Crimp is a term to describe the waviness of a fiber. We can also describe this in terms of the force or energy required to uncrimp a fiber. It’s expressed in percentage. A crimped fiber placed on a flat plane is l0 and the length of the same fiber when the crimp is removed by applying a tension is l, then the crimp is given by …

It is an independent method to determine the amount of crystalline matter present in the fiber. W. L. Bragg presented a simple explanation of the diffracted beams from a crystal. When X-ray beam is incident on a crystal, it strongly reflected wherever its layers of atoms at an angle show in fig. Such that, nλ=2dsinθ
