Abstract
The present invention provides a kind of purplish red dye mixture of dispersion of high colour-fast rate high washing fastness, more particularly to technical field of disperse dyes, it is formed including disperse red, disperse violet and auxiliary agent, disperse red compound shown in formula (I), disperse violet compound shown in formula (II).The present invention provides a kind of existing high washing fastness in the low problem of the dye mixture dye uptake of technology, and has the purplish red dye mixture of the dispersion of high dye uptake.
Description
Technical field
The invention belongs to disperse dyes fields, and in particular to a kind of purplish red dyestuff of dispersion of high colour-fast rate high washing fastness is mixed
Close object.
Background technology
, there is superfine fibre in the development of polyester fiber, due to soft, it is comfortable and easy to wear the features such as, it has also become it is domestic
Outer textile enterprise falls over each other the textile raw material used, with superfine diameter, larger surface area, and the water of general disperse dyes
It washes fastness and dye-uptake is all poor.Ciba disperse purplish red WW-DS (solubility parameter σ=11.69) although washing fastness
Well, but dye-uptake all only has 75% or so, and (solubility parameter of three components is respectively by domestic patent CN102277012A
11.73/11.77/9.29) though dye-uptake has improvement, also only 85% or so, dye uptake is low, it is meant that has more dyestuffs to enter
In sewage, many burdens are increased to environmental protection.
Therefore it is badly in need of a kind of purplish red dye mixture of dispersion for the high colour-fast rate high washing fastness that can solve existing issue.
Invention content
The purpose of the present invention is in the low problem of the dye mixture dye uptake in technology, provide a kind of existing high washing jail
Degree, and have the purplish red dye mixture of the dispersion of high dye uptake.
The present invention provides the following technical solutions：

Preferably, in formula (I), R1And R2It is-CH2COOC2H5Or-CH (CH3)COOCH3。
Preferably, in formula (II), R4 and R5 are-CH2COOC2H5Or-CH (CH3)COOCH3。
Preferably, the auxiliary agent is MF (condensation compound of methyl naphthalene sulfonic acid and formaldehyde) or one kind in sodium lignin sulfonate or two
Kind.
A kind of preparation method of the purplish red dye mixture of dispersion of high colour-fast rate high washing fastness be by formula (I), (II) and
Auxiliary agent mixes in proportion, and water sand is added to grind, and spray drying obtains and disperses purplish red dye mixture.
The purplish red dyestuff of dispersion that the present invention obtains is applied to terylene or dyeing and the stamp of blend.
It is an advantage of the invention that：The purplish red dye mixture of dispersion of the present invention has high dye uptake and high washing fastness.
Specific implementation mode
Embodiment 1
Red-1 200 7.5g, disperse violet 22.5 and auxiliary agent (MF 30g, sodium lignin sulfonate 30g) are weighed by weight simultaneously
It is sanded with together with water, the purplish red dye mixture of dispersion is made in spraying.
Wherein R in formula (I)1=CH2COOC2H5,R2=CH2COOC2H5、
R in formula (II)3=OCH3 R4=CH2COOC2H5,R5=CH2COOC2H5。
Embodiment 2-8
Respectively make embodiment 2-8, production method is same as Example 1, only match and formula (I) in R1And R2
And R3, R4 and R5 in formula (II) change, it is further noted that the then R3 that R3 is not enumerated in table is hydrogen, tool
Body is as shown in table 1：
The structure of 1 embodiment 2-8 of table and specific proportioning
According to a kind of disperse purplish-red dye composition (notification number CN102277012A) of existing patent, disclosed method is prepared
Disperse purplish red dye mixture and compare a group experiment, by embodiment 1-8, the purplish red dye mixture of dispersion that control group obtains respectively takes
1g is scattered in 500ml water, and 20ml dispersion liquids and 80ml water are respectively taken after mixing, and with acetic acid tune PH=4-5, it is super that 2g terylene is added
Fine fibre carries out dyeing processing by national standard GB/T2394-2006 methods, and washing fastness is tested by GB/T3921-2008, and dye uptake is pressed
GB/T9337-2001 is carried out.
Table 2 is the test result (unit of the washing fastness dye-uptake of embodiment 1-8 and control group：Grade)
| Embodiment | 60 DEG C of washing fastness | Dye-uptake |
| 1 | 5 | 94.5% |
| 2 | 5 | 94.5% |
| 3 | 5 | 95% |
| 4 | 5 | 95.5% |
| 5 | 5 | 92.5% |

| Control group | 5 | 86.5% |
Dispersion of the invention is purplish red excellent for Polyester Superfine Fibre Dyeing washing fastness as can be known from the above table, and dye uptake also has
Larger raising, is much higher than comparative example.
Principle：The dyeing course of dyestuff can regard dyestuff course of dissolution on chemical fibre as, and dye-uptake height can be joined with solubility
Number judges, in general, the solubility parameter of dyestuff closer to terylene solubility parameter (σ=10.8, research shows that σ=
Having preferable fastness within 10.8 ± 0.5) dye-uptake is better, and dyestuff is fixed also better on the fabric, this can come from similar compatibility
Understand.Meanwhile parsing can also occur and dyestuff is made to dissociate fabric under the action of dispersant into internal dyestuff,
The fixed capacity variance with parsing determines the height of the dye uptake of dyestuff, in disperse red (I), disperse violet (II) structure, dyestuff
Solubility parameter between 10.3~11.25, than the solubility parameter of Ciba and the closer terylene of patent, especially
The solubility parameter of selected colorant dissolubility parameter (being shown in Table 1) fairly close terylene, the solubility of three components in comparative example
Parameter (red red 376 σ=11.73 in 356 σ=9.29, purple σ=11.77) is then separate, thus the selected compound of this patent all has
Have preferable dye uptake, meanwhile, this patent either formula (I), formula (II) dyestuff dyed with the presence of ester group in structure
During post-treatment caustic wash, it is easy formation-CH2COO or CH (CH3) COO anions, the chlorine of the meta position of azo group has two to inhale electricity
The nitro of son exists, and is easy to form phenol sodium under alkalinity so that fabric surface loose colour forms water-soluble dye, easily washes away, can
To obtain preferable washing fastness, therefore, dispersed black dye mixture of the invention has high dye uptake and high washing fastness.
It these are only the preferred embodiment of the present invention, be not intended to restrict the invention, although with reference to the foregoing embodiments
Invention is explained in detail, for those skilled in the art, still can be to foregoing embodiments institute
The technical solution of record is modified or equivalent replacement of some of the technical features.It is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
