METHOD FOR HYDROENHANCING FABRICS USING A SHAPED ORIFICE

A method for hydroenhancing fabrics is described. The method uses the force of pressurized liquid passing through elongated orifices and impinging on the fabric. The pressurized liquid exits in a coherent or columnar fashion from elongated orifices that are generally rectangular or linear in shape....

Zusammenfassung:	A method for hydroenhancing fabrics is described. The method uses the force of pressurized liquid passing through elongated orifices and impinging on the fabric. The pressurized liquid exits in a coherent or columnar fashion from elongated orifices that are generally rectangular or linear in shape. The elongated orifices can be arranged so as to produce various effects on a web of fabric, including striping, graduated shading and seer-suckering. The elongated orifices also facilitate the hydroenhancement of high-warp-count fabrics without streak or moire effects. Liquid filtration can be relaxed without clogging the orifices, because the elongated orifices permit larger solid objects to pass. The use of elongated orifices also enhances the energy efficiency of the hydroenhancement process.
