Fabric shall be formed by spacing the main and cross wires at a right angle.
When all the main and cross wires are parallel and equally intervals, the mesh forms a square and when the width is different, it becomes rectangular.
Meanwhile, production of plain weave up to the same wire gauge as open mesh is theoretically possible. But use of wire gauge about 80% of open mesh is optimum due to changes in structure at the time of weaving.
The Plain Weave is the most commonly used and simplest wire cloth weave. Each warp wire (wire running-parallel to length of cloth) passes alternately over and under the wires running traversely through the cloth (fill or shoot wires) at 90 degree angles. It has an extremely wide range of applications.
