Description
Technical field
The present invention relates to a kind of ink-jet printing method and employed ink-jet printed equipment and ink-jet printing ink, particularly a kind of textile or contain at least on the cotton fabric more than 50% and directly carry out ink-jet printed method, ink-jet printed equipment and ink-jet printing ink.
Background technology
Digital ink-jet printed a kind of advanced technology as textile industry by the computer control sprayed printed system, is directly injected to ink fabric faces such as cotton, fiber crops, silk, chemical fibre, thereby prints off various patterns and decorative pattern.Compare with traditional printing technology, the digital ink-jet printed plate-making process of saving, production efficiency height and production process are pollution-free.
The digital ink-jet printed ink of using mainly contains two classes at present: dye-type and color type.Type of dye ink is divided into DISPERSE DYES, ACID DYES and three kinds of inks of REACTIVE DYES according to the difference of use dyestuff, because type of dye ink is to react with fiber by dyestuff to combine, so at different fibers, need to select different dye inks, wherein pure cotton fabric is subjected to the restriction of its fabric self character, adopts reactive dye ink more.The ink-jet printed complex process of type of dye ink, fabric need starching to handle, and also need operations such as decatize, washing, oven dry behind the spray printing, can produce the contaminated wastewater environment in process of production, and the fabric light resistance of producing is poor.And the pigment in the pigment ink does not react with fiber, is to combine with fiber by media, and printing technology is simple, can carry out direct spray printing, adds the fast light and water-tolerant of pigment ink, therefore earns widespread respect in recent years.
Pigment does not all have affinity to any fiber, that is to say pigment itself can not on dye, anchor on any general fibre.Therefore in the ink-jet printed process, mainly be by in the pigment jetting printing ink, using adhesive, utilize the gluing filming performance increase ink of adhesive and the caking property between the fabric, thereby in curing the fixation process, form printed film continuous densification, that have anti-dried wet friction performance at fabric face.But because adhesive mostly is macromolecule bulky grain resin, not only cause the printing fluency of ink poor easily, in ink-jet printed process, stop up shower nozzle easily, also can cause storage stability bad, be easy to deposition.
Summary of the invention
One of the technical problem to be solved in the present invention provides a kind of new inking printing pigment ink that is applicable to pure cotton fabric or contains the fabric of at least 50% cotton, has the excellent storage good stability, and is difficult for stopping up shower nozzle.
For solving the problems of the technologies described above, technical scheme provided by the invention is: inking printing pigment ink, it is characterized in that, and by weight percentage, comprising: 10%-30% organic pigment dispersion liquid; The 0.1%-25% adhesive; First kind of material of 0.1%-10%; Second kind of material of 0.1%-10%; The 1%-30% wetting agent; The 1%-20% bleeding agent; The 30%-60% deionized water; Wherein, first kind of material is for having general formula R-O-Q
nA
-M
+Compound, wherein R is alkyl, aryl, alkaryl or alkylene; Q is the ethyoxyl or the propoxyl group of repetition, and 4＜n≤10; A
-Be sulfate radical, sulfonate radical or phosphate radical; M
+Be potassium ion, sodium ion, lithium ion or ammonium ion; Second kind of material is for having general formula X Q
nThe compound of R '-Y-R, wherein X is hydroxyl or amino; Q is the ethyoxyl or the propoxyl group of repetition, and 4＜n≤10, and R ' is the alkyl of C1 to C6; Y is oxygen, nitrogen or sulphur; R is alkyl, aryl, alkaryl or alkylene.
When first kind of material among the present invention and second kind of material are dispersed in pigment and surface of pressure-sensitive adhesive, form film or electric double layer, can make decentralized photo have electric charge, condense mutually with the droplet that stops decentralized photo, thereby form stable emulsion, the deposit of ink of having avoided granules of pigments and adhesive particle aggregation to cause has not only improved the storage stability of ink, has also improved the utilization rate of pigment and the resistance to water of ink.In addition, first kind of material and second kind of material are used, and can play good synergy.In addition, the present invention has improved the printing fluency of color type textile ink effectively by the consumption of choose reasonable each component, prevents to stop up shower nozzle.In addition, can also promote the affinity between pigment and the fabric, improve the wash durability of fabric.
Another technical problem that the present invention will solve provides a kind of textile or contain at least on cotton 50% the fabric and use above-mentioned inking printing pigment ink to form method for printing.
For solving the problems of the technologies described above, technical scheme provided by the invention is: ink-jet printing method may further comprise the steps: with any inking printing pigment ink in the claim 1 to 5 with ink-jet printed device spray printing to textile or contain at least on cotton 50% the fabric; Fabric is heated 30 seconds to 3 minutes fixation of fixation in temperature under 150 ℃ of-180 ℃ of temperature.
