Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a print-coated cloth coating film which is applied to a colored cloth. In particular, it relates to a fabric coating film having a polyurethane resin layer. The present invention also relates to an emblem made of such a film for covering a fabric and attached to clothing such as sportswear and children's clothing.

[0002]

2. Description of the Related Art Textiles are covered with a plastic film or a plastic film subjected to a printing process in order to impart waterproofness, air barrier property, or a pattern. In particular, a polyurethane resin film is preferably used because it has excellent abrasion resistance, flexibility and the like, and moreover, it gives a good texture even when it is coated on a fabric.

Further, an emblem or the like, which is formed of these films for covering cloth and has a vivid color pattern, is attached to clothing such as sportswear and children's clothing.

However, when the cloth to be coated is colored, the dye contained in the cloth migrates to the film and reaches the printing layer after a lapse of time, causing the printed pattern to be discolored and unsightly. Especially when heated, the tendency was remarkable. For example, when sportswear or children's clothing to which the emblem is attached is washed and then dried with a hot air dryer or the like, migration of the dye is further promoted, and the emblem pattern is discolored and unsightly.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a fabric coating film having a print pattern to be applied to a colored fabric is heated particularly when the time has passed after being applied to the fabric. At the same time, it is an object of the present invention to provide a film for covering a fabric in which the printed pattern does not change color due to the migration of the dye contained in the fabric. In particular, it is intended to provide a fabric coating film having these properties by using a polyurethane resin layer having excellent abrasion resistance and flexibility. Another object of the present invention is to provide an emblem to be attached to clothing such as sportswear and children's clothing that does not cause discoloration of the printed pattern due to the passage of time and heating.

[0006]

The present invention has taken the following means in order to solve the above problems.

That is, the fabric coating film of the present invention is a laminated film comprising at least one ethylene-vinyl alcohol copolymer layer and at least one printed layer, and at least one of the laminated films. When the printing layer is not located on the surface and the printing layer is present on only one surface of the both surfaces of the laminated film, the surface on which the printing layer is not located and the printing layer closest to the surface At least one layer of ethylene-vinyl alcohol copolymer is provided between, or if one of the surfaces of the laminated film does not exist on either side of the laminated film and the printing layer closest to the surface. Position the coalescence layer. Preferably, at least one polyurethane resin layer is further laminated.

An emblem to be attached to clothes is made of the film for covering cloth. The ethylene-vinyl alcohol copolymer used in the present invention is not particularly limited, but one having an ethylene content of 47 mol% or less is suitable from the viewpoint of the discoloration preventing property of the printed pattern.

However, if the ethylene content is too low, the flexibility is poor and the texture of the fabric is deteriorated. Therefore, the ethylene content is preferably 25 mol% or more.

The printing layer in the present invention includes not only a printing ink layer which is conventionally applied to a plastic film, but also a vapor-deposited layer of aluminum or the like. The printing ink layer and the vapor deposition layer of aluminum or the like may be continuous, or another resin layer may be present between the printing ink layer and the vapor deposition layer of aluminum or the like.

Further, the polyurethane resin used in the present invention is not particularly limited, and all those which can be formed into a film can be mentioned. Preferably,
It is preferable that the film can be coextruded with an ethylene-vinyl alcohol copolymer or the like.

The film constitution of the film for covering fabric of the present invention is first subjected to a printing process because the purpose of the present invention is to prevent discoloration of the print pattern applied to the film. It is necessary.

Next, the fabric coating film of the present invention requires that at least one surface of the film is free of a printing layer. This is because, when the fabric coating film is coated on the fabric, it is necessary that the surface in contact with the fabric is not the printing surface. When the printing layer is located on the surface attached to the cloth, the dye contained in the cloth directly transfers to the printing layer and discolors the print pattern.

It should be noted that whether or not the surface on the side not in contact with the fabric is the printing layer is not limited in any way. That is, the surface not in contact with the fabric may or may not be the printed layer.

Further, when the printing layer is present only on one of the two surfaces, it is provided between the surface on which the printing layer is not located and the printing layer closest to the surface, or the printing layer is on both surfaces. If not present, it is necessary to place at least one ethylene-vinyl alcohol copolymer layer between either surface and the printing layer closest to the surface. This is because the ethylene-vinyl alcohol copolymer layer seems to prevent migration of the dye contained in the fabric, so that the layer between the surface in contact with the fabric and the printing layer closest to the surface is It is necessary to locate the ethylene-vinyl alcohol copolymer resin layer.

Although the ethylene-vinyl alcohol copolymer layer may be located on the surface, it is preferably located on the intermediate layer and covered with another resin. Further, even when the surface on the side not contacting the fabric is not the printing layer, it is not necessary to provide the ethylene-vinyl alcohol copolymer layer between the surface and the printing layer closest to the surface.

When the polyurethane resin layer is further laminated, the laminating position is not particularly limited and may be laminated at any position.

