Abstract

An oxidation intensifier apparatus for continuous warp-chain indigo dyeing machines for dyeing a plurality of adjacent spaced parallel warp threads passing in a traveling path through a plurality of dyeing and squeezing units includes a first oxidation intensifier unit (10A) on one side of said traveling path, a second oxidation intensifier unit on the other side of said traveling path between two dyeing and squeezing units (I and II), and a fan (19) in each unit for blowing air onto opposite sides of the warp threads passing between the units. Each oxidation intensifier unit has an inlet on which the fan (19) is mounted, a diffuser (22) having an air inlet (21) adjacent the output side (20) of the fan and a diffuser outlet (23) in adjacent spaced relationship to the traveling warp threads (12). Each diffuser may contain in its interior a deflector (25) and/or a grille-type conveyor (26) to assure uniform distribution of the air delivered from the fan to the traveling warp threads. The outlet end of the diffuser (23) may have mounted thereon a perforated plate to further assure uniform distribution of air from the fan onto the warp threads. The diffuser extends over the entire width of the traveling warp threads and may be provided with a plurality of equally spaced fans across the width of the diffuser.
