Measuring Fiber Orientation in Nonwoven Fabrics by Laser Scattering Method Part II: Algorithm and Verification

摘要

The algorithm for evaluation of fiber orientation distribution function (ODF) by laser scattering method based on 2 - dimentional model of fiber arrangement and the method of determining diffuse scattering intensity are presented. the fiber ODFs of nonwoven samples measured by the computer-program-controlled laser scattering intensity testing system are compared with that of the data obtained by microprojector method.
