Abstract: The now commonly used testing method can test wrinkle resistance of only one direction, which differs greatly from the wrinkles of our clothes. Aiming at this, a new fabric multi-directional wrinkle resistance testing device was designed which can simulate the wrinkles on the knee and elbow. Its testing process was also given, as well as the two evaluation index, ratio of instant and slow wrinkle resistance area. The two index was compared with the instant and slow wrinkle recovery angle of 20 fabrics. The following conclusions could be made: ratio of instant and slow wrinkle resistance area had high correlation with the instant and slow wrinkle recovery angle. As the shape of wrinkles in the new testing method is similar with the wrinkles in our wearing clothes, the new method can reflect the comprehensive wrinkle resistance of fabrics better.
