Description

{Textile Printing Method}

The present invention relates to a method of printing a dense color fabric, and more particularly, to a method of printing a dense color fabric in which color development is facilitated without forming a thick printing layer on a dense color fabric.

Textile printing has been used for a long time as dyeing technique which can dye various colors and images by coloring dye such as dye or pigment on the fabric in whole or in part and typically has dye printing and pigment printing .

Depending on what fiber is made of the object, dye printing is performed by selecting a dye suitable for coloring the fiber with the necessary fastness and color, boiling it with a paste, and appropriately putting it in a viscous liquid, It is mixed with a medicine for use and mixed well (it is said that the thing which is made so as to be printed is printed), and it is imprinted on the fiber water by a roller which is an intaglio- After that, dry, steam (heat), wash to make pattern appear.

Pigment resin printing is made by printing paste with pigment synthetic resin (initial condensation product), solvent, water etc., and it is imprinted on the fiber material to be printed with a stamping roller or screen, lightly dried, (Dry heat).

However, in such a conventional printing method, when the fabric is bright, the color is properly developed, but when the fabric is dark, when the fabric is printed, the fabric itself is deeply colored. It did not have the desired color. Therefore, in the case of a dark color fabric, the surface of the fabric is usually printed about three times to form a thick printing layer on the fabric, so that the printed surface has a desired color without being affected by the color of the dark color fabric. However, if the printing layer is formed thick as described above, since only the printed area becomes thicker on the fabric, not only the touch is not good but also the thick printed printing layer becomes poor in air permeability, there was.

As a background of the present invention, there is a patent registration No. 1183025 entitled " Method for printing a garment fabric and a fabric for a garment printed thereon "(Patent Document 1). In the background art, a transfer sheet printing step (S1) of printing a digital still image having a portion which is not printed on a part using a inkjet plotter, with a dye ink on a transfer sheet; A sublimation transferring and dyeing step of placing the printed surface of the transfer sheet on which the real image has been printed on the surface of the raw material and pressing the transfer paper and the raw paper with a high temperature roller to dye the printed portion of the transfer paper onto the sublimation transfer, (S2); A first printing step (S3) of printing an undried portion of the fabric corresponding to an unprinted portion of the transfer paper with a heat-sensitive discoloration dye; A second printing step (S4) for re-printing the pattern with the thermal dyeing dye on the upper surface of the portion of the fabric which is printed with the thermosensitive coloring dye; The present invention relates to a printing method for a garment fabric.

However, the above-mentioned background art has a problem that the fabric itself can not be applied to various fabrics since the fabric itself is formed by a transfer paper printing, a dyeing, a primary printing, and a secondary printing process, and in particular, there was. In addition, if the printing layer is formed thick as described above, since only the printed area is thickened on the fabric, the printed surface is not good, and the printed surface of the thick printing layer is poor in air permeability, There was a problem.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate exemplary embodiments of the invention and, together with the description, serve to explain the principles of the invention, Shall not be construed as limiting.
Fig. 1 is a flowchart showing a first embodiment of a method for printing a dark color fabric according to the present invention in order.
Fig. 2 is a flowchart showing a second embodiment of the method for printing a dark color fabric according to the present invention in order.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto.

Hereinafter, the technical structure of the present invention will be described in detail with reference to the preferred embodiments.

The present invention relates to a method for printing a dense color fabric, which makes color development easy without forming a thick printing layer on a dark color fabric.

In the first embodiment of the present invention, the dark color fabric is subjected to a process of flaming and printing to print a dark color fabric, and each process is subjected to a drying process, so that a pattern can be formed clearly without forming a printing layer thick on a dark color fabric Not only to facilitate the expression of color, but also to ensure long-lasting.

The first embodiment of the present invention will be described in detail as follows.

Fig. 1 is a flowchart showing a first embodiment of a method for printing a dark color fabric according to the present invention in order.

First, as shown in FIG. 1, a blowing agent is applied to a predetermined position of a dark color fabric (a).

The fabric is partially decolorized at a predetermined position of the fabric dyed with a dark color by a blowing agent so that the pattern is clear and the color is easily expressed in the printing step to be described later.

As described above, the blowing agent of the present invention removes dyes dyed in the fabric with a dark color by applying the oxidizing action and the reducing action of a chemical agent. As the blowing agent generally used for oxidative flushing, potassium chloride, potassium permanganate, Sodium hyaluronate, sodium hydrosulfite, sodium hydrosulfite, rongalite (sodium hydrosulfite), sodium hypochlorite, sodium hypochlorite, sodium hypochlorite and sodium hypochlorite. ). However, even when such a composition is used as a blowing agent, due to the characteristics of the components of the blowing agent contained therein and their mutual interactions, the kind and content of each component have a great influence on the outcome of the blowing.

Thus, by applying the blowing agent at a predetermined position of the dark color fabric to remove the dye from the fabric, the colored dye in the printing process described later is adhered to the color-removed fabric with the blowing agent, .

Next, in step (a), the portion of the fabric coated with the release agent is dried (b).

The blowing agent is allowed to decolor the dark color fabric, and the blowing agent applied to the fabric is dried to a constant weight without completely drying to facilitate the coloring of the printing agent in the printing step described later.

In particular, it is preferable that the drying of the blowing agent is performed so as to be 5 to 25 wt% of the solution of the blowing agent applied on the fabric.

