Abstract: Aiming at the deficiency that the static measurement method just can measure fabric wrinkle recovery angle at some moment, this paper presents a novel method to measure the wrinkle recovery angle by video sequence. The SDL-M003 loading device is used to press a sample according to AATCC 66-2008. Then place the folded sample in the video sequence system and record a 5 min video of the recovery period. Each video frame is processed sequently by thinning algorithm and Hough transform to get the wrinkle recovery angle. The test results of the video sequence method and the AATCC 66-2008 test method are close to each other, which indicate that our new method is feasible. The obtained angles of the 5 min recovery period provide more information to determine wrinkle recovery behaviors of fabrics, as well as lay a foundation for the proposal of new wrinkle evaluation criteria.
