Measurement of fabric stiffness by CHES-FY system

The purpose of this paper is to analyze bending stiffness of fabric by the CHES-FY tester,which is compared with the existed methods for bending property of the Cantilever and Heart Loop test.Fabrics with obviously different softnesses and stiffnesses are selected,where the corresponding indexes of the three systems are featured as bending slope,bending work,bending maximum force,bending length and bending height. By analyzing the correlation of the above test results,it is shown that the test result of the softness by CHES-FY system has a strong correlation with the Cantilever and Heart Loop Test. The repeated analysis on the test results shows that the CHES-FY system for fabric softness test has extensive applicability.
