Continuous dyeing equipment for warp yarns including oxidizing equipment with variable and recoverable capacity

摘要

The present invention relates to a continuous dyeing facility for warp, wherein the dyeing facility includes a plurality of dyeing/pressing groups arranged in a row, and each impregnation or dyeing tank in which the warp is wetted in each dyeing/pressing group is Is provided. The dyeing facility includes an oxidation device comprising a plurality of upper and lower return rollers configured to position the warp yarns on a plurality of vertical planes arranged parallel to each other, and a support frame composed of one or more upper struts and one or more lower struts. . A plurality of upper return rollers are mounted on the upper struts. One or more portions of the lower return rollers are rotatably mounted to one or more respective supporting devices that can be moved in a vertical direction between a first and second operating positions, and in the first operating position, a movable support device Is arranged close to the lower struts to keep the lower return rollers at a predetermined maximum distance from the corresponding upper return rollers, and in the second operating position, the movable support device is arranged close to the upper struts and returns lower The rollers are kept at a predetermined minimum distance from the corresponding upper return rollers.