When the blowing agent is dried to less than 5 wt%, the conventional dye of the fabric reacts with the blowing agent to form a coating layer on the corresponding portion. When the coating layer is formed, the dyeing agent is interrupted by the coating layer If it is dried more than 25wt%, the surface of the fabric coated with the blowing agent is so wet that the printing agent does not penetrate the fabric well, and the pattern is not clear and the color development may not be properly performed. do.

Thereafter, the area where the release agent of the fabric is applied is printed (c).

In the present invention, a printing agent is prepared by mixing a dye and a pigment, and in particular, a dye and a high mesh which express the hue of a printing material are used as a pigment to soften the printing region The pattern is clear and the color can be easily expressed.

The mixing ratio of the dye and the high mesh may be varied, and the weight ratio of the dye and the high mesh may preferably be 1: 0.5 to 2.

High mesh Binder used as pigment is a known product and is used for soft touch printing.

By the steps (a) and (b), the surface of the fabric is discolored and dried by the use of the blowing agent, so that the pattern is clear and the color is properly expressed.

Thereafter, the printed area of the fabric is dried (d).

If the subsequent thermal treatment step is carried out before the printed printing agent is dried, it should be dried to a constant weight without being completely dried, since the coated portion may be damaged or deformed.

In particular, it is preferable that the drying of the printing agent is performed so as to be 5 to 25 wt% of the printing agent solution applied to the fabric.

If the printing agent is dried to less than 5 wt%, the applied portion of the printing agent may be damaged or deformed, and if it exceeds 25 wt%, if the surface of the fabric coated with the printing agent is too wet to perform the subsequent heat treatment step, The applied portion may be damaged or deformed, the pattern may not be clear, and the color may not be properly displayed, thereby deteriorating the quality of the printing.

Since the moisture contained in the printing agent can degrade the surface quality during the heat treatment in the subsequent heat treatment step, the present invention can provide a method of drying the printing agent by a predetermined weight to prevent the decrease in the heat treatment efficiency in the subsequent step, The amount of the heat of vaporization from the printing agent is reduced to induce a rapid increase in the heat treatment temperature, thereby enhancing the heat treatment effect of the printing.

Finally, heat the fabric at 180 ~ 200 ℃ for 5 ~ 15 minutes (e).

The heat treatment is performed by various known methods such as steam jetting to ensure that the printing agent and the coating agent are more firmly fixed to the fabric. If the temperature does not reach 180 ° C or the time is less than 5 minutes, And when the heat treatment is performed at a temperature exceeding 200 ° C. or exceeding 15 minutes, there is a risk of damage to the printing region, so that the heat treatment should be performed under the above conditions.

In the first embodiment of the present invention, the processes of discharging and printing are separated, but the discharging and printing processes are simultaneously performed in the second embodiment of the present invention. At this time as well, the drying process is carried out so that the pattern is clear and the color is easily expressed without forming the printing layer thick on the dark color fabric, and it is made long lasting.

Fig. 2 is a flowchart showing a second embodiment of the method for printing a dark color fabric according to the present invention in order.

As shown in FIG. 2, the second embodiment of the present invention first applies a mixture containing a salt-forming agent and a dye to a predetermined position of a dark color fabric (A).

In this way, a mixture of a salt-forming agent and a dye is simultaneously used, so that dyeing by the dye is performed simultaneously with the discharge of the fabric.

The mixing ratio of the blowing agent and the dye can be differently applied according to the pattern or color expressed on the fabric. Unlike the first embodiment, since the separate pigment to be applied for printing can be omitted, the process becomes simple, Can be saved.

Thereafter, the portion of the fabric coated with the mixed agent is dried (B).

If the mixture is subjected to a subsequent heat treatment step before it is dried, it should be dried to a constant weight, as the applied portion may be damaged or deformed.

In particular, it is preferable that the mixture is dried so as to be 5 to 25 wt% of the mixed solution applied to the fabric.

If the mixed material is dried to less than 5 wt%, the portion to which the mixed material is applied may be damaged or deformed. If the mixed material is dried in excess of 25 wt%, if the surface of the material to which the mixed material is applied is too wet to perform the subsequent heat treatment step, The coated portion may be damaged or deformed, so that the pattern is not clear and the color development may not be properly performed, and the quality of the printing is greatly deteriorated.

Since the moisture contained in the mixed material may degrade the surface quality during the heat treatment in the subsequent heat treatment step, the present invention can provide a method of drying the mixed material at a constant weight to prevent a decrease in heat treatment efficiency in a subsequent process, It is possible to increase the heat treatment effect of the printing by reducing the amount of vaporization heat and inducing the rapid increase of the heat treatment temperature.

Finally, the fabric is heat treated at a temperature of 180 to 200 ° C for 5 to 15 minutes (C).

The heat treatment is performed by various known methods such as steam jetting to ensure that the textile material is more firmly fixed to the fabric. If the temperature does not reach 180 ° C or the time is less than 5 minutes, Water dropout phenomenon occurs, and when the heat treatment is performed at a temperature exceeding 200 ° C or exceeding 15 minutes, there is a fear of damage to the printed region, so that the heat treatment must be performed under the above conditions

The method of printing a dense color fabric according to the present invention as described above is to print on a dark color fabric but undergo a drying process so that the pattern is clear and the color is easily expressed without forming a thick printing layer on a dark color fabric There is a very useful effect to ensure long lasting.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the above teachings. will be. The invention is not limited by these variations and modifications, but is limited only by the claims appended hereto.
