Referring to fig. 1 and fig. 2, fig. 1 and fig. 2 are schematic flow charts of an inkjet printing method according to an embodiment of the present invention. As shown in fig. 1 and 2, the inkjet printing method includes the steps of:

s11, spraying wetting liquid on the surface of the fabric by a spraying device to form a wetting liquid layer;

in the embodiment, a layer of wetting liquid is sprayed on the surface of the fabric by adopting spraying equipment, the interior of the spraying equipment is in a dust-free environment, and the temperature inside the spraying equipment is 20-30 ℃. The spray apparatus may include a fountain solution spray head and a first platen disposed below the fountain solution spray head. The fabric is flatly laid on a first platen of the spraying device, and the spraying device sprays the wetting liquid on the surface of the fabric through the wetting liquid spray head. Optionally, the spraying equipment in the embodiment of the invention may be a spraying box; the wetting fluid in embodiments of the present invention comprises water and at least one organic solvent. Optionally, the wetting fluid may further comprise one or more of a self-adhesion promoter, a viscosity modifier, a thickener and a surface tension modifier. Also, the surface tension of the wetting fluid is lower than the surface tension of the ink. To improve the printing of the target pattern, the surface tension of the wetting fluid is at least 1 dyne/cm less than the surface tension of the ink.

Referring to fig. 3, in some embodiments, before the spraying device sprays the wetting fluid, the spraying parameters of the spraying device may also be adjusted, wherein the spraying parameters include at least one of a spraying range of the wetting fluid, a type of the wetting fluid, and a spraying amount of the wetting fluid. Before step S11, the inkjet printing method further includes the steps of:

s101, determining the spraying range of spraying equipment according to the size of the picture of the target pattern to be printed;

in some embodiments, in order to reduce the waste of the wetting liquid, before spraying the wetting liquid, the spraying range of the spraying device needs to be adjusted according to the size of the picture of the pattern to be printed, so that the shape and size of the area on the fabric sprayed with the wetting liquid are matched with the shape and size of the pattern to be printed. Therefore, spraying can be realized as required, the effective utilization rate is high, and waste can not be caused.

S102, determining the type of the wetting liquid according to the color system of the fabric;

when the color of the fabric is dark, the fabric belongs to a dark color system, and in order to avoid the influence of the color of the fabric on the color finally presented by the target pattern, white ink needs to be sprayed on the wetting liquid after the wetting liquid is sprayed, and then color ink needs to be sprayed on the white ink to form the pattern. At this time, in order to improve the color fastness of the target pattern and make the printed target pattern more vivid in color, the wetting liquid should react with both the white ink and the color ink. When the color of the fabric is light, the fabric belongs to a light color system, the color of the fabric hardly influences the presentation effect of the target pattern, and the wetting liquid is directly sprayed with the color ink instead of being sprayed with the white ink, so that the wetting liquid only needs to react with the color ink. Therefore, in this embodiment, the type of wetting fluid needs to be determined according to the color system of the fabric before spraying the wetting fluid. Alternatively, the type of wetting solution may be classified into a dark-color-system wetting solution and a light-color-system wetting solution, and the dark-color-system wetting solution is sprayed when the fabric is a dark color system, and the light-color-system wetting solution is sprayed when the fabric is a light color system.

S103, determining the spraying amount of the wetting liquid according to the color system of the fabric;

since for dark fabrics, the fountain solution sprayed therefrom needs to react with both white and color inks; for light-colored fabrics, the sprayed wetting liquid only needs to react with the color ink; thus, to ensure that the ink reacts well with the fountain solution, the amount of fountain solution applied to the dark colored web is generally higher than the amount of fountain solution applied to the light colored web. Typically, the amount of dark fabric fountain solution sprayed is from 0.01 to 0.04g/cm²The spraying amount of the wetting liquid of the light-color fabric is 0.005-0.03g/cm². Optionally, in order to obtain better printing effect, the spraying amount of the wetting liquid on the surface of the fabric is 0.020g/cm²。

