Description
Technical field
The invention belongs to technical field of disperse dyes, and in particular to a kind of preparation method of strong basicity resisting dispersion dye.
Background technology
The dyeing process of polyester fiber mainly uses solutions of weak acidity (pH value 4.5-5.5) to dye, because existing
Most of disperse dyes not alkali resistance, i.e. disperse dyes are unstable under the conditions of alkaline (such as pH value be 9-11), easily generation
Metachromatism.But disperse dyes dye under mildly acidic conditions, following weak point is primarily present：
(1) work flow is grown, and processing water consumption is high, and discharge amount of pollution is big；
(2) oligomer inside polyester fiber can not be removed, had both had influence on the feel of product, and is easily formed in fabric face
" tar stain ".
With the appearance of dacron ultrafine fiber or superfine composite fiber, in order to make superfine fibre or superfine composite fiber thorough
Separate (i.e. fibrillation), need to process in the basic conditions.If the fibrillation of dacron ultrafine fiber or superfine composite fiber is not
Completely, the feel of fabric and the uniformity of dyeing are influenced whether, then when carrying out secondary fibrillation, because disperse dyes alkali resistance compared with
Difference, the color and luster of dyed fabric can be caused to change.The key for solving problems is to prepare the disperse dyes of alkali resistance, disperse dyes
Alkali resistance it is higher, use range is wider.Therefore, the disperse dyes that research prepares alkali resistance have good market prospects.
The content of the invention
It is an object of the invention to provide a kind of preparation method of strong basicity resisting dispersion dye, the present invention be resistant to sodium hydroxide or
The strong alkali solution of sodium hydroxide and borax composition, the application of disperse dyes is expanded significantly, shorten dacron print
The technological process of processing is contaminated, serves the effect of energy-saving and emission-reduction.
A kind of preparation method of strong basicity resisting dispersion dye, its step are as follows：
Step 1, dyestuff is subjected to ethanol water immersion, obtains dyestuff alcohol solution；
Step 2, emulsifying agent, bleeding agent and initiator are added in dyestuff, obtain dyestuff mixed liquor；
Step 3, dyestuff mixed liquor is added into reactor, adds alkaline-resisting resin and carry out sealing ammonia compressive reaction；
Step 4, dispersant is added after question response terminates and carries out vacuum distillation reaction, obtains alkali-resistant dispersed dye.
Dyestuff in the step 1 uses azo dyes.
Concentration of alcohol is 50-70% in ethanol water in the step 1.
Emulsifying agent in the step 2 uses liquid crystal emulsion or gel emulsion.
Bleeding agent in the step 2 uses AEO.
Initiator in the step 2 is using benzoyl peroxide, lauroyl peroxide, benzoyl peroxide, peroxidating
One kind in lauroyl.
Basic resin in the step 3 uses alkalescent phenol resin or macropore styrene strong alkali resin.
Pressure is 1.5-3.3MPa in closed ammonia compressive reaction in the step 3.
Dispersant in the step 4 uses sodium polyphosphate.
A point vacuum distillation reaction temperature in the step 4 is 70-100 DEG C, reaction time 80-150min.
Compared with prior art, the invention has the advantages that：
1st, the present invention is resistant to the strong alkali solution of sodium hydroxide or sodium hydroxide and borax composition, expands disperse dyes significantly
Application, the technological process of dacron dyeing and printing process is shortened, serve the effect of energy-saving and emission-reduction.
2nd, the present invention can not only use the weak base such as sodium carbonate, sodium carbonate hydrogen sodium to adjust, and can be adjusted with highly basic such as sodium hydroxides
Section, expand the application of basic dyeing.
3rd, the present invention be in the basic conditions in use, other alkali resistance disperse dye levelling agents need not it is possible to additionally incorporate,
Just there is good even dyeing effect.
