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-centrolled laser scattering intensity testing system are compared with that of the data obtained by microprojector method The results show that the algorithm is feasible for assessig the fiber ODFs of nonwoven fabrics manufactured by different processing methods.
