Abstract
The objective of this study was to develop and apply a
simple method for MFA measurement and use it for fibers
with different morphology and some mechanical
deformations.In this study, only fibers with significant
sinusoidal light intensity curves were evaluated. The
assessed MFA is an average value from all wall layers and
structures in the polarised light beam. In thickwalled
latewood fibers, the oriented S2-layer dominates, and low
angles are measured with high light intensity differences
between maximum and minimum intensity values within a
90°-range of polarisation filter position (for intensity
difference see Figure 4). In thinwalled earlywood fibers,
the S2-layer is much thinner, and the S1- and S3-layers
affect the result much more than for latewood fibers.
Subsequently, the resulting measured MFA shows higher
values for this type of fibers. Due to the lower fiber
wall mass, the intensity difference is also smaller.
