Abstract: To explore more accurate and easy testing and characterization method for fabric’s wrinkle recovery angle, bending, shear, tensile and compression properties of fabrics were tested by KES-FB-AUTO-A System Tester, and two new parameters: residual bending curvature K and residual shear deformationφ, were introduced basing on the original mechanical parameters of KES System Tester. Furthermore, regression equations that warp and weft wrinkle recovery angles were calculated by mechanical parameters were established, respectively. The results indicated that the difference between calculated and tested values of crease recovery angles did not exceed 0.1°. In order to further understand and improve the creasability of fabrics, relationship between fabric’s wrinkle recovery angle and mechanical parameters was analyzed. It was found that tensile recovery percentage, tensile power and bending stiffness had the greatest impact on crease recovery, and fabric anti-crease could be improved by improving stretch resistance, bending resistance, shearing strength and tensile recovery percentage.
