Definitions

  • the present invention relates to a method for dyeing from supercritical CO2.
  • the object of the present invention was to improve this known method. This object is achieved by the method according to the invention.
  • the present invention thus relates to a process for dyeing hydrophobic textile material with disperse dyes by heating the textile material and the disperse dye in supercritical carbon dioxide at a pressure of 73 to 400 bar to a temperature of 80 to 300 ° C and then the pressure and the temperature lowered to below the critical pressure and the critical temperature, characterized in that the pressure reduction is carried out in several stages and the pressure in each stage is reduced by 0.1 to 20 bar and after each stage is waited until a practically constant pressure has stopped.
  • the dyeing of textile substrates from supercritical CO2 has a number of advantages over dyeing processes from an aqueous liquor. Due to the fact that the CO2 used does not get into the wastewater, but is preferably used again after dyeing, no wastewater pollution occurs. Furthermore, the dyeing of supercritical CO2 required for dyeing the textile substrate Mass transfer processes take place much faster compared to aqueous systems. This in turn means that the textile substrate to be dyed can be flowed through particularly well and quickly. When using dyeing from supercritical CO2, there are no irregularities with regard to the flow through the winding body during the coloring of winding bodies, which are to be regarded as causes for edge runs or length runs, for example, in the conventional method for tree coloring of flat structures.
  • no disperse dyes can undesirably agglomerate, as is sometimes the case with conventional dispersion dyeings, so that the use of dyeing from supercritical CO2 avoids the brightening of disperse dyes known in conventional dyeing processes in aqueous systems, and thus the formation of corresponding stains.
  • Another advantage of dyeing from supercritical CO2 is that you can use disperse dyes that consist exclusively of the actual dye and do not contain the usual dispersants and agents. For many dyes, there is also no need to grind the dyes.
  • supercritical CO2 means CO2 in which the pressure and the temperature of the CO2 are above the critical pressure and the critical temperature.
  • the supercritical CO2 has approximately the viscosity of the corresponding gas and a density that is approximately comparable with the density of the correspondingly liquefied gas.
  • the dyeing process according to the invention is carried out, for example, in such a way that the textile material to be dyed is placed together with the disperse dye in a pressure-resistant dyeing apparatus and heated to the dyeing temperature under CO2 pressure or by heating and then adjusting the desired CO2 pressure.
  • the dyeing temperature used in the process according to the invention depends essentially on the substrate to be dyed. Usually it is between about 80 and 300 ° C, preferably between about 100 and 150 ° C.
  • the pressure to be applied must be at least so high that the CO2 is in a supercritical state. The higher the pressure, the greater the solubility of the dyes in CO2 in general, but the greater the expenditure on equipment.
  • the pressure is preferably between about 73 and 400 bar, in particular between about 150 and 250 bar. At the preferred dyeing temperature for polyester material of approximately 130 ° C., the pressure is approximately 200 bar.
  • the liquor ratio (mass ratio of textile material: CO2) when dyeing by the process according to the invention depends on the goods to be treated and their presentation.
  • polyester yarns which are wound onto corresponding packages are to be dyed using the process according to the invention, this is preferably done with relatively short liquor ratios, i.e. Fleet ratios between 1: 2 to 1: 5.
  • Such short liquor ratios generally cause difficulties in the conventional dyeing process in the aqueous system, since there is often the risk that the finely dispersed systems agglomerate due to the high dye concentration. However, this does not occur in the method according to the invention.
  • the desired pressure is set, if this has not already been reached due to the temperature increase.
  • the temperature and pressure are then kept for some time, e.g. Kept constant for 1 to 60 minutes, taking suitable measures, e.g. Stirring or shaking, or above all by circulation of the "dye liquor" ensures intensive mixing of the textile material and "dye liquor".
  • the length of time is generally not critical, but it has been shown that times of more than 10 minutes usually do not improve the dyeing yield.
  • the pressure is then reduced in several stages, preferably in 2 to 100 stages, which is done most simply by opening a valve and releasing a portion of CO2.
  • the rapid expansion results in cooling, that is, it is quasi-adiabatically expanded.