Optionally, in some embodiments, the step S11 includes:

s104, spraying wetting liquid on the surface of the fabric according to the determined spraying range of the spraying equipment, the type of the wetting liquid and/or the spraying amount of the wetting liquid;

in some embodiments, after step S11, the inkjet printing method further comprises the following steps:

step S105, uniformly scraping and coating the wetting liquid on the surface of the fabric;

since the wetting fluid is sprayed onto the fabric in the form of droplets, the wetting fluid on the fabric consists of countless drops of the wetting fluid, which are thick in the middle and thin on the periphery, and there may be regions between the drops that do not cover the wetting fluid, resulting in an uneven distribution of the wetting fluid over the surface of the fabric. In order to enable the surface of the fabric to form a wetting liquid film with uniform distribution and moderate thickness, and facilitate the printing of a subsequent target pattern, after the wetting liquid is sprayed by the spraying equipment, the wetting liquid on the surface of the fabric can be uniformly coated by a scraper. For example, the wetting fluid may be scraped in one direction by a scraper to scrape the wetting fluid from one end of the fabric to the other end of the fabric. In particular, the scraper may be a scraper blade or a scraper blade.

Optionally, in some embodiments, the steps S101 to S105 may be manually controlled by a user, in other embodiments, the spraying apparatus includes a first controller, and the wetting fluid nozzle and the first image capturing device are communicatively connected to the first controller, and the steps S101 to S105 are performed by the first controller. For example, the spray range may be adjusted manually or automatically by the spray equipment. Specifically, the spraying device can acquire an image of a target pattern to be printed, adjust a spraying area of the spraying device according to the image data of the target pattern, and spray the wetting liquid only on the area of the fabric where the target pattern is to be printed. In some embodiments, the spraying equipment further comprises a human-computer interaction interface, the spraying range can be set by manually inputting position parameters, size parameters and/or shapes of the spraying area, and the spraying equipment adjusts the position and the spraying range of the spray head according to the input parameters. The first controller can determine the color system of the fabric according to the image shot by the first image acquisition device and control the scraper to uniformly scrape the wetting liquid on the surface of the fabric.

And S12, the printing device determines a printing mode according to the color system of the fabric and prints a target pattern on the wetting liquid layer based on the printing mode.

In this embodiment, after the web is sprayed with the wetting fluid, the web is removed from the spraying apparatus and transferred to a platen of a printing apparatus for printing a target pattern. Because the spraying equipment and the printing equipment are mutually independent, the electronic elements of the printing equipment can be prevented from being corroded by water mist formed by the wetting liquid, the equipment cannot be damaged, and normal production and processing work is not influenced.

The printing equipment in this embodiment includes digital printing machine, and the inkjet printing technology that digital printing machine adopted is higher than traditional printing technology far away to the requirement of environment. In general, digital printing is suitably carried out at an ambient temperature of 20 to 30 ℃, an ambient humidity of 50 to 80%, and a compression pressure of 0.6 to 0.8 MPa. The normal operation of the equipment can be influenced by too high ambient temperature, and the viscosity of the ink can be increased by too low ambient temperature, so that the ink printing is not smooth enough. Too high ambient humidity tends to cause pattern bleeding, while too low ambient humidity tends to cause nozzle clogging.

The fabric in the embodiment of the present invention includes clothing, ties, scarves, wall cloth, sofa cloth, tablecloths, bed sheets, and the like, and the fabric may be woven from one or more of cotton fibers, hemp fibers, silk, chemical fibers, and the like.

According to the difference of the solvent, the ink for ink-jet printing can be divided into water-based ink and oil-based ink, the ink in the embodiment of the present invention can be either water-based ink or oil-based ink, and the skilled person can select the ink according to the actual needs. Generally, different types of inks are suitable for fabrics made of different materials, for example, a reactive dye ink is suitable for pure cotton fabrics, a disperse dye ink is suitable for polyester fabrics, a cationic dye ink is suitable for acrylic fabrics, and a mixed ink of the reactive dye ink and the disperse dye ink is suitable for polyester and cotton blended fabrics.

