Influence of mechanical and physical properties of fabrics on cutting process

The influence of mechanical and physical properties of fabrics on cutting process and the behaviours of fabrics during automatic cutting of a fabrics lay into garment pieces is studied. It is shown that the blade forces and the mechanical and physical properties of fabrics, such as elongation strength, bending and shear rigidity have significant influences on cutting of fabrics lay. The velocity of vertical and horizontal components of movements of the knife blade, elastic properties of fibres and the air permeability have significant influence on the quality of cutting and pattern pieces, as well.
