Description

A kind of high washing fastness dispersed black dye mixture
Technical field
The invention belongs to dye mixture technical fields, and in particular to a kind of high washing fastness dispersed black dye mixture.
Background technique
1. there is superfine fibre with the development of polyester fiber, since it is with superfine diameter, biggish surface The features such as product makes its fabric have high spreadability, soft, comfortable and easy to wear, it has also become domestic and international textile enterprise fall over each other using Textile raw material, in dyestuff used at present, most dyefastness is poor, and especially washing fastness is not achieved 4 grades.
2. influence disperse dyes washing fastness there are two aspect, first is that the cleaning of dyeing loose colour, second is that dye migration is to table Face.In the dyeing course of dyestuff, always there is a small amount of dyestuff and not can enter the inside of fabric, surface, the dye on surface can only be adsorbed on Material is known as loose colour, these dyestuffs seriously affect the washing fastness of fabric, the loose colour of fabric handle after dyeing in handle not completely, Cause other fabric staining in subsequent laundering process, i.e. washing fastness is poor, on the other hand, even if dyestuff enters in dyestuff Portion, under detergent and temperature action, a small amount of dyestuff is drawn out, and is adsorbed on fabric surface, to influence fastness.
3. dispersing the high good colourant of black washing in the market by palm fibre 19, red 311, blue 284 blendings are formed, and trade name dispersion is black XF, dosage is larger, and palm fibre 19, red 311 has propionic acid ester group, handles in alkaline cleaning procedure after dyeing, and-CH2CH2COO easy to form is negative Ion and wash away, exist after blue 284 alkali cleanings without soluble groups, thus disperse black XF washing fastness less than 4 grades, can not meet print Contaminate requirement of the industry to fastness.
Therefore it is badly in need of a kind of high washing fastness dispersed black dye mixture for being able to solve existing issue.
Summary of the invention
Present invention aim to address the dye mixture washing fastness of the prior art is poor, a kind of high washing fastness is provided Disperse black mixture, dyeing and stamp for terylene or blend.

A kind of high washing fastness dispersed black dye preparation method of mixture be by formula (I), (II), (III) and auxiliary agent press than Example mixing, is sanded, and obtains dispersed black dye mixture by spraying.
The present invention is applied to dyeing and the stamp of terylene or blend.
The beneficial effects of the present invention are: the dyestuff of this patent formula (I), formula (II), is handled in alkaline cleaning procedure after dyeing, it is even The chlorine of the meta position of nitrogen base is easy to form phenol sodium under alkalinity, so that fabric surface loose colour is formed with the presence of electrophilic nitro Water-soluble dye, formula (III) can not only form phenol sodium, and the acetate groups being coupled on component, alkali process can form-CH2COO Anion can obtain preferable washing fastness.
Specific embodiment
Below by specific example, the present invention is explained:
Wherein formula (I) refers to that disperse blue, formula (II) refer to that disperse violet, formula (III) refer to disperse orange, wherein makes in embodiment 1-18 Use, I-1 to I-5, II-1 to 5 and III-1 and III-2 are recorded in summary of the invention, herein with it is upper identical, therefore no longer Repetition is write out.
Embodiment 1
By disperse blue (I -1) 17g, disperse violet (II -1) 15g, disperse orange (III -1) 25g, auxiliary agent MF20g, lignin sulfonic acid Then sodium 85A23g, water 200g, sand milling of putting together are spray-dried to get dispersed black dye mixture of the invention.
Embodiment 2-18
Embodiment 2-18 is made respectively, and production method is same as Example 1, specific proportion such as the following table 1:
The specific proportion of 1 embodiment 2-18 of table
Embodiment 19
1g is respectively taken using embodiment 1-18 and the commercially available black XF of dispersion as reference examples, is scattered in 500ml water, mixes 20ml dispersion liquid and 80ml water are respectively taken afterwards, with acetic acid tune PH=4-5, the dyeing of 2g terylene woven fabric fabric are added, by national standard GB/ T2394-2006 method carries out dyeing processing, and washing fastness is tested by GB/T3921-2008, dye uptake by GB/T9337-2001 into Row.
Table 2 is the test result (unit: grade) of the washing fastness dye-uptake of embodiment 1-18
The black dyeing washing fastness for terylene or its blended fabric of dispersion of the invention is excellent as can be known from the above table, dye uptake Also it is greatly improved, is higher than comparative example.
Principle
The dyeing course of dyestuff can regard dyestuff course of dissolution on chemical fibre as, and fastness quality and migration difficulty or ease can use dissolution Degree parameter judges, in general, the solubility parameter of dyestuff closer to terylene solubility parameter (σ=10.8, research shows that It is good that difficult and fastness is migrated within σ=10.8 ± 0.5) fastness is better, and dyestuff is fixed also better on the fabric, and dyestuff is less susceptible to move Move on to fabric surface.In disperse blue (I), disperse violet (II) and disperse orange (III) structure, the solubility parameter of dyestuff is 10.3 Between~11.2, (palm fibre 19, red 311, blue 284 solubility parameters are respectively the solubility parameter closer to terylene XF more black than dispersion 10.09/10.42/10.4), especially selected dyestuff, the solubility parameter of the fairly close terylene of solubility parameter, thus this The more difficult migration of the compound of patent, meanwhile, the dyestuff of this patent formula (I), formula (II) is handled in alkaline cleaning procedure after dyeing, even The chlorine of the meta position of nitrogen base is easy to form phenol sodium under alkalinity, so that fabric surface loose colour is formed with the presence of electrophilic nitro Water-soluble dye, formula (III) can not only form phenol sodium, and the acetate groups being coupled on component, alkali process can form-CH2COO Anion can obtain preferable washing fastness, and therefore, dispersed black dye mixture of the invention has high washing fastness.
These are only the preferred embodiment of the present invention, is 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 in spirit of the invention and Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
