长丝集束性的图像法评价及应用OACSTPCD

In view of lacking objective evaluation method for filament fiber bunching performance,the computer vision technology was used to detect it.A method with fiber filling rate and roundness of contour in the cross section to evaluate bundling performance was put forward.The fiber cross section was made by using hot melt adhesive to cover the yarn evenly.And the cross-section image was obtained under the ultra-depth of field microscope.The filling rate and the roundness of the profile of the multi-section cross section of the same yarn were calculated.The bundling performance change was evaluated with normal distribution rule.According to the change of fiber bunching performance under certain friction conditions,the characterization method of abrasion resistance for filaments in weaving process was studied.Objective indexes to evaluate the performance of fiber bundles were provided by the method.It could be used as a supplementary index to evaluate the abrasion resistance of filament.
