Method for evaluating crease recovery of fabrics based on power function equation

摘要

A method for evaluating crease recovery of fabrics based on power function equation. The steps are: (1) place the sample in the sample placement area; (2) pressure the overlapping part of the sample; (3) let the free part of the sample automatically restore and record the video image of the sample crease recovery by camera; (4) process the video image of the fabric crease recovery and calculating the recovery angle of each frame of video image; (5) repeat steps 1 to 4 to measure N samples of the same fabric; (6) obtain the dynamic process of fabric crease recovery angle change. This can reveal which type of fabric has better recovery property, when the existing methods have the similar results of recovery angle.
