Fiber Crimp Distribution in Nonwoven Structure

The crimp of the textile fibers is very critical to determine its properties and voluminisity. The microscopic characteristic of the nonwoven fabric is totally depends on the linearity and length of the crimp and the amplitude of the crimp. In this review paper we have discussed about the crimp calculation, measurement techniques and the standards used for the textile nonwoven substrates. The crimp frequency (orientation distribution function; ODF) which is being measured by Textechno FAVIMAT instrument and by modern image processing techniques is also been discussed here.
