The behavior of light backscattering from a fiber assembly with arbitrairy fiber orien tation
distribution in space and area density depends on the physical properties of the fibers and
their arrangement in the fiber assembly. In this paper, a thin fiber layer and its overlapped
models are built to study their relations. With this model, the general equation for
ascertaining backscattering intensity and the normalized backscattering intensity distribution
of light produced from a nonwoven fabric with arbitrary fiber orientation and area density are
derived from the theory of scattering and propagation of light. This allows the influence of
each of these nonwoven structures to be separately studied. The measured results of the
backscattering intensity of light and its distribution by the apparatus initiated in our
laboratory are in good agreement with the analytical results calculated from structures of
actual nonwovens. The instrument is equipped with a computer-controlled system and
displays automatically. The backscattering intensity distribution of light and thus the fiber
orientation distribution and area density of nonwoven labrics can be determined with this
method.
