Description
Technical field
The invention belongs to digital ink-jet printed fields, and in particular to a kind of digit printing disperse dye ink and its preparation
Method.
Background technique
Disperse dyes are various in style, chromatography is complete, function admirable, are widely used, it has also become with fastest developing speed in all kinds of dyestuffs
One of dyestuff.Disperse dyes are mainly used for dyeing and the stamp of terylene and its textile, it can also be used to acetate fiber and polyamide fibre
The dyeing of fiber textile and stamp；Direct printing both can be used in dyeing and printing process, and transfer printing can also be used.
In recent years, with the rapid development of electronic computer technology.Paper inkjet printing technology is applied to weaving by people
The industries such as product stamp, advertising painting.Especially in textile printing and dyeing industry, digital ink-jet printed technique is short with process with it, delivers goods
Fastly, the extensive concern of dealer can be caused outstanding advantages of small lot production.With continuously improving for ink-jet printing equipment, especially
The continuous improvement of ink-jet decorating machine performance (breadth, resolution, print speed etc.) and the gradually decline of ink-jet ink price, this
Future of the technology for industrialization production is more and more brighter.
Colorant used in ink-jet printing ink mainly has dyestuff and two kinds of coating.It is related living in dye class ink
Property dyestuff, acid dyes, direct dyes are used to prepare the research of textile inkjet printing ink, there is lot of documents report both at home and abroad
Road, and research report of the disperse dyes for ink-jet printing ink is then relatively fewer.Disperse dyes are in textile inkjet printing side
Face, which is applied, is no more than water-soluble dye, mainly since there are processing difficulties, at high cost, easily blocking spray head, storage stability is poor
The problems such as.
Herein on the basis of disperse dyes, dispersing agent and cosolvent through screening are refined, purified, dyestuff is carried out
The composition research of ink analyzes dispersing agent performance, processing and storage temperature, pH value, grain fineness, inorganic salt content to dispersion
The influence of dye ink performance, acquired results have excellent storage stability to preparation, the ink-jet printed of blocking sprayer does not use disperse dyes
Ink reference value with higher.
In ink-jet printed, dye ink be influence Printing quality one of key factor, generally by pigment, water or
Organic solvent, additive composition.Dye ink is in addition to pigment purity, insoluble solid grain diameter, the viscosity of ink, surface
Tension, stability, pH and foaming characteristic etc. have except specific requirement, also require after forming pattern in ink injection to fabric, have
Good water-fastness, rub resistance etc..It is mostly reactive dye, acid dyes or dispersion dye that ink is used in existing industrial textile
Expect ink, wherein disperse dye ink use scope is maximum, using also the most mature.
Disperse dyes are with a wide range of applications for ink-jet ink research.Especially there is nothing in advertising and printing outdoors
It is good with the advantage of rival, such as light fastness, the secondary air brushing on cloth can be washed off with water, against weather is good, it can also be used to stamp
Deng other aspects.
The performance of storage stability and not blocking sprayer is the key index of Disperse dye ink-jet ink performance, influence factor
The predominantly pH value of dispersible ink, grain diameter and inorganic salt content etc.；In the processing of ink etc., storage and print procedure,
It is all influenced by pH, dyestuff pH value control in mashing grinding is preferable in 7-8 or so, and dyestuff is preferable 8 or so in storage, is beating
Also it is preferable that 7-8 is controlled at when print.
Particle diameter has a significant impact to the stability of ink-jet ink.According to Stokes' law, the particle in gravitational field
Sinking speed and particle diameter it is square directly proportional.So particle is bigger, sinking speed is faster, it is easier to make system by
It destroys.According to multiple performance measurement and the actual result of inkjet printing, it is believed that particle diameter main body, which should control, to be carried out: 0.2 is micro-
Meter or less.
Most of inorganic salts are electrolyte, in water easily ionizable, when inorganic method carries out；When salinity increases, will have
The more charge electrically opposite with adsorption layer enters adsorption layer.Zeta when absorption layer charge is fully neutralized, in micelle
Current potential is down to zero, and the electrostatic repulsion for asking micelle becomes smaller, and even disappears completely, and greatly reduces the anti-coagulation ability of dispersion,
And make storage 6 months, observe its precipitating degree and printing effect；The stability of entire dispersion is destroyed.
Existing disperse dye ink is mainly as with disperse dyes, water existing for molecule, surfactant and polyalcohol
Etc. material compositions, but disperse dye ink stably dispersing performance is poor at present, is difficult to take into account the upper of disperse dyes during the preparation process
All indexs for influencing stability are stated, cause the particle granules of disperse dye ink big, pH value does not reach requirement, inorganic content mistake
It is high, when use easily blocking spray head the defects of, and the storage stability of disperse dye ink is bad, constrains it and prints in weaving
The extensive use in dye field.
Therefore, it is urgent to provide the disperse dye inks for being not easy to plug spray head when a kind of dispersion high stability, use to have weight
Want meaning.
Summary of the invention
In order to solve shortcomings and deficiencies of the prior art, the present invention provides a kind of digit printing disperse dye ink,
With the better effects such as degree of fixation is high, dye content high-performance temperature can store for a long time.

It is poly-, cause the particle granules of disperse dye ink larger, particle diameter distribution is wide, and stably dispersing performance is poor, exists so as to cause ink
Spray head is easily blocked in use process, and adhesive force is low between disperse dye ink and fabric, it is necessary to by the effect of adhesive
It can just anchor on fiber, the defect restricted its application provides a kind of preparation method of disperse dye ink.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that:
A kind of digit printing disperse dye ink, which is characterized in that the dispersible ink includes following mass fractions
Component:
30-80 parts of disperse dyes, 10-30 parts of organic solvent, 0.5-10 parts of composite dispersing agent, 5-15 parts of surfactant,
0.1-0.5 parts of fungicide, 0.02-0.5 parts of pH adjusting agent, 30-70 parts of deionized water；The composite dispersing agent is dispersed by macromolecule
Agent and dispersion aids composition, the mass ratio of the two are 1:0.1-10, and the macromolecule dispersing agent is poly- for polyurethane anion
Close object；The dispersion aids is at least one of peregal or lignin.
Dispersing agent for water-based system can be divided into 3 classes: inorganic dispersant, small organic molecule dispersing agent and molecule dispersion
Agent.Inorganic dispersant is readily incorporated new foreign ion, and small organic molecule dispersing agent dispersion stabilization is weak, and dispersion effect is poor, because
