Under the widely used testing method for fabric bending performance, only one result for one direction can be obtained by using one fabric. To investigate a testing method that can characterize fabric multi-directional bending performance simultaneously, 20 common fabrics were chosen and tested with the conventional method to obtain the bending length in the directions of 0°、90°、45°和135° by cutting the fabric sample into stripes along these four directions for testing. Correlation analysis was conducted between projection length and projection area with bending length. It was concluded that both the projection length and projection area have good correlation with bending length of the conventional method, with the coefficient about 0. 95, which proves the new method can be used to characterize the bending properties of 0°、90°、45° and 135°. Two reading can be obtained in each direction, and therefore, it is more efficient and accurate than the conventional method. Besides, it can visualize fabric anisotropy in bending performance and display the testing stability of bending in one direction.
