Definitions
- the present invention relates to a method for dyeing of a textile substrate in at least one supercritical one Fluid, preferably for dyeing spools of thread in supercritical carbon dioxide, with the characteristics of the generic term of claim 1.
- Textile substrates are still used in practice today colored in the aqueous system, for this purpose each textile substrate to be dyed arranged in an autoclave and there with the watery, at least one Dye-containing liquor flowed through or through becomes.
- this dye liquor is usually used made that a concentrated aqueous dye solution or dye dispersion from the solid dye initially is created using this concentrated dye solution or dye dispersion with that in the autoclave Fleet is successively diluted.
- the direct use of solid dye bypassing the previously described concentrated dye solution or dye dispersion is not possible as this inevitably leads to training of color spots as a result of undissolved or. undispersed Lead dyes on the textile substrate would.
- WO 93/14259 A names light stabilizers for such a substance, Plasticizers, water repellents, Sizing, finishing agents, preparations, flame retardants, pharmaceutical Active ingredients, antistatic agents, anti-pest agents, Bactericides, bacteriostatics, perfumes, adhesives, flavor or fragrances, while DE 42 37 823 A mainly on directed the production of a dye freed from additives with which a corresponding textile Substrate is colored in supercritical fluids.
- the present invention is based on the object Process for dyeing a textile substrate in at least a supercritical fluid of the type specified with which the respective textile substrate to be dyed can be dyed particularly safely and without interference.
- the method according to the invention for dyeing a textile substrate in at least one supercritical fluid preferably for dyeing bobbins in supercritical carbon dioxide before placing the textile substrate in an autoclave and there with the at least one dye flows on or through supercritical fluid.
- the supercritical so mixed with the dispersed dye Fluid is filtered through in the process according to the invention a filter whose pore size is less than or equal to 30 ⁇ m.
- the method according to the invention such a dispersion of the dye in the supercritical Fluid used that has no dye dispersgate or multimolecular dye agglomerates whose size is 30 ⁇ m. This is done, as already stated above is achieved in the method according to the invention in that the supercritical mixed with the dispersed dye Fluid before and / or during staining through a filter filtered, the pore size is less than or equal to 30 microns.
- the method according to the invention has a number of advantages on. It was surprisingly found that incorrect coloring, in particular by the method according to the invention the previously described color spots or uneven Discolorations, which is attributed to that only in the supercritical dyeing liquor multimolecular dye agglomerates the aforementioned maximum particle size available. This also leads to the fact that Process according to the invention with a high reproducibility color loss, i.e. both in terms of color depth as well as the color tone. They are too created using the inventive method Color fastness, especially wet fastness, such as the perspiration fastness, the fastness to rubbing, the water and / or fastness to washing, excellent.
- Another embodiment of the method according to the invention provides that the dye fill with inert particles, especially with glass and / or steel balls, provides so that in this embodiment of the invention Procedure from the outset the risk of clumping of the dye to be dispersed is prevented, since the dye particles to be dispersed are then largely not in contact with each other, but in the gaps, which exist between the inert particles are, which in turn is the previously mentioned Reduction in the dispersing time of the dye to be dispersed is understandable becomes. In addition, the flow conditions uniform.
- the inert particles of the method according to the invention so that their geometric shape and / or their Mass of the geometric shape and / or mass of each used dyes corresponds, so by this measure it is ensured that the fluid flows through none of the dye bed mixed with inert particles Separation of dyes and inert particles brings about.
- a further acceleration of the dispersing process of the at least one dye in the supercritical fluid used in each case is achieved in another embodiment of the process according to the invention by providing granules of the at least one dye in the fluidized bed and / or the fixed bed described above. It was found here that a particularly great acceleration of the dispersing of the at least one dye results in the process according to the invention if granular dye material is selected which has an average particle diameter between 0.5 mm and 5 mm, preferably between 1.5 mm and 3 mm.
- Dye bed opened up as a fluidized bed so can then a particularly reproducible dispersion of the at least a dye or the at least one dye granulate thereby brought about within a very short time be that the dye or the dye granules with a minimal fluidization rate between 0.02 m / s and 0.12 m / s, preferably between 0.04 m / s and 0.06 m / s, swirled in the fluidized bed.
