A water-jet is more coherent than an air jet. It is effective in terms of energy requirements and is quiet. When the jet does break up, it goes into droplets which create very little turbulence to disturb the weft yarn. Two main reasons for the efficiency of the water-jet loom are that there are no varying lateral forces to cause the filling to contort, and the moving element is more massive because it is wet. Thus, there is less chance of fault due to contact with the warp.

Water-jet weaving machines were first developed in Czechoslovakia in the 1950s and Subsequently
