Description

Digital textile printing method {DIGITAL TEXTILE PRINTING METHOD}

The present invention relates to a digital textile printing method, and more particularly, to the provision of a new digital textile printing method capable of maximizing work efficiency by enabling digital printing through transfer regardless of the material (type) of the fabric. .

In general, in the case of digital printing, a pattern is printed directly on the surface of the fabric using a digital printer, and the pattern on the transfer paper is printed on the transfer paper, and then the fabric and the transfer paper are combined and heated and compressed at a predetermined temperature to make the pattern on the transfer paper. This is done in a way that is transferred to and printed.

In the prior art, various technologies for digital printing have been developed and used, and representative examples are as follows through the patent literature,

None.

In the case of Patent Document 1 among the prior art as described above, a plurality of heater members are installed in several places of the digital printer to sequentially heat and dry the transfer ink printed on the fabric, and at the same time move it horizontally to 600 degrees at 180 degrees. A thermal transfer device that emits hot air between the figures is installed to directly heat and transfer the transfer ink printed on the fabric. It is to provide a thermal transfer paper including a transparent adhesive layer to be formed by the actual printing output pattern color layer.

In the case of the prior art as described above, the transfer paper is printed with a gravure printing machine, but it is impossible to print a pattern close to the real thing like a photograph. As a device for printing because the transfer paper passes in close contact with the rotating cylinder after rotation, it is difficult to print a precise pattern like a photograph because the pattern is formed in unevenness on the copper plate and printing is applied to the unevenness.

And, after attaching the transfer paper to the textile paper, the pattern is printed in a way that heat is applied while being compressed by putting it in a compressor. there will be no

Also, in the case of polyester among textile papers, digital transfer is possible when transfer paper is combined and heat-pressed. do.

In order to solve this problem, in the case of fabrics other than polyester, a number of processes such as steam heating, washing, and drying are required for digital printing, so competitiveness due to excessive production costs is weakened. There are several problems, such as finding

Accordingly, in the present invention, as invented to solve the above problems, a preparation step (S100) of preparing the material as a whole to perform digital textile printing;

A supply step of supplying the prepared material to the digital printer (S200) and;

a digital printing step (S300) of operating a digital printer to print a desired pattern on the fabric;

A processing step (S400) of standardizing and arranging irregularly exposed edges after digital printing is completed;

Characterized in that it comprises a completion step (S500) of commercialization through the post-work of winding and packaging in the finished state;

The transfer state of the fabric surface is clear, various patterns can be expressed, and digital printing is possible regardless of the type of fabric.

The present invention enables digital printing work regardless of the type of fabric by allowing the pattern of the transfer paper to be transferred by heat pressure to the fabric other than polyester, such as cotton, silk, hemp, leather, and synthetic leather, so that it can be accurately expressed. It has the effect of obtaining efficient work and high-quality fabric at low cost.

The present invention has the effect of increasing work efficiency by interposing a transfer mediating fabric to be able to express a pattern by laminating a transfer paper to a fabric other than polyester so that the mediating fabric is not separated and laminated with the transfer target fabric after transfer.

Since the present invention uses a medium fabric, it can be transferred to a yarn-dyed fabric, and there is no white phenomenon due to printing on the back side of the fabric after the pattern is completed.

In the digital textile printing method to which the technology of the present invention is applied, digital transfer printing is performed on materials such as cotton or silk, hemp, leather, synthetic leather, etc. excluding polyester fabric paper to increase work efficiency and It is characterized by improving the quality and allowing various uses.

This digital textile printing method includes a preparation step (S100) of preparing the material as a whole to perform digital textile printing, a supplying step (S200) of supplying the prepared material to a digital printer, and operating the digital printer for the purpose of the fabric A digital printing step (S300) of transferring and printing the desired pattern, a processing step (S400) of standardizing and arranging the irregularly exposed edges after digital printing is completed (S400), and winding and packaging in the finished state It consists of a completion step (S500) of commercialization through post-work.

In the preparation step (S100), the fabric preparation process (S110) of preparing the fabric 110 for digital transfer printing in a roll type, and the well-known transfer paper 120 expressing the design to be transferred to the fabric 110 ) to prepare a roll type transfer paper preparation process (S120), and each fabric preparation process (S130) for preparing each fabric 130 so that the design of the transfer paper 120 can be smoothly transferred and expressed on the fabric 110 include

The fabric 110 prepared in the fabric preparation process (S110) can be any fabric to be used except for the polyester fabric that can be directly digitally printed, so you can select the fabric you need from among many types of fabrics.

In the intermediate fabric preparation process (S130), an intermediate fabric 130 made of a white polyester material having a thin thickness without dense tissue is prepared, which is larger than the width and length of the fabric 110 and the transfer paper 120 . It is good to have it so that there is no untransferred part in the digital printing process.

When supplied to the fabric 110 and a digital printer on the back side of the intermediate fabric 130, the adhesive force at a temperature before and after about 150° C. so that it can be laminated by the heat generated by the pressure roller and heater that supply and adhere in the digital transfer printing process. Prepared by applying a well-known thermal adhesive 140 that generates

In the supply step (S200), the fabric 110, the transfer paper 120, and the intermediate fabric 130 are prepared in a roll type and fed together by a digital printer, and the intermediate fabric 130 on the fabric 110 is supplied. position, so that the transfer paper 120 is positioned on the intermediate fabric 130 .

In the digital printing step (S300), when the intermediate fabric 130 is positioned on the fabric 110 and the transfer paper 120 is positioned on the fabric 130 and supplied to the digital printing machine in a laminated state, while passing through the digital printer As the pressurized and heated, the intermediate fabric 130 on the fabric 110 is firmly laminated by the thermal adhesive 140 so as not to be separated.

And, the pattern of the transfer paper 120 located on the intermediate fabric 130 is transferred to the intermediate fabric 130 and expressed, and since the transfer is not made directly to the fabric 110, the fabric 110 is dyed in various colors. Even when supplied, not only the transfer pattern is clearly expressed, but also the back side of the fabric 110 is whitened after the transfer is completed, thereby avoiding the problem of not being clean.

In the processing step (S400), each fabric 130 is provided with a size larger than the fabric 110 and the transfer paper 120 in consideration of the non-transfer of the pattern, so after the digital transfer printing is completed, the outer side of the fabric 110 Since the intermediate fabric 130 is exposed and becomes a state that spoils the aesthetics, it is wound in a roll type while going through the process of cutting the edges evenly.