As the film constitution satisfying the above conditions,
When the ethylene-vinyl alcohol copolymer is abbreviated as EVOH and the polyurethane resin is abbreviated as TPU and the description is made from the surface of the side in contact with the fabric, the following film constitution can be exemplified. That is, EVOH / print, EVOH / TPU
/ Printing, TPU / EVOH / Printing, TPU / EVOH /
Examples of the film structure include TPU / printing, TPU / EVOH / printing / TPU / printing, and the like. Further, another resin layer may be appropriately laminated on these film structures.

The thickness of the ethylene-vinyl alcohol copolymer layer between the surface in contact with the fabric and the printing layer closest to the surface is not particularly limited, but may be 2 to 2
The range of 0 μm is preferable. When using an ethylene-vinyl alcohol copolymer having a high ethylene content, it is preferable to increase the thickness of the layer, and when using an ethylene-vinyl alcohol copolymer having a low ethylene content, the thickness of the layer is increased. Can be thinned.

However, if the total thickness of the ethylene-vinyl alcohol copolymer layer exceeds 30 μm, the flexibility becomes poor,
It is not preferable because the texture of the fabric is deteriorated.

The thickness of the polyurethane resin layer is
The total thickness of the layers is preferably in the range of 20 to 400 μm from the viewpoint of flexibility and texture of the fabric.

The method for producing the fabric coating film of the present invention is not particularly limited, but when the printing layer is applied only to one of the two surfaces, the film constitution of the present invention is used. It can be produced by subjecting the film formed in step (1) to printing, or can be obtained by laminating a film subjected to printing and a film not subjected to printing. However, when the printing layer is also applied to the intermediate layer, after the film is subjected to the printing process, another layer is further formed on the printing layer by the extrusion laminating method or the dry laminating method. It is manufactured by laminating. In the case of the dry laminating method, the printed surface can be further positioned on the outer surface by laminating printed films.

Further, recently, it is also possible to partially fuse and laminate by a high frequency sealing method.

The method for applying the film for covering a fabric of the present invention to a fabric is not particularly limited, and a conventional general pasting method, for example, a hot-pressure pasting method or an adhesive pasting method is used. Etc.

The surface to be attached to the fabric is not a printing surface, but a surface having at least one ethylene-vinyl alcohol copolymer layer between the printing layer and the applying surface. It is necessary to be.

The film for covering a cloth of the present invention is preferably applied to a cloth for a raincoat, a windbreaker, gloves, work clothes for handling water and the like. Also, recently, emblems with colorful designs have been attached to sportswear and children's clothing.
The emblem of the present invention is useful as an emblem directly attached to clothing such as sportswear and children's clothing.

[0027]

It is not clear why the printed pattern of the fabric coating film of the present invention attached to the colored fabric does not discolor even when the time passes or is heated, but the following may be considered. .

That is, since the ethylene-vinyl alcohol copolymer layer prevents migration of the dye contained in the fabric, the dye of the fabric does not migrate to the print layer of the fabric coating film of the present invention. , It seems that the printed pattern does not discolor.

[0029]

EXAMPLES Hereinafter, the contents of the present invention will be described more specifically by showing Examples and Comparative Examples. Of course, the present invention is not limited only by the matters described in the examples.

The discoloration of the printed pattern was examined by the following method. That is, a cloth clothing film having a print pattern is attached to a colored cloth, the surface pressure is 5 kg / cm ² , and the temperature is 120.
After heating and pressing under conditions of 12 ° C. and 12 hours for facilitating the transfer of the dye contained in the colored fabric to the film, the discolored state of the printed pattern of the fabric-clothing film was visually examined.

(Example 1) Two extruders and a circular die with two layers and three layers were used, and both outer layers were made of polyurethane resin (adipate ester polyurethane) and the core layer was made of ethylene.
A laminated film of vinyl alcohol copolymer (ethylene content 32%) was formed by an inflation coextrusion method. The entire surface of one side of the obtained laminated film was printed with a pattern to obtain a fabric covering film. The thickness of each layer was 75 μm for both polyurethane resin layers and 10 μm for the ethylene-vinyl alcohol copolymer.

The obtained fabric coating film was attached to a fabric in which polyester fibers were dyed black. In addition, the surface of the cloth clothing film to be attached to the cloth was a surface which was not subjected to printing, and a urethane adhesive was used as a method of sticking.

Then, the state of discoloration of the print pattern of the cloth-covering film attached to the cloth was examined by the hot pressing method. As a result, the printed pattern was good without any discoloration.

Comparative Example 1 A single-layer polyurethane resin (adipate ester polyurethane) film having a thickness of 150 μm was formed by the inflation method, and one surface of the film was subjected to printing to obtain a film for covering fabric.

The resulting fabric coating film was used in Example 1
The same fabric used in Example 1 was applied in the same manner as in Example 1.

Then, the state of discoloration of the print pattern of the fabric covering film attached to the fabric was examined by the above-mentioned hot pressing method. As a result, the dye on the fabric was transferred to the print layer, and the print pattern was changed to black.

[0037]

[Effect] The fabric on which the film for coating a fabric of the present invention is attached does not change the color of the printed pattern even after a long period of time and after being heated by a hot air dryer after washing. The pattern can be maintained.
Further, the emblem of the present invention directly attached to clothing such as sportswear and children's clothes does not discolor the printed pattern even when heated by a dryer after washing, and the pattern is clear forever.
