Embodiment 1

[0023] Embodiment one, such as figure 1 Shown:

[0024] The two ends of the dyed object 8 are wound and tensioned by the active winding roller 9 and the driven winding roller 10, and the dyed object 8 is driven to run. Along the same side of the dyeing process, the extraction nozzle group 1-E, the dye A Dyeing nozzle group 1-D-A, dyeing nozzle group B dyeing nozzle group 1-D-B, dyeing nozzle group C dyeing nozzle group 1-D-C and cleaning nozzle group 1-W, install used fluid recovery device 4 at the corresponding position of each nozzle group, constitute supercritical The single-side spraying process of fluid to the object 8 to be dyed. The supercritical pure fluid pipe 2 connects the extraction nozzle group 1-E and the cleaning nozzle group 1-W with the pure supercritical fluid source; the dye-containing A supercritical fluid pipe 3-A, the dye-containing B supercritical fluid pipe 3-B and the supercritical fluid pipe 3-C containing dye A dyeing nozzle group 1-D-A, dye B dyei...

Embodiment 2

[0034] Embodiment two, such as figure 2 Shown:

[0035] The spraying principle and device flow are the same as those in Embodiment 1, the difference is that the corresponding directions of each nozzle group 1-E~1-W of the device and the respective corresponding used fluid recoverers 4 are alternately installed in the The two sides of the running track of the dyeing process can realize the double-sided spraying and dyeing process of the supercritical fluid on the dyed object 8 .

Embodiment 3

[0036] Embodiment three, such as image 3 Shown:

[0037] Its spraying principle and device flow are the same as those in Embodiment 2, except that each nozzle group 1-E to 1-W of the device and the corresponding used fluid recoverer 4 face the nozzle surface of the dyed object 8 It is made into an arc shape, and the dyed object 8 slides over the surface of the nozzle orifice of each nozzle group 1-E to 1-W when it runs along the track of the dyeing process, and is completed under the guidance and tension of the smooth surface of the nozzle orifice. Dyeing process, so as to realize the self-guiding and tensioning of the dyed object 8, the guide roller 7 in the second embodiment is omitted to achieve the purpose of simplifying the structure, thereby realizing the double-sided spraying process of the supercritical fluid on the dyed object 8.

Abstract

The invention relates to the field of textile dyeing equipment, in particular to a supercritical fluid spray-dyeing device which comprises spray nozzle groups, used fluid collectors, winding rollers and a tensioning component. A driving winding roller and a driven winding roller are respectively installed at two ends of an operation orbit determined by a dyeing process flow in the device and used for winding, supporting and driving objects to be dyed; the spray nozzle groups and the used fluid collectors are respectively installed at two sides of the dying process flow operation orbit according to the order of dying processes and are respectively connected with mechanisms of supercritical fluid generation, dying material dissolution and supercritical fluid medium recycling separation and storage; guide rollers are arranged at the intervals of the all spray nozzle groups or the spray opening surfaces of the all spray nozzle groups are used for supporting and tensioning the object to be dyed; and the spray nozzle groups comprise extracting spray nozzle groups, dyeing spray nozzle groups and cleaning spray nozzle groups. The invention has the advantages of simple structure, convenient and safe operation, low investment, reasonable and advanced flow, good dyeing uniformity and continuity as well as high dyeing quality and productivity.

Description

1. Technical field [0001] The invention relates to the field of textile dyeing equipment, in particular to a supercritical fluid spray dyeing device. 2. Background technology [0002] The processing technology of traditional dyeing equipment has serious problems such as high water consumption, high energy consumption, long process, difficult sewage treatment and high cost. Supercritical fluid dyeing, especially supercritical carbon dioxide dyeing, uses supercritical fluid instead of water as the carrier of the dye to achieve water-free dyeing, thus fundamentally solving the problem of water pollution in the dyeing industry. Supercritical fluid dyeing technology has the advantages of supercritical fluid recycling, no pollution discharge, no drying of dyed objects, less fiber damage, simple and quick operation, high dyeing efficiency and low energy consumption, etc., and has a good development and application prospect. [0003] At present, the supercritical fluid dyeing devic...
