In this study, fabric bagging tests are performed on a set of knitted fabrics that vary in design, tightness factor, and blend ratio. The relationships between residual bagging height (R residual) obtained from the fabric bagging test and the mechanical characterization determined from the KES-FB system are presented and discussed. The work shows that it is possible to predict R residual for knitted fabrics by using the standard KES-FB test and without performing fabric bagging fatigue tests.
