1、 The main functions and applications of fiber accessories:

Fiber accessories of X-ray diffractometer: Using X-ray diffraction (transmission) method, the orientation and crystal structure of the sample are tested by analyzing the crystallinity, half peak width and other data of the fiber.

Fourier transform infrared spectrometer fiber accessories: including microscope, diffuse reflectance, attenuated total reflectance (ATR) and other accessories, used for fiber composition identification, blending ratio determination, single fiber analysis, etc. For example, micro infrared can identify single two-component fibers, and ATR attachments are suitable for surface structure analysis without the need for sample preparation

2、 Common types and characteristics of fiber accessories:

X-ray diffractometer specific accessories: such as small angle diffraction accessories, parallel light thin film accessories, in-situ high/medium low temperature accessories, etc., suitable for different testing requirements. Some instruments support functions such as automatic sample changers and rotating sample tables to improve testing efficiency.

Infrared spectrometer accessories: including transmission sampling tools (such as potassium bromide compression device), micro infrared accessories (for single fiber analysis), diffuse reflection scaffolds (suitable for opaque fibers), and ATR accessories (for rapid non-destructive testing), etc.

3、 Typical application scenarios of fiber accessories:

Material research: Analyze the crystal structure and molecular orientation of natural fibers (cotton, linen, etc.) and chemical fibers (polyester, acrylic, etc.).

Industrial quality inspection: used for determining the blending ratio of textiles and optimizing fiber processing technology (such as tensile orientation monitoring).

Research field: Study the dichroism of polymers, fiber micro area stretching orientation, etc.

In summary, fiber accessories are indispensable tools in material analysis and fiber testing, and their development relies on advances in instrument technology (such as XRD, FTIR) and innovation in accessory design. The specific selection depends on the testing requirements (such as crystal structure, composition identification) and instrument model.
