Development of image processing based system to study yarn structure during extension

The present study describes design and development and use of an image processing system to characterize and visualize the configuration of fibers in yarn in extended mode. An especially dedicated instrument and software for data acquisition and analysis are the unique features of the system. It is capable of grabbing the images of extended yarn in two orthogonal planes. The software can acquire data from these two orthogonal planes. The three-dimensional trajectory of whole length of different colored tracer fibers can be plotted and can be viewed at different angles. The image processing system along with multi-colored tracer fiber technique has been used for quantitative analysis of changes in the internal structure of ring yarn on extension.
