A method for hydroenhancing fabrics is described. The method uses the force of pressurized liquid passing through elongated orifices (40) and impinging on the fabric (4). 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.
L'invention porte sur un procédé d'hydro-amélioration de tissus, ce procédé utilisant la force d'un liquide sous pression passant dans des orifices allongés (40) et se précipitant sur le tissu (4). Le liquide sous pression sort de manière cohérente ou sous forme de colonne des orifices allongés qui sont généralement de forme rectangulaire ou linéaire. Les orifices allongés peuvent être disposés de façon à produire divers effets sur une bande de tissu tels que des effets de rayures, de dégradés et seersucker. Les orifices allongés permettent également l'hydro-amélioration de tissus de haute lisse sans effets striés ou moirés. La filtration du liquide sans tension permet d'éviter l'obturation des orifices du fait que les orifices allongés permettent le passage d'objets solides plus gros. L'utilisation des orifices allongés accroît également le rendement énergétique du processus d'hydro-amélioration.
