fiber sample, ensuring its position and direction stability in the X-ray beam.
2. Fiber orientation analysis: By adjusting the position and angle of the sample, the crystal orientation and molecular arrangement of the fibers are studied.
3. Small angle X-ray scattering (SAXS): Some fiber attachments support SAXS for analyzing the nanoscale structure of fibers.
Common types of fiber accessories:
1. Fiber stretching device: It can apply tension to fibers during XRD analysis to study structural changes under stress.
2. Rotating sample stage: allows fiber samples to rotate, facilitating the collection of diffraction data from different angles.
3. Temperature control accessories: used to analyze fiber materials at specific temperatures and study the effect of temperature on structure.
Application fields of fiber accessories:
1. Materials Science: Study the crystal structure and mechanical properties of synthetic fibers such as nylon and polyester.
2. Biomaterials: Analyze the structure of natural fibers such as collagen and cellulose.
3. Textiles: Evaluate the orientation and crystallinity of textile fibers.
Steps for using fiber accessories:
1. Sample preparation: Fix the fiber sample onto the attachment.
2. Adjust parameters: Set the X-ray source, detector, and sample positions.
3. Data collection: Collect diffraction patterns.
4. Data analysis: Use software to analyze diffraction data and obtain structural information.
Matters needing attention:
-Sample alignment: Ensure that the sample is accurately aligned with the X-ray beam.
-Parameter optimization: Optimize X-ray energy, exposure time, etc. based on sample characteristics.
-Data quality: Ensure clear diffraction patterns and avoid noise interference.