  • the density of the CO2 is changed by lowering the pressure. After closing the valve, heating to the Ambient temperature instead, the pressure rises isochorically again. After approx. 30 seconds to a few minutes, when the pressure and temperature practically no longer rise, the pressure is reduced again and the process described above is repeated.
  • This mode of operation is preferably controlled automatically by a pressure and / or density and / or temperature program.
  • the pressure in each stage is preferably reduced by 1 to 10 bar and especially by 2 to 5 bar.
  • the textile material is then removed from the dyeing machine and can often be used without further cleaning. In particular, it should be noted that no drying is required.
  • the CO2 can then be collected and used again after coloring to the supercritical state for the coloring of other substrates.
  • the dyes separate out as liquid or solid dyes, which can be collected accordingly and used for further dyeings.
  • the method according to the invention is suitable for dyeing semi-synthetic and in particular synthetic hydrophobic fiber materials, especially textile materials.
  • Textile materials from blended fabrics which contain such semi-synthetic or synthetic hydrophobic textile materials can also be dyed by the process according to the invention.
  • Cellulose-21 ⁇ 2-acetate and cellulose triacetate are particularly suitable as semi-synthetic textile materials.
  • Synthetic hydrophobic textile materials consist primarily of linear, aromatic polyesters, for example those made of terephthalic acid and glycols, especially ethylene glycol or condensation products made of terephthalic acid and 1,4-bis (hydroxymethyl) cyclohexane; from polycarbonates, e.g. from ⁇ , ⁇ -dimethyl-4,4'-dihydroxy-diphenylmethane and phosgene, from fibers based on polyvinyl chloride, polypropylene or polyamide, e.g. Polyamide 6.6, polamide 6.10, polyamide 6, polyamide 11 or poly (1,4-phenylene terephthalamide).
  • Microfilament fibers made of polyester e.g. Color polyethylene terephthalate with very good levelness.
  • Suitable dyes for the process according to the invention are, above all, dispersion dyes, i.e. dyes which are sparingly soluble or almost insoluble in water.
  • dyes from the following classes are possible: Nitro dyes, for example nitrodiphenylamine dyes, methine dyes, quinoline dyes, amino naphthoquinone dyes, coumarin dyes and in particular anthraquinone dyes, tricyanovinyl dyes and azo dyes such as monoazo and disazo dyes.
  • Nitro dyes for example nitrodiphenylamine dyes, methine dyes, quinoline dyes, amino naphthoquinone dyes, coumarin dyes and in particular anthraquinone dyes, tricyanovinyl dyes and azo dyes such as monoazo and disazo dyes.
  • a strip of polyester fabric and 1.5% by weight, based on the polyester fabric, of the dye of the formula are placed in an autoclave
  • the autoclave is flushed with CO2 gas and heated to 130 ° C under 10 bar CO2 pressure at a heating rate of 2 ° C per minute, the stirrer running at approx. 100 revolutions per minute. Then the pressure is increased to 250 bar within 1.5 to 2.5 minutes and the stirrer speed is increased to about 700 revolutions per minute.
  • the pressure is reduced by 5 bar within 5 to 15 seconds by releasing CO2, the temperature in the autoclave falling by about 2 ° C. After closing the valve, the pressure rises again by about 2 bar within the next minute and the temperature returns to the original value.
  • the pressure is again reduced by 7 bar within 5 to 15 seconds by releasing CO2, the valve is closed and the system waits for 1 minute to set a constant temperature and pressure. This process is repeated until the pressure has dropped to 180 bar. (approx. 15 minutes) The residual pressure in the autoclave is then released and the polyester fabric is removed from the hot autoclave.
  • a red-dyed polyester fabric of similar quality to that obtained by dyeing by customary methods from an aqueous liquor is obtained.
  • Example 1 If one works as described in Example 1, but after reaching 130 ° C. and a pressure of 250 bar and a stirrer speed of 700 revolutions per minute, these conditions are kept constant for 25 minutes, then the pressure in the autoclave is released within 30 seconds, cools and removes the dyed polyester fabric, the color depth is only approx. 1 10th the color depth obtained in Example 1.
