[Industrial use]

The present invention relates to a three-dimensional etching method of the fabric, and to a fabric produced therefrom, and more particularly to a three-dimensional etching method capable of forming a variety of textures and patterns on the fabric, and a fabric produced therefrom.

[Private Technology]

In general, pile fabrics are also referred to as a type of fabric with a hair on one side, such as fur.

Of course, it is also used as a vehicle interior or building interior materials.

Except for the method of uniformly processing the length of the pile, the pile-like fabric has a shape or a pattern of the pile itself, which is only flat, and conventionally, a method of inserting a line having a constant depth through etching is used. The pile fabric and the etched fabric were processed into a pattern like a pattern by using the lining or the outer lining of a garment such as a coat.

However, this processing method is to raise a part of the pile to the original surface, and then cut the raised pile, it is difficult to form a pattern of a complex shape, there is a disadvantage that there is no three-dimensional impression at all.

In addition, a method of forming a pattern on the surface of the fabric is known as a surface etching method of a pile fabric using an etching aid, but there is a disadvantage that it is difficult to express a three-dimensional effect by a general planar etching method.

The present invention is to solve the above problems, it is an object of the present invention to provide a three-dimensional etching method for showing a three-dimensional three-dimensional texture in the fabric.

Another object of the present invention is to provide a fabric produced by the etching method.

In order to achieve the above object, the present invention etches the surface of the fabric using at least two screens and etching aids having different patterns, and adjusts the pore size of the screen pattern, or the viscosity of the etching aids, By adjusting the penetration depth, the present invention provides a three-dimensional etching method of fabric.

The present invention also provides a fabric fabricated by the above method, in which a three-dimensional etching pattern is formed having a gradient of etching depth.

Hereinafter, the present invention will be described in more detail.

Conventional fabric etching process forms a two-dimensional pattern having a cross section as shown in Figure 1 using a patterned screen. However, in the etching method of the present invention, the surface of the fabric is etched using at least two screens having different patterns and etching aids, and the etching depth is adjusted by changing the pore size of the screen pattern or the viscosity of the etching aids. By using the method, a three-dimensional pattern having a gradient of etching depth is formed on the surface of the fabric as shown in FIG. 2.

Specifically, the etching method of the present invention comprises the steps of: positioning a screen patterned on the fabric; And at least two etching processes including applying an etching agent on the screen, and in each etching process, the etching depth may be changed by changing the pore size of the screen pattern or the viscosity of the etching agent. .

The screen may be used by arbitrarily manufacturing a screen having a pattern of various forms according to the type of the three-dimensional pattern to be formed on the fabric, using a screen having a different pore size and pattern according to the desired etching depth of the fabric, or The depth of etching is controlled by using etching agents having different viscosities on screens having different patterns with the same pore diameter.

At this time, it is preferable that each pattern of the various types of screens are formed to be continuously connected to each other, or some of the patterns are overlapped so that the etching depth of the fabric can be continuously controlled. Part of the overlapping pattern is a continuous etching, so the depth of etching is partially deepened. The larger the amount of etching aids passing through the pattern on the screen, the deeper the etching is done, and the smaller the amount of etching aids, the deeper the etching. Lowers.

3 to 6 is a schematic diagram showing an example of continuously adjusting the etching depth of the fabric by forming a screen so that some of each pattern overlaps. FIG. 3 is a schematic diagram of a screen (FIG. 3A) and a fabric (FIGS. 3B and 3C) without a pattern formed thereon, and FIG. 4 is a narrow screen (FIG. 4A) and a fabric etched using the screen (FIG. 4B). 4c is a schematic diagram of a wider screen (FIG. 5a) and a fabric etched continuously using the screen (FIGS. 5b, 5c), and FIG. 6 is wider than FIG. 6A and 6C are schematic views of fabrics continuously etched using the screens (FIGS. 6B and 6C).

The pore diameter of the pattern of the screen may be represented by a mesh defined as the number of through holes included in the area of each inch of the width and length of the net formed finely in the screen pattern, and the mesh is # 40 to # 150 It is preferable for the fairness of an etching, and it is more preferable that they are # 60- # 130.

The larger the mesh value of the pore size of the screen pattern is, the more difficult the penetration of the etching agent is, so that the etch depth of the fabric is lower. The smaller the mesh value of the pore size is, the easier the penetration of the etching agent is, and the etching depth of the fabric is deeper.

In addition, the etching agent may be selected from among conventional etching agents, it is preferable to select an appropriate etching agent according to the type of fabric used.

It is preferable for the fairness that the etching agent used in the present invention has a viscosity of 1000 to 10000 cps. The higher the viscosity of the etching agent, the smaller the amount of etching agent passing through the pattern of the screen and the lower the depth to be etched. The lower the viscosity, the greater the amount of the agent penetrating into the fabric and the deeper the etching depth.

In order to enhance the etching effect of the fabric, the pH of the etching aid is preferably 11 or more, and in order to prevent damage to the fabric due to excessive etching, the pH is preferably 13 or less. However, the pH of the etching agent is only a range for showing the most preferable effect, it is not necessarily limited to the above range.

In addition, the etching agent preferably comprises at least one alkali compound such as sodium hydroxide or potassium hydroxide, and more preferably 10 to 50% by weight based on the total weight of the agent.

The method of applying the etching agent is not particularly limited since it is the same as the etching process of the conventional fabric, but it is preferable to use a method of applying the etching agent while pushing the etching agent using a squeeze roll capable of adjusting the pressure. At this time, the size of the squeeze roll used may be selected according to the process conditions, it is preferable to apply a pressure of 0.1 to 10 kgf / cm ² using a roll having a particle diameter of 10 to 50 mm, the coating process is etching You can repeat this several times, depending on the depth of the pattern you want.

Fabrics to which the etching method can be applied include artificial leather, non-woven fabrics, or pile fabrics, preferably selected from the group consisting of double laselle, tricot, and mocket among the fabrics of the piles.

In addition, the fabric may be any one made of fibers which can be etched by an etching agent, and in the group consisting of nylon fibers, polyester fibers, polyurethane fibers, polyacrylonitrile fibers, polyolefin fibers, and cellulose fibers. It is preferable to include one or more selected, and it is more preferable to include nylon fiber, polyester fiber, or a mixture thereof among these.

The etching method of the present invention may further comprise a dyeing process of a specific pattern at an appropriate stage as needed. The dyeing process may proceed with a method of using a general dyeing agent rather than an etching agent on the screen on which the pattern is formed, and in this way it is possible to further enhance the three-dimensional appearance of the fabric.

The fabric produced by the above method is formed with a three-dimensional etching pattern having a gradient of the depth of etching, excellent in aesthetics and feel can be used for applications such as high-end interior materials for automobiles, building interior materials and the like.
