A water jet cutter, also known as a water jet or waterjet, is an industrial tool capable of cutting fabric lay by using a very high-pressure jet of water, or a mixture of water and an abrasive substance. A very fine water-jet is passed through a nozzle at a very high speed to cut the fabric lay. Water pressure used is 60,000 psi and used to cut fabric, lather, and plastic materials. Thickness of the lay has an influence on cutting quality. Lower the thickness of the lay better will be the cutting quality. Water used for jet needs filtration and de-ionization treatment. Water pressure, nozzle size, and cutting speed are inter-related to cutting quality and speed.
1.Comparatively higher speed of fabric cutting.
2.No need of sharpening/ grinding.
3.Suitable for comparatively harder materials cutting.
1.Not suitable for higher depth of lay cutting;
2.Wet cut edges at the pattern;
3.Water spot may develop in the fabric;
4.Water needs filtration and de-ionization treatment.
5.Lower plies of multi-layer fabric cutting may not have sharp line.
Needs to control sound of water jet.
