| 摘 要： | The scattering performance of a parallel laser beam onthe parallel fiber model and nonwoven fabrics are studiedin detail. A device of computer - program - controlledsystem for measuring laser scattering intensity - angledistribution function of fiber assemblies is set up, and themeasuring condition for distingulslhing the fibers ar-ranged at different directions is carried out. The materi-als of two categories, the models of fiber assembly andnonwoven fabrics made with varied processing methods,are studied. The analysis and experiments show that thefiber orientation distribution functions in the 2 - dimen-sional fiber assemblies can be sensitively determined bylaser scattering method.

| Abstract: | The scattering performance of a parallel laser beam on the parallel fiber model and nomvoven fabrics are studied in detail. A device of computer - program - controlled system for measuring laser scattering intensity - angle distribution function of fiber assemblies is set up, and the measuring condition for distinguishing the fibers arranged at different directions is carried out. The materials of two categories, the models of fiber assembly and nonwoven fabrics made with varied processing methods, are studied.
