[0002] A water jet loom is a shuttleless loom that uses a jet of water to draw the weft yarn through the shed. The frictional traction force of water jet weft insertion on the weft yarn is greater than that of air jet weft insertion, and the diffusivity is small, which meets the need for weft insertion of filaments such as synthetic fibers and glass fibers with a smooth surface. At the same time, it can increase the conductivity of synthetic fibers, effectively overcome static electricity in weaving, consume less energy, and have low noise, so it is widely used.
