Technical Field

[0001] The invention relates to the technical field of textiles, and in particular to a three-layer fabric with digital positioning printing and a preparation method thereof. Background Art

[0002] As people's quality of life continues to improve, the public's demand for fabrics has become more diverse. In order to achieve a variety of colors and patterns on fabrics, it is usually necessary to use a variety of yarns of different materials during the front-end weaving and combine different types of dyes during the back-end dyeing and finishing. However, the weaving process and dyeing and finishing process used in this method are complex, have low timeliness, and have color limitations. In order to achieve a variety of colors during dyeing, a large amount of dyes and water are consumed, which is not green and environmentally friendly. In order to solve the above problems, researchers have developed a printing process.

[0003] In the traditional printing process, the grey cloth is sizing, and then the dye is attached to the fabric by spray printing or transfer printing, and then the finished printed fabric is obtained through steaming, washing, shaping and softening. For example, the Chinese invention patent with application number 201711231480.2 discloses a method for printing plush fabrics, which is realized by washing, printing, steaming and fixing, and shaping treatment in sequence. This type of printing technology has many processes, long cycles, and poor timeliness. Summary of the invention

[0006] Another technical solution adopted by the present invention is: a three-layer fabric with digital positioning printing prepared by the above preparation method.

[0007] The beneficial effects of the present invention are as follows: the preparation method of the present invention combines intelligent image recognition to perform precise digital positioning printing on a three-layer structured fabric, and sets the surface layer of the fabric to a mesh jacquard structure so that the bottom layer color can pass through the surface layer, thereby obtaining a multi-color fabric with a variety of color changes, which has the advantages of energy saving, environmental protection, and fast timeliness.

[0013] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0014] A method for preparing a three-layer fabric for digital positioning printing comprises weaving a three-layer fabric comprising a surface layer, a middle layer and a bottom layer with yarn, wherein the surface layer is a mesh jacquard structure; preheating the three-layer fabric, and then performing digital printing on the surface layer.

[0015] From the above description, it can be seen that the beneficial effect of the present invention is that the present invention combines intelligent image recognition to accurately digitally position print on the three-layer fabric, which has the advantages of simple operation, energy saving, environmental protection, and fast timeliness. In addition, because the surface layer is a mesh jacquard structure, the bottom layer color can be transmitted, the three-dimensional layering is strong, and the fabric color changes are diverse.

[0016] Furthermore, the bottom layer is a plain weave or a mesh weave.

[0017] From the above description, it can be seen that the base tissue is selected according to the breathability requirements.

[0018] Furthermore, the mesh height of the surface layer is greater than 1 mm.

[0019] From the above description, it can be seen that the mesh height of the surface layer is greater than 1 mm, which can improve the accuracy of digital printing.

[0020] Furthermore, the surface layer is woven with the first yarn, the bottom layer is woven with the second yarn, and the middle layer is woven with the first yarn or the second yarn.

[0021] Furthermore, the first yarn and the second yarn are post-dyed yarns and are made of different materials.

[0022] Furthermore, the first yarn is a post-dyed yarn of nylon, and the second yarn is a post-dyed yarn of polyester. Furthermore, the first yarn is a post-dyed yarn, and the second yarn is a colored yarn.

[0023] From the above description, it can be seen that in traditional printing technology, the bottom layer of the three-layer fabric is usually white. Since the printing dye of the surface layer cannot penetrate through the middle layer to the bottom layer, the white bottom layer will be exposed through the mesh and gaps of the surface, affecting the overall printing effect. In the present invention, the back-dyed yarn or colored yarn is selected as the bottom yarn, so that the bottom layer presents a colored effect, solves the problem of white leakage in printing, and makes the overall printing effect of the fabric better and more three-dimensional.

[0024] Furthermore, the surface layer is white.

[0025] From the above description, it can be seen that the surface layer is white, which can better present the color effect of the printing.

[0026] Furthermore, the middle layer is a double needle bed loop structure.

[0027] From the above description, it can be seen that the middle layer is a double needle bed loop structure to connect the surface layer and the bottom layer.

[0028] Furthermore, digital printing includes fabric information collection processing, printing analysis processing and digital printing processing performed in sequence.

[0029] From the above description, we can know that fabric information collection and processing, that is, collecting basic information such as target fabric specifications and components, and conducting a hydrophilicity test on the surface to be printed on the target fabric. Printing analysis and processing, according to the results of the hydrophilicity test on the surface to be printed, preheat the current fabric; at the same time, adjust the printing paste prescription according to the printing image file. Digital printing processing, that is, printing the target fabric in combination with the printing analysis results.

[0030] Digital printing has a high degree of automation, simple operation and can reduce manpower consumption.

[0031] Furthermore, when the surface layer is 100% polyester, disperse dyes are selected as dyes for digital printing.

[0032] Furthermore, the height of the printing is less than or equal to 5 mm.

[0033] From the above description, it can be seen that the height of the printing is less than or equal to 5 mm, and the printing is not easy to fall off.

[0034] Another technical solution adopted by the present invention is: a three-layer fabric with digital positioning printing prepared by the above preparation method.

[0035] It can be seen from the above description that the three-layer fabric of the present invention has a strong three-dimensional layering effect and a variety of fabric colors.
