Water-Jet Weaving Machinery
category
Water-jet weaving machines insert weft yarn using a high-velocity water jet from a pump-nozzle system, carrying the weft yarn hydraulically across the shed at insertion rates of 800 to 1600 metres per minute for hydrophobic synthetic filament yarns including polyester, nylon, and glass fibre that are not damaged by water contact and can be inserted more economically than with air-jet due to lower energy costs.
Role
Provides the most energy-efficient shuttleless insertion method for hydrophobic synthetic filament fabrics including polyester and nylon taffeta, lining fabrics, glass fibre technical fabrics, and industrial filtration fabrics where the water carrier medium is compatible with the yarn and subsequent fabric wet processing, with operating cost advantages over air-jet driving water-jet adoption in these specific fabric segments.
