Description

Aqueous pigment digital ink-jet printing in textiles ink and its preparation and application
Technical field
The present invention relates to a kind of aqueous pigment digital ink-jet printing in textiles inks and preparation method thereof, while being related to the ink Water ink-jet printed method on the fabric.
Background technique
Traditional silk screen, rotary scream printing operating procedure complexity are tediously long, and are not able to satisfy high-quality, small lot, style multiplicity Change, personalized requirement, and digital ink-jet printed technology gets rid of Conventional decal color separation, plate-making, the analog form for making net, has The clear superiority of easy to operate, pollution-free, low energy consumption, high repayment brings unprecedented opportunity to develop to textile printing and dyeing industry. Digital ink-jet printed is that required decalcomania is inputted in computer in digital form, scans and edits by computer color separation in printing After processing, in the digital inkjet printing machine by computer control, directly printing ink is accurately ejected on fabric, is printed Various required color patterns out.Digital ink-jet printed ink is the important consumptive material of digit printing, and the property of digit printing ink Printing quality can be directly influenced, the digital ink-jet printed ink of presently used fabric contaminates mainly based on dye ink Expect that there are shortcomings for ink: (1) dye ink does not have versatility.Different fabrics needs different types of dye ink It is able to satisfy stamp requirement, since replacement ink needs cleaning sprayer and pipeline, causes to operate more troublesome；(2) production technology is complicated, There are certain environmental pollutions.It needs to pre-process fabric before ink-jet printed, needs to carry out gas steaming to fabric after ink-jet printed The post-processings such as fixation, washing removal loose colour, the process is more complicated, and energy consumption is higher.Fabric post-processing stages generally require more Secondary washing could remove the dyestuff not being securely held, because will cause certain environmental pollution；(3) light fastness is poor.One As dyestuff be all low molecular weight water-soluble dye, easily decompose under illumination condition, causing to fade changes colour, and influences the product of PRINTED FABRIC Matter.
The disadvantages mentioned above of dye ink hinders the popularization of digital ink-jet printed technology, therefore exploitation is avoided that dye ink The task of the novel ink-jet printing ink of disadvantage is extremely urgent, and pigment ink-jetting printing ink comes into existence as the situation requires.Pigment jetting print Flower ink, in the film forming mechanism of fabric surface, will be adhered on the fabric based on adhesive without compatibility and reactive pigment, Using the surface for making pigmentation and being firmly secured to fabric is baked, to assign the gorgeous color of fabric and figure abundant Case.Pigment ink-jetting printing ink can be common to various fabrics, such as cotton, hair, silk, cotton synthetic fibre, dacron and blended fabric, spray Transformation fabric variety does not need replacement ink and cleaning sprayer and pipeline during ink-printed, and ink waste is less, hardly dirty Contaminate environment.In addition, the simple process of pigment ink-jetting printing ink, no post-processing and washing process, water-saving, power saving, low energy consumption. Therefore pigment ink-jetting printing ink is it will be apparent that still the technology exists still at present for the advantages of textile ink-jet stamp An open question: failing to find suitable textile binding agent, low so as to cause ink-jet printed product washing fastness.
Currently, be applied to textile coating stamp adhesive be usually polyacrylate or polyaminoester emulsion and they Modified resin, wherein polyacrylate adhesive with it is relatively broad.Polyacrylate dispersion fabric surface at The film transparency is good, stronger to the adhesive capacity of fiber, and has preferable water resistance, weatherability and mechanical property, but there are hands Sense is easier to the disadvantages of hard, hot sticky cold crisp.Aqueous polyurethane emulsion it is good at film dynamic performance, it is with higher elasticity and it is good Permeability, and heat-resisting, cold-resistant, resistance to bent mill, feel particularly soft, fastness to wet rubbing and smoothness are good, and epithelium is not tacky, does not adsorb Dust.As long as traditional coating printing adhesive size not network blocking, and if carrying out use as ink-jet printed adhesive, tradition Coating printing adhesive emulsion stability is inadequate, and partial size is too big, is easy the expensive piezo jets of blocking, thus cannot be used for ink-jet Stamp.The ink-jet printed requirement to adhesive is: (1) emulsion particle diameter can be stablized and not be demulsified under nanoscale, high and low temperature； (2) emulsion film forming is firm and elasticity is good, and cementitiousness is strong, and washing fastness is high；(3) it forms a film soft, not tacky.
Have about the most representative patent of aqueous pigment type ink-jet ink containing polyacrylate dispersion US7338988, US70301175, but the ink-jet ink in these patents is mainly for the plastic films material such as PP, PVC, PU Coloring, the glass transition temperature of polyacrylate dispersion used is above room temperature, forms hard film on ground, it is clear that It may not apply to soft fabric.Domestic room width is completed et al. to carboxylic acid-based copolymer in aqueous pigment ink-jet printing ink The dual function of pigment hyper-dispersant and textile binding agent is played simultaneously, but carboxylic acid-based copolymer comes from hyper-dispersant angle It sees, due to lacking single-point or multiple spot pigment anchoring group, and solvent free chain in macromolecular chain, therefore is copolymerized through polyocarboxy acid type The pigment stability of object hyper-dispersant will not be satisfactory；From the perspective of textile binding agent, carboxylic acid-based copolymer oversubscription Powder content is less, although esterification occurs with cellulosic fabric, hardly reacts with chemical & blended fabrics such as terylene, nylon, Therefore bonding effect is not ideal enough.Crosslinking agent is added in pigment ink-jetting printing ink by patent CN101100815, to improve Dry, fastness to wet rubbing, but effect is still not ideal enough, fastness to wet rubbing only have 2-3 grades, and 3-4 grades of dry fastness, and actually face If existing in material type ink-jet printing ink if there is crosslinking agent, then all may at any time in the transport of ink or storing process Reaction is crosslinked, causes the storage stability of ink bad, and prints fluency and also will appear serious problems.Patent CN1583898 uses self-crosslinking acrylic ester resin as plant adhesive, the results show: fabric surface after stamp Crosslinked polyacrylate film is relatively hard and crisp, easily falls off from fabric after dry state or hygrometric state friction, washing fastness is reduced to 2 Grade.E.I.Du Pont Company in recent years disclosed patent WO2005/071026, WO2009/076386, WO2009/137747 to have Adhesive of the polyaminoester emulsion of cross-linked structure as ink-jet printing ink, but the washing fastness of fabric still will not be high, The polyaminoester emulsion adhesive and crosslinking agent with cross-linked structure is added in WO2009/137753 simultaneously in the ink, and in ink Existing crosslinking agent easily causes the crosslinking of ink polyurethane in transport or storing process, cause ink storage stability, It is bad to print fluency.