The aqueous ink mainly uses water as a solvent, and is one of the most commonly used inks at present. Aqueous inks typically include colorants, solvents, surfactants, viscosity modifiers, PH modifiers, siccatives, and the like. The aqueous inks are classified into dye inks and pigment inks according to the difference of the colorant; the colorant molecules in the dye ink are dissolved in water, and the colorant molecules in the pigment ink are insoluble in water and uniformly dispersed in water. The wetting fluid in the embodiments of the present invention can physically or chemically interact with the colorant in the ink to increase the adhesive strength between the colorant and the wetting fluid, thereby improving the color fastness of the target pattern.

In some embodiments, when the ink is a dye ink, the wetting fluid may contain an anionic resin or a cationic resin, and when the wetting fluid contains a cationic resin, the colorant in the ink may be an anionic dye; accordingly, when the wetting fluid includes an anionic resin, the colorant in the ink may be a cationic dye; therefore, the chemical groups in the wetting liquid can react with the water-soluble ionic groups in the colorant molecules to generate water-insoluble precipitates, and in addition, the anion/cation resin in the wetting liquid can form a protective film on the surface of the dried target pattern, so that the light resistance and the water resistance of the target pattern are improved.

In other embodiments, when the ink is a pigmented ink, the resin in the fountain solution can disrupt the dispersion in the pigmented ink, causing the colorant dispersed in the water to agglomerate and settle, separating the colorant from the water. In addition, the fixing resin is polymerized to form a cross-linked network structure, so that the coloring agent is fixed on the surface of the fabric, and the bonding strength of the coloring agent on the fabric is improved. In this embodiment, after the target pattern is printed, the pigment ink is quickly locked by the wetting liquid, and the ink is prevented from diffusing to the periphery, so that the clear target pattern is formed in a new city.

The colors of the inks in the embodiment of the present invention include, but are not limited to, cyan (C), magenta (M), yellow (Y), and black (K), and the desired color is obtained by mixing and superimposing the dye inks of the four colors C, M, Y and K. Optionally, the color of the dye ink can also be sapphire blue, scarlet, fluorescent yellow, pearl blue, gold, silver and the like.

Since the color of the fabric can affect the final rendering effect of the target pattern, the printing device can acquire the color of the fabric before printing the target pattern, and then determine the color system of the fabric according to the color of the fabric. The printing equipment further comprises a second image acquisition device in communication connection with the second controller, and the printing equipment can specifically acquire the color of the fabric through the image of the fabric shot by the second image acquisition device and then determine the color system of the fabric according to the color of the fabric. For example, when the color of the fabric is white, light blue, light yellow, or the like, it is determined that the fabric belongs to the light color family. When the color of the fabric is big red, black, blue or dark purple, the fabric is determined to belong to a dark color system.

Further, the printing device can comprise a second controller, and a white ink nozzle and a color ink nozzle which are in communication connection with the second controller, wherein the white ink nozzle is used for spraying and printing white ink, and the color ink nozzle is used for spraying and printing color ink. When the fabric is in a dark color system, the printing mode of the printing equipment is determined to be the first mode, and at the moment, the second controller controls the white ink nozzle and the color ink nozzle to successively jet and print the white ink and the color ink on the wetting liquid layer to form a target pattern according to the mode of firstly jetting and printing the white ink and then jetting and printing the color ink. When the fabric is in a light color system, the printing mode of the printing equipment is determined to be a second mode, at the moment, the white ink nozzle does not work, and the second controller controls the color ink nozzle to directly spray and print color ink on the wetting liquid layer to form patterns.

