The KES-F results indicated that the mechanical handle properties of the DMDHEU treated cotton fabrics were affected by both the levels of application of the DMDHEU easy care finishes and the stress relaxation of the fabrics in aqueous conditions.展开更多

The surface change of fabrics before and after abrasion was stu-died by means of scanning electron microscope. With the increasing number of cycles, the re-covery behavior of the fabrics studied in tensile, shear and bending deformation decrease, theantibuckling ability lowers, the friction coefficient increases. The geometric roughness de-creases during the first step of abrasion then enhances with further abrasion. The influence ofabrasion on mechanical properties of the pure wool fabric are larger than that of blend fabric.展开更多

The interaction of each partide is based on a refined mass-spring structure. Regarded the fabric material as an orthotropic continuum, the refinement of our model is focused on the construction of mechanical responses of bending and shearing springs by means of a piecewise polynomial approximation of KES-F testing data. In this way, the draping figure of a silk fabric, a wool fabric and a polyester fabric are simulated. The static final shape and animation of simulation proves that our model has developed an efficient technique on real fabric- drape modeling, and the little computation time of the simulation execution on a PC with Celeron 450 CPU may meet the requirement of real-time simulation.展开更多
