Fiber Orientation and Aspect Ratio Calculation Using Image Analysis

Abstract

Akio Sakaguchi and Hirokazu Kimura

As a preliminary study of fiber figure evaluation, the methodology of fiber orientation and aspect ratio calculation, especially that used in card webs, is discussed. To determine the fiber direction, the maximum variance method is introduced. In this method, we can derive the fiber’s main direction, which satisfies the criteria of maximum length and minimum width. Moreover, an experimental technique using image analysis is detailed. The results are consistent with the published studies. Thus, this method is viable and has a reliable theoretical background.
