Definitions
- the invention relates to a composition which is suitable as a dyeing aid, a process for their preparation and their use in the dyeing of fibers.
- chromophore degradation is usually associated with color change, unegalality and Reproduction problems as well as with color fastness impairments that more or less can be pronounced.
- Particularly sensitive to such interference are azo dyes and many basic dyes.
- azo dyes a (partial) Cleavage of the azo group in amino groups and thus chromophore cleavage with the Consequence of a hypo- and hypsochromic color shift.
- cellulose reactive dyeings dieings of Cotton fibers, bast fibers (such as linen, flax, hemp, jute, etc.) regenerated cellulose fibers (such as Viscose, Modal, Polynosic, Lyocell, Cupro, etc.), HT (high temperature) stains of PES (polyesters) and their blends, and in general PAN (polyacrylonitrile) dyeings sensitive.
- the regenerated fibers are more critical than native fibers, in the PES stains those in the alkaline pH range more endangered than those in the acid.
- NTA alkaline earth metal iodate NTA solutions
- the solid, usually granulated Na-m-nitrobenzenesulfonates create dosing problems that exhibit liquid alternatives a relatively weak effect, since their concentration is 20-25% due to their solubility is limited. Even at this concentration crystallization occurs over time, so that the stability is questionable.
- AOX adsorbable organic halogen compounds
- at Reactive dyes can reduce the oxidation potential of the products, at least when hot-dyeing, already be critical and contribute to a chromophore destruction. The same applies to their Application at PES.
- the present invention is therefore based on the object, a composition that as Dyeing aid can be used to provide, with the above reduced colouration phenomena of dyes during dyeing or largely avoided, without the disadvantages of the prior art have previously used compositions.
- composition of the invention may conveniently be aqueous Act solution.
- the aromatic nitro compound and the phosphonate are dissolved in water.
- composition of the invention can be in the Composition of the invention not only a qualitative but also a quantitative Synergism, since even at very low concentrations of the two individual Active ingredients in the composition according to the invention are still significant known, normal-concentrated products comparable effects in terms of dye protection possible are.
- the use of the composition according to the invention means for the Users thus with dyeing increased operational safety with minimal cost.
- the universality of the composition of the invention in terms of Dye and dyeing method particularly advantageous, i. the invention Composition can be found in a variety of different dyes and in many different dyeing methods are used.
- Composition can be appropriate blends quickly and inexpensively to produce. Crystallization of the aromatic nitro compound and / or the Phosphonate was not detected, this has a positive effect on the storage and service properties and the effectiveness of the composition of the invention.
- composition of the invention may be several, different from each other contain organic nitro compounds. It can also be several, from each other have different phosphonates.
- composition according to the invention is organic nitro compound a nitrobenzenesulfonic acid alkali metal salt, preferably sodium m-nitrobenzenesulfonate, or a mixture of several, different from each other Nitrobenzenesulfonic acid alkali metal salts, preferably a mixture of about 90% sodium m-nitrobenzenesulfonate, about 5% sodium o-nitrobenzenesulfonate and about 5% sodium p-nitrobenzenesulfonate.
- Nitrobenzenesulfonates have changed their activity Composition according to the invention as a dyeing auxiliaries, in particular for reducing of coking phenomena of dyes during dyeing, as particularly favorable proved.
- the above-described advantages of the invention Composition by these preferred aromatic nitro compounds in particular obtained in a favorable manner.
- R 3 is CH 3 .
- the use of this phosphonate has proven to be particularly favorable, since the composition according to the invention is particularly effective as dyeing auxiliaries, in particular for reducing or as far as possible preventing the coking phenomena of dyes during dyeing. Furthermore, the above-described advantages of the composition of the invention with this preferred phosphonate are achieved in a particularly favorable manner.
- the composition according to the invention can be used in Form of an aqueous solution, wherein water serves as a solvent and therein the aromatic nitro compound and the phosphonate are dissolved.
- the inventive composition then a pH of 6.0 to 7.5, in particular about 6,7, up.
