Abstract
The present invention provides a kind of orange disperse dye mixture of high washing fastness, belongs to technical field of disperse dyes, is made of dyestuff A, dyestuff B and auxiliary agent, and dyestuff A is compound shown in formula (I), and dyestuff B is compound shown in formula (II).The present invention problem low for washing fastness existing for orange in the prior art, provides that a kind of preparation process is simple, the higher orange disperse dye mixture of washing fastness, can preferably promote dyeing and the printing quality of dacron.
Description
Technical field
The invention belongs to technical field of disperse dyes, and in particular to a kind of orange disperse dye mixing of high washing fastness
Object.
Background technique
In dyestuff used at present, there is a problem of dyefastness difference mostly, especially washing fastness is up to less than 4 grades.
The reason for causing washing fastness low mainly includes two aspects, is on the one hand always to have some dyes not in the dyeing course of dyestuff
It can enter the inside of fabric and surface can only be adsorbed on, the dyestuff on surface is referred to as loose colour, and the processing of these loose colours is not done
Only, other fabric staining are easily led in subsequent laundering process, even if being on the other hand that a small amount of dyestuff has entered inside dyestuff,
Under detergent and temperature action, dyestuff can also be drawn out and be adsorbed on fabric surface.
The fastness of dyestuff can be judged with solubility parameter σ, and for dacron, the solubility parameter of dyestuff is closer
The solubility parameter of terylene, fastness are better.Orange dyestuff is formed by Br-19 and Y-246 blending in the market, Br-19 and Y-246
Respectively compound shown in following formula (III) and (IV).
Although there is ester group in Br-19 structure, there is hydroxyl in Y-246 structure, after dyeing in alkali cleaning treatment process, ester group holds
Easy formation-CH2CH2COONa, hydroxyl easily form phenol sodium and easily wash away, but fixed fastness is bad, because of the solubility parameter σ of terylene
=10.8, there is preferable fastness, and the solubility of Br-19, Y-246 when within solubility parameter σ=10.8 ± 0.5 of dyestuff
Parameter is respectively 10.09 and 12.78, larger with the gap of solubility parameter σ=10.8 of terylene, in washing process, is easy quilt
Detergent extracts and declines washing fastness.
Therefore it is badly in need of a kind of orange disperse dye mixture of high washing fastness for being able to solve existing issue.
Summary of the invention
The purpose of the present invention is aiming at the problem that dyes poor color fastness in the prior art, provide a kind of preparation process letter
Single, high washing fastness orange disperse dye mixture.
The present invention provides the following technical solutions:
A kind of orange disperse dye mixture of high washing fastness, is made of dyestuff A, dyestuff B and auxiliary agent；
The dyestuff A is compound shown in following formula (I):
Wherein, R1For CH2COOC2H5、CH2COOCH2COCH3、CH(CH3)COOCH3Or CH (CH3)COOC2H5；
The dyestuff B is compound shown in following formula (II):
Preferably, it is made of following components by weight percent:
Dyestuff A:5-30%, dyestuff B:10-30%, remaining is auxiliary agent.
Preferably, in formula (I), R1For CH2COOC2H5。
Preferably, in formula (I), R1For CH2COOCH2COCH3。
Preferably, in formula (I), R1For CH (CH3)COOCH3。
Preferably, the auxiliary agent is one or both of MF or sodium lignin sulfonate.
A kind of preparation method of the orange disperse dye mixture of high washing fastness be by formula (I), (II) and auxiliary agent press than
Example mixing, adds water sand to grind, and is spray-dried, to obtain orange disperse dye mixture.
Orange disperse dye mixture produced by the present invention is applied to dyeing and the stamp of terylene or blend.
The beneficial effects of the present invention are: orange disperse dye mixture of the invention has high washing fastness, because of this hair
The solubility parameter ratio Br-19 and Y-246 of dyestuff A and dyestuff B in bright closer to terylene solubility parameter, thus with fabric
Binding force is bigger greatly, and washed agent is not easy in washing and is extracted from fabric, in addition, containing in the structure of dyestuff A and dyestuff B
Have on ester group and phenyl ring containing-Cl, after dyeing when loose colour alkali process ,-CH easy to form2CH2COONa and phenol sodium and lead to fabric
On loose colour easily wash away, thus each contribute to improve dyestuff washing fastness.
Specific embodiment
Embodiment 1
Dyestuff A 10g, dyestuff B 20g and auxiliary agent 70g (MF 30g, sodium lignin sulfonate 40g) is weighed according to weight ratio,
And be sanded together with 100g water, orange disperse dye mixture is made in spray drying.
It wherein, is R in formula (I)1For CH2COOC2H5, solubility parameter σ=10.57 of the compound.
Embodiment 2-5
Embodiment 2-5 is made respectively, and production method is same as Example 1, is only R in proportion and formula (I)1Group occurs
Variation, specific as shown in table 1:
The structure of 1 embodiment 2-5 of table and specific proportion
Comparative example
Production method is same as Example 1, and wherein Y-246 is 20g, Br-19 10g, auxiliary agent be 70g (MF 30g, it is wooden
Plain sodium sulfonate 40g), water 100g.
Experimental result
Orange disperse dye mixture obtained by embodiment 1-5 and comparative example is respectively taken into 1g, is scattered in 500mL water,
20mL dispersion liquid and 80mL water are respectively taken after mixing, with acetic acid tune PH to 4-5,2g dacron ultrafine fiber are then added, by national standard GB/
T2394-2006 method carries out dyeing processing, and washing fastness is tested by GB/T3921-2008, and concrete outcome is as shown in table 2.
