<p>A flexible irrigation hose. The hose (1 ) comprises an inner layer (2) in a first thermoplastic polymer material, an outer layer (3) in a second thermoplastic polymer material, a first textile reinforcement layer (4) and a second textile reinforcement layer (5) in overlapped reciprocal relation. The first and second textile reinforcement layers (4, 5) are knitted together with chain stitches (6, 6') of the tricot type having rows (7, 7') and courses (8, 8'). The courses (8, 8') of said first and second textile layer (4, 5) have inclinations (a, ß) opposite to one another with respect to the longitudinal axis (X) of the hose, and in that the rows (7, 7') of at least one between said first and said second textile layers (4, 5) are substantially parallel to said longitudinal axis (X). A method of manufacturing such hose, a line (10) for the production thereof and a knitting machine (20) for manufacturing such hose.</p> |