- the adjustment of the pH value to these preferred values takes place, depending on Initial pH, by adding an acid or base, which in the latter case ammonia has proved to be particularly favorable. It can be used in the form of an aqueous solution become. As a result, ammonium ions present in the aromatic nitro compound and the Phosphonate can be introduced.
- composition according to the invention can be deprotonated, e.g. in the above-described pH adjustment, or the salts in the inventive Composition in dissociated form, if e.g. the aromatic nitro compound and / or the phosphonate are each used as a salt.
- the invention further provides a process for the preparation of the invention Composition in which the aromatic nitro compound, as described above and the phosphonate, as also described above, in water be solved.
- the composition of the invention in received in a simpler, faster and cheaper way.
- hydroxyethane diphosphonic acid may be mixed with lye, preferably with Ammonia (hydroxyethanediphosphonic acid ammonium salt) in a mixing ratio of 65-85: 35-15, preferably about 75:25, are used.
- This mixture can be with 1.8 wt.% To 10 %
- Ammonia are used in the composition of the invention.
- Hydroxyethanediphosphonic acid can in this case in 40% to 65%, preferably about 60%, aqueous solution can be used.
- Ammonia may be present in 10% to 25%, preferably in about 25% aqueous solution can be used.
- acidic and basic Components of the mixture may have a pH of from 6.0 to 7.5, preferably about 6.7
- the composition of the invention can be adjusted.
- the invention is suitable Composition very well as dyeing auxiliaries, in particular for the reduction of Caking and precipitation phenomena of dyes during dyeing.
- the composition according to the invention in amounts of 0.5 g / l to 10 g / l, preferably 1.5-3 g / l in batch processes (exhaust process) and 3-5 g / l in continuous process (padding or padding).
- the liquor is heated to 50 ° C with maximum gradient and there 2.0 parts of Composition according to Example 1, 1.5 parts of a leveling carrier on Base of emulsified alkyl benzoate, 1.0 part of a liquid dispersant based on Alkylbenzenesulfonate and Napthalinmethansulfonat polycondensate and 1.0 parts of sodium acetate added.
- the pH is then adjusted to 4.5 with acetic acid (60%) and after another 10 min. at 50 ° C the dye added:
- 100 parts of a cotton raw yarn in Buchspulapparat Turbostat 1 VZ is with a liquor containing 0.1 part of a deaerator based on emulsified polysiloxane with Hydroxyethanolan turnover, 2.0 parts of a multi-functional product for raw cotton dyeing, consisting of a specific formulation of polyacrylates, polyacrylamides, Sulfosuccinates, ethoxylates and solubilizers and 3.0 parts of the invention Composition according to Example 1 with 950 parts of water at 40 ° C with 2 ° dH, added.
- This application gives a yarn that respects color fidelity, levelness and Authenticity an and the result of a coloration on conservatively pretreated, i. alkaline or sour boiled goods accordingly.

Abstract
Description
- semikontinuierliche Pad-Roll-Färbung von Cellulosefasern mit reduktionsmittelempfindlichen Substantivfarbstoffen, und
- diskontinuierliche und kontinuierliche (Pad-Steam) Reaktivfärbung von Cellulosefasern;
- diskontinuierliche Reaktivfärbung von Cel ist insbesondere wiederum die Heißfärbung, d.h. die Fixierung bei Temperaturen größer gleich 70 °C relevant (insbesondere ist dies für mittel- bis wenigreaktante Reaktivfarbstoffe, "Heißfärber", vorzugsweise auf Monochlortriazin-Basis der Fall), besonders kritisch sind hier bekanntermaßen Zelluloseregeneratfasern;
- diskontinuierliche PES-HT-Färbung, im Sauren und noch mehr im Alkalischen, insbesondere bei Verwendung von Azo-Dispersfarbstoffen;
- diskontinuierliche und kontinuierliche Färbung von PAN und dessen Mischungen, insbesondere mit Cellulosefasern mit reduktionsmittelempfindlichen basischen (kationischen) Farbstoffen.
wird nach Passage einer IR-Aufheizzone in der Pad-Roll-Kammer in gesättigter Dampfatmosphäre bei 80°C vier Stunden rollierend verweilt.
