Wrinkling is often considered to be an undesirable visual feature on a garment. To answer the need for a realistic wrinkling measurement method over time, a new method based on image processing was designed. Wrinkled fabrics are scanned over time in a step-by-step manner over two hours. Every wrinkled fabric scan is compared to the flat sample scan using a profile line technique. The resulting curves are analyzed by the mean of a successful regression model. To illustrate the benefits of the proposed method, the influence of the weave pattern on wrinkling is presented.
