Computed microtomography in the analysis of fiber migration in yarn

This study is a short analysis of the use of computer microphotography in fiber migration testing as a modern nondestructive testing method. Microtomography operates similarly to X-ray computed tomography systems used in medicine, but with much better resolution owing to the use of a smaller radiation spot. The internal structure is reconstructed as a series of two-dimensional cross-sections that are then used to create 2D and 3D morphological objects. This process is non-destructive and does not require special preparation of a testing material.
