ABSTRACT:
The procedure consists essentially of causing the corded fabric (4) to circulate in a continuous manner through a bath (3) of treatment liquid, and is characterized by the fact that the fabric (4) is subjected simultaneously to injection and spraying of the treatment bath liquid (3), by means of mixing air with the liquid, which separates into microparticles, the intake of the bath being effected from different points and at low pressure. The device comprises a substantially circular chamber (1), means (5) for the pulling of the fabric, with the fabric (4) circulating through a passageway defined between an outer plate (6) located next to the wall of the chamber (2) and an inner plate (7), and is characterized by the fact that it comprises a plurality of points (9, 10, 11, 12) of injection and spraying of the bath liquid along the entire run of the fabric (4) in the chamber (1). The plates (6, 7) form a spout (8) which facilitates the movement of the fabric ( 4). It also includes a grid (13) which permits better draining of the fabric (4). The dye is applied in a homogeneous manner.
