Abstract
The invention discloses a composite anthraquinone-type cobalt blue reactive dye which is prepared by mixing 10-70% of reactive dye A, 10-70% of reactive dye B and 0-80% of assistant, wherein the structural general formulae of A and B are disclosed as (1) and (2). The invention improves the color development and dyeing behavior of the product reactive dye by using the compound densification effect of the two dyes, thereby enhancing the dye-uptake and fixation rate of the dye, improving other application properties of the dye, and especially enhancing the alkaline resistance properties of the dye. The invention implements favorable level-dyeing property, ensures the color consistency before and after pad dyeing, and ensures low red soup tendency in the deep color cold rolling dyeing process. The dye is particularly suitable for dyeing cellulose fibers, protein fibers and polyamide fibers.
Description
Technical field
The present invention relates to a kind ofly be applicable to cellulosic fibre, protein fibre and tynex is contaminated, tie dyeing-gas steams, tie dyeing-bake is banked up and the reactive dyestuffs of the compound anthraquinone type bright blue of jet dyeing with cold rolling.
Background technology
At present the dyestuffs such as Reactive Brilliant Blue KN-R of DYE PRODUCTION manufacturers produce are with a kind of monomeric compound take bromamine acid and vinyl sulfone(RemzaolHuo Xingranliaodehuoxingjituan) sulfate ester aniline as the main raw material preparation.Dyefastness is relatively not high during this dyeing, and particularly lifting force is poor, very easily mutually associates between the dye molecule when dying dark color and hydrolysis generation " red soup " phenomenon.
Summary of the invention
The present invention is directed to the defective that prior art exists, a kind of reactive dyestuffs of compound anthraquinone type bright blue are provided, have high dye uptake and degree of fixation, high levelling property, high enhancing, low substantivity and good detergency particularly have good alkali resistance and broad applicability during dyeing.
The present invention takes following technical scheme for this reason: a kind of compound anthraquinone type bright blue reactive dyestuffs, it is characterized in that being formed by two kinds of active appearance dyestuffs of A, B and auxiliary agent, the mass percent of two kinds of reactive dyestuffs of A, B and auxiliary agent is: dyestuff A accounts for the 10-70% of gross weight, reactive dyestuffs B accounts for the 10-70% of total mass, and auxiliary agent accounts for the 0-80% of total mass;
Dyestuff A, B comprise respectively suc as formula any one or more than one dyestuff shown in (1), (2);
In above-mentioned general formula (1), (2):
M
1, M
2, M
3, M
4Be H, K or Na.
As preferably: in the compound anthraquinone type bright blue reactive dyestuffs of the present invention, dyestuff A is (3) formula:
Dyestuff B is (4) formula:
In the time of necessary, dyestuff can add suitable auxiliary agent and carry out commercialization.Selected auxiliary agent can for: a kind of or its mixture in Sodium sulfate anhydrous.min(99), Sodium hexametaphosphate 99, condensation compound of methyl naphthalene sulfonic acid and formaldehyde, the naphthalene sulfonic acidformaldehyde condensation product is preferably Sodium sulfate anhydrous.min(99).
Active blue dyestuff of the present invention is by the compound synergic technology, utilize two composite hyperchromic effects of dyestuff, dye uptake and the degree of fixation of dyestuff have been improved, improved the alkali resistance of dyestuff, increased the water-soluble of dyestuff, improved by a relatively large margin water-fastness, the fastness to rubbing of dyestuff, improved the quality of products, to satisfy user's needs.Also by to the design of dye molecule two dimensional structure, two dyestuffs are close to cellulosic substantivity and avidity, and two dyestuffs and water base are adsorbed in fiber synchronously.Realize good level-dyeing property, guaranteed the consistence of pad dyeing front and back color and luster.
Embodiment
Embodiment 1
Reactive dyestuffs A's is synthetic:
78.6g bromamine acid, the amino oil of 42.5g (meta-(beta-hydroxyethyl sulfuryl) aniline) and 250g water were 90-95 ℃ of lower making beating 1 hour.Then be cooled to 60-65 ℃, add 45g sodium bicarbonate, under 60-65 ℃, add again 1g copper powder and 2g cuprous chloride, insulation reaction 15 hours, it is terminal point that liquid-phase chromatographic analysis bromamine acid residual quantity≤6% is carried out in sampling.Pour in the 800g water material into making beating 1 hour, carry out acidifying pH value to 1-2 with the sulfuric acid of 40-50%.Stablize pH value 1-2 and carry out suction filtration after lower 30 minutes, filter cake is carried out drying, oven dry under 80-100 ℃, and control moisture≤1%.Shown in color base building-up reactions formula following (5) formula.
The 110g filter cake of oven dry pulverized in the rear vitriol oil that slowly joins 500g 98% carry out esterification, reaction is 15 hours under the normal temperature, it is terminal point that liquid-phase chromatographic analysis color base residual quantity≤1.5% is carried out in sampling, after terminal point arrives, esterifying liquid is diluted in the mixture of ice and water of 1000g ice and 1500g water temperature in the dilution≤25 ℃, diluting complete rear adding 120g sodium-chlor saltouts, suction filtration adds in the 500g water making beating 1 hour with filter cake, and is neutralized to pH value 5-7 with 80g sodium bicarbonate.And dry materials become the particulate state dyestuff, get blue dry product 198.3g.
Shown in dyestuff building-up reactions formula following (6) formula.
Reactive dyestuffs B's is synthetic:
85.5g bromamine acid and 102.7g para-ester (to (beta-sulfuric ester ethyl sulfonyl) aniline) and 300g water were 40-45 ℃ of lower making beating 1 hour.Add 50g sodium bicarbonate, 1.5g copper powder and 5g cuprous chloride, insulation reaction 20 hours, it is terminal point that liquid-phase chromatographic analysis bromamine acid residual quantity≤5.5% is carried out in sampling.Pour in the 1000g water material into making beating 1 hour, the hydrochloric acid with 10-30% carries out acidifying pH value to 1-2 again.Add 150g sodium-chlor and saltout, filter cake is joined in the 500g water pull an oar, and with in the 70.6g sodium bicarbonate with the pH value to 5-7.And dry materials become the particulate state dyestuff, get blue dry product 178.6g.
