Water-Jet Loom Technology and Operation
category
Water-jet looms insert weft yarn by propelling it through the shed using a high-velocity water jet from a pump-nozzle system, achieving insertion velocities similar to air-jet at 400 to 800 picks per minute across fabric widths of 150 to 330 centimetres, with the water acting as both carrier and lubricant for the yarn during insertion, making water-jet weaving particularly suitable for synthetic filament yarns including polyester, nylon, and glass fibre that are not absorbent and can be dried efficiently after the wet insertion process.
Role
Provides a specific shuttleless weaving technology for synthetic filament fabric production where the water insertion medium provides better yarn control than air-jet for certain filament yarn types and the lower noise of water-jet operation compared to air-jet is an operational advantage, with water-jet weaving being concentrated in Japan, South Korea, and Taiwan for synthetic fabric production where the technology has retained a significant market position in the polyester and nylon filament fabric sector.
