    • An oxidation intensifier device for a continuous dyeing system for dyeing a warp thread, the device arranged for being mounted in the oxidation assembly of the dyeing system and comprises two blowing assemblies having a substantially identical shape and opposed one another, each blowing assembly is provided with at least one respective fan and, downstream of such a fan, with a respective plurality of convergent conduits arranged along development directions that are parallel and transversal to the feeding direction of the warp thread, the convergent conduits of a first blowing assembly converge in a opposite direction with respect to the convergence direction of the convergent conduits of the opposite blowing assembly, each convergent conduit is configured to face parallel to a single lap of the warp thread moving inside the dyeing system and is provided with a plurality of longitudinal slots oriented along the same development direction of the respective convergent conduit, where each fan is hydraulically connected to the plurality of convergent conduits of the respective blowing assembly and is configured to convey air towards the plurality of longitudinal slots, so that a plurality of opposite air laminar flows is generated, which generate a plurality of turbulences adapted to facilitate the oxidation process of the dyed warp thread on both its surfaces.
