Computed tomography application for investigating the internal structure of air-jet yarns
Original language description
The internal arrangement of fibers inside the yarn defines the yarn structure and affects its final properties and performance. Therefore, studying the detailed structure of yarns is one of the important research issues over the years where the depth ofthis study is affected by the available technology at the time. Computed Tomography (CT) is one of the technologies that utilize the interaction of x-rays with a rotated physical object to reconstruct a digital 3D model of the scanned object based on thetransmitted x-rays intensity at different angles. In this study, a low energy x-ray source coupled with high resolution detectors installed in a micro-CT scanner that is capable of imaging objects with a resolution up to 0.3 micrometers. An air-jet spunyarn is introduced in this work with yarn imaging and an algorithm for calculating the packing density of fibers at different slices along the scanned yarn length. The preliminary results of this study show the feasibility of the CT scan
