The fundamental operations of the weaving process are shedding the warp and inserting the weft to accomplish interlacing of warp with weft. Because shedding happens to be the foremost operation, 3D-weaving process requires dual-directional shedding system (the traditional 2D-weaving process operates with mono-directional shedding system). The dual-directional shedding system alternately displaces the grid-like warp in two directions, column-wise and row-wise, to form corresponding multiple sheds in the two directions. There are two types of dual-directional shedding systems: Linear-Linear shedding and Linear-Angular shedding. The fabric structures produced by these two dual-directional shedding systems are characteristically different. Nandan Khokar, Profiling Performance, Pioneer of 3D-weaving technologies, Biteam