- Another embodiment of the method according to the invention provides that to disperse the at least one Dye forms the bed of dye as such bed, whose axial length is much greater than their radial dimension and that one for dispersing the at least a dye used in supercritical fluid directs axial direction through the bulk material. This leads to an optimized mass transfer and further reduces the dispersion time required in each case.
- Dye fill in particular cylindrical or cylindrical is formed, such a fill of dye from, the axial length of two to ten times, preferably four to seven times larger than their radial dimension.
- Another embodiment of the method according to the invention provides that the at least one to be dispersed Dye in a chambered or channeled one Arranging inert material, whereby the chambers or the channels to the flow direction of the supercritical Fluid aligns that these chambers or channels from the flow through supercritical fluid.
- the dye as a fixed bed in the previously described specially designed inert material so that then when flowing through the chambers or channels at least one dye from the supercritical arranged therein Fluid is dispersed.
- Embodiment of the method according to the invention provides the inert material with honeycomb-like chambers or channels, which enables the greatest possible concentration of the dye to be dispersed on a relative small area can be arranged without this to undesirable clumping or sintering of the material to be dispersed Dye can come.
- Embodiments of the invention have been described above Processes described in which the at least to be dispersed opens up a dye as a bed of dye.
- a fundamentally different solution of the method according to the invention provides that the at least one to be dispersed Dye as a dye melt and / or as a dye dispersion in the supercritical fluid injected so as to disperse the at least previously described produce a dye in the supercritical fluid, this dispersion then the multimolecular dye, but none Contains dye agglomerates, their average particle size is larger than 30 ⁇ m, preferably larger than 15 ⁇ m.
- the ones described below Developments of the method according to the invention are not fixed Dye but a liquid dye with each brought into contact to use supercritical fluid. To ensure that the liquid formulation of each in to achieve the supercritical fluid to be dispersed, there are several options.
- the at least one liquid dye, which as Dye melt is present in the respective by means of a nozzle used supercritical fluid, such allows Working method a particularly precise addition of the required Amount of dye, which in turn is reproducible that according to the inventive method expresses created coloring.
- the inventive method expresses created coloring.
- the amount of dye to be dispersed on the Dispersibility of the supercritical fluid for each used dye via an adjustable time-quantity control vote so that in no time a dispersion of the dye in the supercritical fluid arises.
- this Dispersion then dye agglomerates of a maximum size of less than 30 ⁇ m, preferably of a maximum Has a size of less than 15 ⁇ m, sees further training of the inventive method before that supercritical fluid provided with the dispersed dye filtered through a filter before it is dyed supercritical fluid then with the textile to be dyed Comes into contact with the substrate.
- the dyeing autoclave 1 has a first circulation system provided, the first circulation system corresponding piping system 2 includes. Within this Pipe system 2 of the first circulation system a circulation pump 3 is arranged.
- the piping system 2 has a not shown Feed for carbon dioxide and a heat exchanger (also not shown).
- the in 1 schematically shown a second plant Circulation system, which is designated overall by 11, available.
- valves 4 and 7 of the bypass are opened, so that the supercritical carbon dioxide through the Ink set pot 5 flows and there still listed below Marine dye dispersed. At this time the valve 6 closed.
- the autoclave 12 is filled with a silica gel, type Trysil.
- This silica gel has a particle size between 2 mm and 8 mm, a density of 2,200 kg / m 3 , a bulk density of 550 kg / m 3 , a porosity of 0.55, an inner surface of approx. 450 m 2 / g, a pore volume of 0.4 cm 3 / g, an average pore diameter between 4 nm and 10 nm and a tortuosity factor of 5.0.
- the first embodiment of the Paint batch pot 5 is a fluidized bed paint batch pot 5 formed, this paint approach pot an inner has cylindrical container 10, the top and is closed on the foot side with a sintered metal plate 9, wherein the sintered metal plates 9 are designed as filters and have a maximum pore size of 30 ⁇ m.
- the second embodiment of the paint batch pot shown in FIG. 3 5 has a cylindrical container 15, wherein the cylindrical container 15 at a distance from the inner wall of the paint batch pot 5 is arranged. in this connection the cylindrical container 15 takes the one to be dispersed Dye 13 in the form of a fixed bed.
- the flowing into the cylindrical container 15 supercritical carbon dioxide flows through the inside of the Container 15 arranged as a fixed bed dye 13 radially to the outside, so that the supercritical provided with dye Fluid in the direction of arrow 12 leaves the ink set pot 5.
