Definitions

  • the dyeing of textile material from cellulose fibers by pulling out alkaline fixing reactive dyes from an aqueous medium is by far the largest and most important area of application for this class of dyes and, according to the previous procedures, usually takes place in the "all-in process” or in a “preliminary process” or in a “stage process", which differ from one another in terms of the type of process management. This takes into account the fact that there is a very high risk of irregularity if, in the case of a reactive dyeing of the dye and electrolyte-containing liquor at dyeing temperature, all of the alkali required for fixing is available at once, which results in a rapid increase in the fixing of the dye.
  • the entire amount of dye, salt, alkali and, if appropriate, a textile auxiliary at low temperature (room temperature) is put into the pull-out bath in the usual "all-in process" fed dyeing machine loaded with textile goods; thereupon the batch prepared in this way is heated to the intended dyeing temperature and the measures introduced for coloring the goods are now brought to a end for a certain time under the set temperature conditions, the fixing taking place.
  • fast-fixing dyes are often used to achieve insufficient levelness of coloration in the presence of otherwise difficult material and / or machine conditions.
  • an isothermal dyeing process is known from ZA-A-84/1967 and is used in practice, according to which, at dyeing temperature, an aqueous dye bath containing the dye, electrolyte, optionally a textile auxiliary and the cellulosic textile material is used continuously to fix the Reactive dye required alkali is metered.
  • the alkali is dosed automatically; it starts with a small amount of alkali per unit of time, and this addition of alkali is increasingly increased in the course of the metering process in accordance with a specific program.
  • the progression of metering can be controlled between 0% (linear) and 100% (exponential or logarithmic) in 10% steps.
  • the dosing time can be 30, 60 or 90 minutes.
  • the procedure described above is carried out automatically with the aid of a computer-controlled metering device (e.g. from the prototype shown in ZA-A-84/1967), which is capable due to its design features, the alkali metering into the fleet immediately under fixing conditions according to the prescribed Control addition scheme.
  • a computer-controlled metering device e.g. from the prototype shown in ZA-A-84/1967
  • the addition of the fixing alkali to the alkali-free dye bath can be carried out at a constant temperature be made in the range of 30-100 ° C; but there is also the possibility that the temperature is increased or decreased during the actual metering process.
  • the isothermal procedure is preferred, with a relatively low temperature (range around 30-50 ° C.) or a relatively high temperature (range around 60-100 ° C.) being selected, depending on the type of dye or substrate.
  • the precautions according to the invention for the continuous or approximately continuous control of the addition mode based on the dimensioning of a parabolic function can also be understood in such a way that within the scope of the dosing process, the addition of a first rate corresponding to 1/15 to 1/400, preferably 1/15 to 1 / 73, the total amount of alkali required for dye fixation begins that the addition rate decreases in quantity after 20 minutes at the latest and then continues to increase in volume from then on in accordance with the expiration of the time required for the alkali addition of the pull-out phase finally reached the maximum value.
  • the one for the special The guidelines to be applied for programming the amount of alkali to be added per unit of time depend on the type of reactive dye or its reactive anchor, the type of textile material and the type of dyeing equipment used (for stationary or moving goods).
  • the characteristic of the dosing curve symbolized by a diagram (depending on progression and time) can have a relatively flat or relatively steep curve.
  • the total metering process can generally be completed in a time between 10 and 120 minutes, preferably between 15 and 60 minutes, which makes up a substantial part of the total dyeing time.
  • a step-by-step alkali metering is to be understood as a mode of operation in which the mode of addition for the alkali amounts over the entire metering period follows the course of a parabola, but in which the measures for metering take place in individual batches (e.g. analogous to the rhythm of a piston pump) or at that the rate of addition remains constant for a certain time (seconds or minutes) and then gradually changes to reduced or increased values.
  • the alkali metering according to the invention can thus also proceed in such a way that certain constant units of quantity of the alkali are metered in at such a time cycle that the course of a parabola is observed over the entire metering period.
  • the alkali to be used for dye fixation according to the process can be an alkali hydroxide, carbonate, bicarbonate, phosphate, metaphosphate, pyrophosphate, polyphosphate or another alkaline substance or also a mixture of various of these alkalis, in particular the corresponding sodium compounds.
  • the needed amount and selection of such alkalis depends on the type of reactive dye used or its reactive anchor and corresponds to the recipes customary in dyeing practice.
  • the process according to the invention leads to a surprisingly cheap, i.e. even course of dye fixation. This means that the dyeing process can be completed in a much shorter time than was possible according to the prior art and that one can still achieve excellent dye levelness.
  • the organic dyes known under this generic term - regardless of the type of their fiber-reactive group - are considered as reactive dyes.
  • This class of dyes is referred to in the Color Index, 3rd edition 1971 and additions in 1975 as "C.I. Reactive Dyes” and comprises chemical compounds with a dye character which are able to form a covalent bond with fibers containing OH groups. These are predominantly those dyes which contain at least one group which is reactive with polyhydroxyl fibers, a precursor therefor or a substituent which is reactive with the polyhydroxyl fiber.
  • Particularly suitable as the base of the chromophoric system of these organic dyes are those from the series of the azo, anthraquinone and phthalocyanine compounds, it being possible for the azo and phthalocyanine dyes to be both metal-free and metal-containing.
  • reactive groups and precursors which form such reactive groups include epoxy groups, the ethyleneimide group, the vinyl grouping in the vinylsulfone or acrylic acid residue, also the ⁇ -sulfatoethylsulfone group, the ⁇ -chloroethylsulfone group or the ⁇ -dialkylamino-ethylsulfone group.
  • Derivatives of the tetrafluorocyclobutyl series, for example tetrafluorocyclobutyl acrylic acid, are also suitable for this process.
  • the reactive substituents in reactive dyes are those that are easily removable and leave an electrophilic residue.
  • halogen atoms on the following ring systems are of interest as substituents: quinoxaline, triazine, pyrimidine, phthalazine, pyridazine and pyridazone.
  • Dyes with several identical or different types of reactive groups can also be used, as can combinations of dyes of the same or different types.
  • Such reactive dyes of the type defined above often have more than one sulfonic acid group (apart from that in the reactive group of the dye) in the molecule, which can be distributed as desired over the chromophore, but are preferably bound to its aromatic radicals.
  • Dyes of the vinyl sulfone type are preferably used for carrying out the claimed process, with which the fiber reacts via an addition mechanism via the vinyl sulfone form of the dye and which have either the vinyl sulfone residue itself or the ⁇ -sulfatoethyl sulfone group as reactive anchors.
  • coloring substances are those dyes which, in addition to a reactive residue of the vinylsulfone type or precursor thereof, additionally have at least one group which reacts with the cellulose according to the substitution mechanism, e.g. a monochlorotriazinyl or monofluorotriazinyl group.
  • cellulose fibers to be dyed according to the invention are cotton, mercerized or leached cotton, conventional regenerated cellulose fibers, (R) modal fibers and other vegetable fibers, such as flat to understand.
  • the process according to the invention is suitable for mixtures of the abovementioned fibers with one another and with other fibers, such as, for example, polyester, polyamide, polyacrylonitrile fibers or silk.
  • the dyeing itself can be in the various processing stages or presentation forms of the textile material, such as As a flake, as a sliver, as a yarn, as a fabric, as a knitted fabric or as a fleece.
