Description
Technical field
The present invention relates to the technology of preparing of ink for digit printing silk broadcloth textile, be specifically related to a kind of based on fibre
Dimension element nanosphere is the preparation method of the silk broadcloth stamp nanometer ink of dispersant.
Background technology
Digital ink-jet printed is required pattern input meter by various input mediums (scanner, digital camera etc.)
Calculation machine, after computer color separation in printing retouches original text system (CAD) editing and processing, is controlled minute-pressure electric-type ink nozzle by computer, uses
Ink (activity, reduce, disperse, the special dye liquor such as acid) is directly ejected into various by jet printing system by RIP software
Stamp is carried out, after treatment, it is thus achieved that be printed on the textile of patterns of high precision on fabric.Additionally use C, M, Y, K (blue or green, pinkish red,
Yellow, black) four color ten spot color stamp shower nozzles, so that it may print off 1670 million colors, i.e. can reach various decalcomania requirement.
Compared with Conventional decal, this technology has abandoned operations such as retouching original text, film-making, net processed and engraving in Conventional decal, has
Energy-conservation, reduce discharging and the advantage such as environmental protection, be the stamp new technique the most generally having an optimistic view of.In recent years, along with people are to " personalized clothes
Decorations " demand increasing, fast pace, the stamp order of small lot the most progressively become the main flow in stamp market.Traditional round wire mark
Flower is complicated due to the course of processing with PLATE SCREAM PRINTING, troublesome poeration, small lot batch manufacture cost high with delivery cycle length etc. defect, own warp
Can not meet the paces of " small lot, multi items, fast pace produce ".Ink-jet printed cater to people's required design manufacture
(DAMA) and the life style of prompt delivery (JIT), there is development prospect well.But, at digital inking printing product
While having obtained favorable comment and the accreditation of more and more consumer, high stamp cost is still.
Ink is as the important consumptive material in digit printing production, and its research and development are to promote that digital ink-jet printed technology is sent out
The committed step of exhibition.In the market, for the digit printing ink of silk broadcloth textile, mainly with water-soluble reactive colour or
Acid stain is main, containing a large amount of strong water-soluble groups in these molecular structure of dye, and the color representability of dye ink
Abundant, its colour gamut can compare favourably with Conventional decal.The ink-jet printed ink set of reactive dye generally comprises colorant, water or has
The additive compositions such as machine solvent, viscosity modifier, surfactant, wetting agent, anti-microbial inoculum, plugging inhibitor, pH adjusting agent.Fabric
With ink-jet printing ink except to pigment purity, insoluble solid grain diameter and the viscosity of ink, surface tension, conductance
Rate, stability, pH value and foaming characteristic etc. have outside specific requirement, after also requiring that ink is ejected on fabric formation pattern, and must
Must have good water-fastness color fastness, and fabric feeling can not be affected.But these small molecule dyes inks are not only deposited at spray printing
At the best (CN103526570A of stability and mobility；And on printing fastness, there is also the biggest asking CN102936434A),
Topic so that fabric color is the most bright-coloured, and generally require repeatedly washing in the fabric post-treatment stage and could remove and do not consolidate
The dyestuff of color, does not meets the requirement economized on resources.
Studies in China person has used monomer or oligomer to instead of macromole binding agent so that ink is in jet printing process
Good stability be guaranteed.Additionally, they also introduce the polystyrene microsphere of ordered structure, polystyrene-methyl-prop
Olefin(e) acid microsphere and silicon dioxide microsphere are as the stabilizer (CN102719145B of dye molecule；CN103788770A；
CN102926224A), in conjunction with " structure add lustre to bionical dye technology " and digital ink-jet printed technology, it is digital that textile is prepared in trial
The colloid micro ball ink that printing structure adds lustre to.Employed in it, bionical dye technology is not only difficult to large-scale production, and should
Technical pattern regulation and control are the most complex；Additionally, masterplate microsphere is all uncharged microsphere, the strongest with dyestuff adhesion.Also grind
The person of studying carefully utilizes the reaction of water-soluble dye and high polymer to prepare water soluble polymer dyestuff (CN103319953), and the method is logical
Cross various reaction path hung on by water-soluble dye on the side chain of high polymer or be combined with high-polymer molecular and obtain aqueous height
Molecular dye.Such as N, O-CMC is as the skeleton of high molecular dye, and it is soluble in water, can by with activity
Dyestuff occurs homogeneous graft reaction to prepare water soluble polymer dyestuff in aqueous.But, the dyestuff kind that this method is suitable for
Class is less.
And the present invention is with electronegative cellulose nanospheres as dispersant, utilize its electronegative surface group and dyestuff
There is electrostatic interaction, and then preferably dye molecule is combined on nanosphere, it is achieved its fine dispersion, and pass through simple process
Compounding, prepare the high-stability nano ink that can be applicable to digit printing silk broadcloth textile.This preparation technology not only cost
Relatively low, can industrial-scale production, and whole process environmentally safe.Gained ink not only has conventional inks anticorrosion, color
The advantage such as color distinct, is provided simultaneously with that high Zeta potential, ink grain size be little and equal first-class feature, solves ink-jet printing ink
Easily block shower nozzle during injection and cause the slack problem of printing, also improve the problem that ink long-time storage is unstable simultaneously,
Widen the digital ink-jet printed technology prospect of the application in silk broadcloth market.
Summary of the invention
The technical problem to be solved is to provide a kind of based on the silk broadcloth print that cellulose nanospheres is dispersant
The flower preparation method of nanometer ink, the method preparation technology is simple and easy to operate, with low cost；Whole preparation process to environment without
Pollute, be suitable for industrial-scale production；Obtained digital ink-jet printed ink has that grain size is little and narrowly distributing, size
