Surface Roughness Assessment of Woven Fabrics Using Fringe Projection Moiré Techniques
Journal Title: Fibres and Textiles in Eastern Europe - Year 2015, Vol 23, Issue 3
Abstract
In this paper, a new approach is proposed for characterizing the surface roughness of woven fabrics. This approach is based on the fringe projection moiré techniques and analysis of the moiré pattern, which is caused by the interaction between the Ronchi grating and the periodic structure of a woven fabric. In this study, an image processing procedure was employed and a new parameter called the “roughness index” was defined for quantifying the surface roughness. The results obtained from the moiré technique were validated by a set of pair-comparison subjective tests. The proper correlation, with an average R-squared value of 0.9087, between subjective and objective tests confirmed the accuracy, correctness and efficiency of the new method. Statistical analysis of the roughness results clarified that the effect of fabric structural parameters such as the weave structure and weft density is significant in the confidence range of 95%.
