Investigation of Microfibril Angle of Flax Fibers Using X-Ray Diffraction and Scanning Electron Microscopy

摘要

Microfibril angle (MFA) of secondary cell wall has an important effect on the mechanical properties of flax fibers. It is therefore essential to study the relationships between MFA and mechanical properties. This paper investigated MFA of seven flax fibers by using X-ray diffraction (0.6T method) and scanning electron microscopy (SEM; direct observation). The results showed that there is no significant difference between MFA obtained by X-ray diffraction (6.2-7.2 degrees) and SEM (5.8-7.3 degrees). Correlation analysis results showed a good linear correlation (0.9) between two methods.