For example, when the fabric itself is bright red and the target pattern to be printed is yellow, if the yellow ink is directly sprayed on the fabric to form the target pattern, the target pattern which finally appears orange is caused by the superposition of the color of the yellow ink and the color of the bright red fabric. In this embodiment, the second controller may determine that the bright red fabric belongs to a dark color system according to the image captured by the second image capturing device, control the white ink nozzle to print white ink, form a white ground color on the fabric surface through the white ink, and print a color ink on the white ink to form a pattern.

In some embodiments, when the color system of the printing area on the fabric is only one, the printing mode of the printing apparatus is the first mode or the second mode. In other embodiments, when the color system of the printed area on the fabric includes both a dark color system and a light color system, the printing apparatus may print alternately using the first mode and the second mode when printing the target pattern, or directly print all by default in the first mode. The second controller can specifically acquire the color system of the fabric in the printing area right below the white ink nozzle and/or the color ink nozzle in real time through the image shot by the second image acquisition device.

For example, in some embodiments, the white ink nozzle and the color ink nozzle of the printing device may be arranged side by side, in a case where the color of the textile printing area itself includes both black and white, after the white ink nozzle and/or the color ink nozzle enters the printing area, the second controller may obtain the color of the printing area directly below the white ink nozzle and/or the color ink nozzle in real time according to the image captured by the second image capturing device, when the color directly below the white ink nozzle and/or the color ink nozzle is black, the printing mode of the printing apparatus is the first mode, and when the color directly below the white ink nozzle and/or the color ink nozzle is white, the second controller adjusts the printing mode of the printing apparatus to the second mode.

Specifically, the white ink head and the color ink head each include a plurality of orifices, and the second controller of the printing apparatus may control some of the orifices to eject ink and some of the orifices to not eject ink according to the image data to form the pattern on the fabric. The second controller can acquire an image of a target image-text to be printed, perform rasterization data processing on the image of the target image-text to be printed, and set corresponding image data parameters according to nozzle parameters of the white ink nozzle and/or the color ink nozzle, wherein the nozzle parameters include the number of the first nozzles. For example, the length of an image data packet after rasterization image processing is directly related to the number of the nozzles, the image data packet is a series of data including image information, each bit of data corresponds to each nozzle, and each bit of data is represented by 0 or 1; when the data is 0, it indicates that the corresponding nozzle does not eject ink, and when the data is 1, it indicates that the corresponding nozzle ejects ink. Accordingly, the second controller may be capable of controlling the white ink head and/or the color ink head to jet print the target pattern according to the image data.

In some embodiments, the inkjet printing method further comprises the steps of:

s13, drying the wetting liquid layer and the target pattern on the fabric, wherein the drying temperature is 150-160 ℃, and the drying time is 7-9 minutes.

Because the target image-text formed by the ink sprayed on the wetting liquid is easy to shift under the condition of no drying, and the final presentation effect of the target image-text is influenced, after the target image-text is printed, the wetting liquid and the target image-text need to be dried, the drying temperature is 150-160 ℃, and the drying time is 7-9 minutes. Specifically, the fabric with the printed target pattern can be placed on a conveyor belt of a tunnel furnace with the surface upward, and the fabric is dried; wherein the conveyer belt is of a net structure, and the conveying amplitude of the conveyer belt is controlled to be 1-3 mm.

The embodiment of the invention provides an ink-jet printing method, which comprises the steps of spraying a layer of wetting liquid on the surface of a fabric by adopting spraying equipment to form a wetting liquid layer, then determining a printing mode by using printing equipment according to the color system of the fabric, and printing a target pattern on the wetting liquid layer. Since the dampening solution is not dried prior to printing the target pattern, the areas of the fabric having the printed pattern feel softer and more air permeable. In addition, the spraying equipment and the printing equipment are two independent equipment, so that the wetting liquid mist formed in the process of spraying the wetting liquid by the spraying equipment cannot corrode electronic components of the printing equipment.
