A mathematical model is developed to simulate the rheological behavior of fabric bagging.
The model is based on the assumption that stress-strain relationships in fabric consist of
three essential components: elastic deformation and viscoelastic deformation of fibers and
the friction between fibers and yarns within the fabric structure. The nonlinear strain of the
fabric, the elastic and viscoelastic deformation of fibers, and interfiber friction during the
bagging process have been taken into account in the model. By specifying the fundamental
parameters of fiber mechanical properties and yarn-fabric structural features, the model is
able to predict fabric bagging behavior under test conditions, such as loading and
unloading processes in each cycle, change of bagging force with cycles, relative
contributions of the three components (elasticity, viscoelasticity, and frictional forces) in
each cycle, and residual bagging height in each cycle. A comparison of theoretical
predictions with experimental measurements for two wool fabrics with different structures
reveals good agreement between them. The results indicate that the mathematical model is
able to quantitatively simulate fabric bagging rheological behavior and predict fabric bagging
performance by specifying basic fiber mechanical properties and yarn-fabric structural
parameters.
