Description

  The present invention relates to an ink jet textile printing method for printing an image on a cloth such as clothing, and more specifically, a processing liquid (bordering) having a function of improving image quality when printing an image on a cloth by ejecting recording ink from an ink jet head. The present invention relates to an ink jet textile printing method in which a liquid, a penetrating liquid, etc.) are applied to a fabric.

  Conventional textile printing, such as screen printing using a plate, has been performed. On the other hand, the ink jet textile recording method using an ink jet method is a non-plate and can depict gradation that is difficult with screen textile printing. In addition, the present invention has an excellent characteristic suitable for a small quantity and a wide variety of products, such that an efficient print process is possible even with a single fabric recording the same image.

  When ink jet recording is performed on a fabric, bleeding occurs. Therefore, the fabric is usually subjected to pretreatment for the purpose of preventing bleeding and improving the fixability of the colorant to the fabric. Specifically, the fabric is preliminarily dipped or coated in an aqueous solution containing an anti-bleeding agent, a fixability improving agent, and the like, and then dried to perform image formation.

  Such a fabric pretreatment step is a necessary step in textile printing, but the conventional pretreatment method has the following problems.

1) It takes time and man-hours for pretreatment,
2) Even if pre-treatment is performed in advance, the function deteriorates with the passage of time, so the pre-treated fabric cannot be stored for a long period of time.
3) Since pre-treatment is performed on the entire surface of the fabric including a portion where no image is formed, contamination (stain) may occur on a white background which is an unimaged portion.

  For each of the above problems, an ink jet textile printing method has been proposed in which a pretreatment for a fabric is performed by an ink jet method (see, for example, Patent Document 1). However, although the types and methods of pre-processing have conditions suitable for each design, the necessity and the realization means are not fully studied at present. In particular, the pre-processing performed prior to image recording by the ink jet method is performed in advance using one type of pre-processing liquid on the entire surface, and is appropriately selected according to the pattern in the image and optimal for each part. There was no idea of pre-processing.

By preventing penetration of the penetrating liquid into the image portion and preventing bleeding at the boundary portion of the image to be formed, it is possible to emphasize clearly.

  For example, even when a thick fabric such as a towel is used, an undyed portion is generated not only on the surface portion but also on the deep portion by applying the permeating liquid to the background dyed portion of the border image. Fabric that is dyed firmly in the recording ink can be obtained without irritating, and the penetrating liquid and recording ink used in the ground dyeing part can be prevented from penetrating into the border. Thus, a clear image can be formed.

  According to a second aspect of the present invention, there is provided a border liquid, a recording ink, a bleeding preventing liquid having a function of preventing bleeding of the recording ink on the cloth, and a penetrating liquid that promotes the penetration of the recording ink into the cloth.

An ink-jet printing method characterized in that an image is formed.

  As a result, according to the design of the image to be recorded on the fabric, the bordering liquid, the bleeding preventing liquid, and the penetrating liquid are selected as needed and applied to the cloth, and at least the recording ink is applied to the penetrating liquid applying section and the bleeding preventing liquid applying section. It has been found that an ink-jet textile printing method can be provided by which a high-quality edge image can be obtained with no blurring and with no occurrence of flickering.

  By such a printing method, in the design to be recorded, the background dyed portion and the image portion are clearly separated by the border portion, and the recording ink or penetrating liquid applied to the background dye portion is blocked by the border liquid. Intruding into the image portion. In addition, after applying the anti-bleeding liquid to the image portion inside the border portion, an image having a pattern portion is provided by applying recording inks having different hues and densities to form a finer pattern on the image portion. Even in the portion, there is no occurrence of bleeding, and a high-quality image can be obtained. This is because the recording ink in the background dyed portion is blocked and does not penetrate inside the border, and the recording ink applied to draw a pattern in the image portion inside the border is unnecessarily diffused by the anti-bleeding liquid. This is because the pattern can be formed with an appropriate dot diameter at the landed spot.

  The fabric P conveyed from the right direction is sandwiched between the nip roll 4 and the adhesive belt 1 and fixed to the adhesive belt 1. Next, the edging liquid is applied from the head aH to the region A of the fabric P (A portion in FIGS. 1 and 2). Further, after applying the bleeding prevention liquid to the region B (B portion in FIGS. 1 and 2) and the region C (C portion in FIG. 1) of the fabric P from the head bH, the temperature controllable wind or hot air is blown. Means 5, specifically, a hot plate 8 a as a means for heating the fabric from the back side by means of drying means 5 for providing warm air provided with a fan 6 and a heating element 7 and applying hot air inside the conveyor belt 1. Is used to sufficiently dry the edging liquid and the bleeding preventing liquid applied on the fabric P. Here, while the fabric is heated by the hot plate 8b disposed so as to cover the lower part of the recording ink head dH, the recording ink is applied to the fabric from the head dH to form a clear image with bleeding prevented.

  When recording a pattern such as part C on the inner side of part B in FIG. 1, after applying a bleeding prevention liquid and drying, recording inks of different hues are applied to the fabric from the head dH, and bleeding is performed. It is possible to form a clear pattern that prevents the above.

  Furthermore, the D part in FIGS. 1 and 2 is mainly for the purpose of dyeing without flickering as a ground dyeing part. Specifically, the fabric P conveyed from the right direction is adhered to the nip roll 4. And then fixed to the adhesive belt 1. Then, the penetrating liquid is applied to the region D (FIGS. 1 and 2) by the head cH, the recording ink is applied by the head dH, and the irritation occurs. No high quality image is formed.

  In the above, the order in which each ink, bordering liquid, penetrating liquid, and bleeding prevention liquid is applied to the fabric is not limited, but preferably the bordering liquid is first applied. Further, it is preferable to apply an application method in which a bleeding preventing liquid is applied next to the edging liquid, a drying means is applied, a penetrating liquid is applied, and then a recording ink is applied.

  In the above, “application of bordering liquid → application of anti-bleeding liquid → drying means → application of penetrating liquid → application of recording ink having a desired hue to each area in the design (areas A, B, C and D in FIG. 1) Although a preferred order step of “giving” has been described, the present invention is not limited to this order. In particular, the permeation liquid application process and the recording ink application process may be reversed.

  In any case, it is preferable to continuously apply the penetrating liquid and the recording ink so that the recording ink is applied before the penetrating liquid dries to exert the effect of the penetrating liquid.

  By applying the rimming liquid, bleeding prevention liquid and penetrating liquid to each desired pattern portion by the above-described method by the ink jet method, and applying the recording ink at a predetermined position, the penetrating liquid diffuses into the pattern portion. This suppresses the phenomenon of bleeding and allows a clear image free of bleeding to be formed on a desired portion of the fabric to which the colorant ink is applied without irritation.

  FIG. 4 is a partial schematic view showing another example of the ink jet textile printing apparatus.

  The ink jet textile recording apparatus shown in FIG. 4 is obtained by removing drying means by applying warm air in the ink jet textile recording apparatus shown in FIG.
