Abstract

PROBLEM TO BE SOLVED: To provide a label for identification marks of clothing in particular which is made easy in production by decreasing the required number of materials and extremely simplifying a layer structure, obviates the peeling and cracking of labels in spite of washing and cleaning as a result of the relatively small thickness for sticking, offers the good feel of use and enables a user to freely print and write characters and identification marks when needed. SOLUTION: This hot meltable label consists of a heat meltable resin layer 4 which is directly weldable to the surface of a textile fabric and an ink layer 2 which is printed on this resin layer 4 to a uniform thickness by ink thermally and mechanically stable at 160 to 230 deg.C, more particularly UV curing ink, and of which the outside surface is flattened in a manner as to be printed with another ink different in colors from this ink in order to make it possible to print the outside surface with the characters, identification marks and/or other patterns. The stock 10 formed by integrating the heat meltable resin layer 4 and the ink layer 2 is cuttable out to a label form.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is capable of printing or printing characters / identification marks on an outer surface, and is particularly suitable for wearing on clothes and the like, and is suitable for categorizing and storing the owner, the delivery destination, etc. Regarding sex labels.

[0002]

2. Description of the Related Art For example, in a laundry shop, a piece of paper on which identification characters are normally attached is attached to an item such as a stapler in order to identify a person who owns the item such as clothing that has been deposited and a delivery destination. In this procedure, even when the same item is stored for cleaning or the like, a piece of identification paper is attached each time. The work itself is simple and relatively inexpensive. However, if a large amount of such an item needs to be processed, the labor will be great.

On the other hand, as shown in FIG. 1, when a large amount of clothes are to be cleaned or sold, a label 24 having an identification mark, for example, a bar code attached to a part of the clothes is attached to the cloth 20 of the clothes. If attached, it is extremely convenient for management, especially for management of owners, delivery destinations, and the like. Such clothes include uniforms such as work clothes and office clothes of a company, costumes for rent, rental costumes for sports shops and the like.

Further, as a product to be treated in a large amount, a linen product used in a hotel or a general household, for example, a sheet of a futon as schematically shown in FIG. 2 or a cloth 22 such as a pillow cover. If the label 24 with an identification mark is attached, it is extremely effective for management such as delivery and classification. When such clothes and linen products are washed with water or subjected to normal cleaning, the label may be damaged or soiled and the identification mark may not be detected.
In order to prevent such inconvenience, JP-A-3-2728
Japanese Patent Publication No. 86 proposes a method for producing a label suitable for being attached to a cloth, a non-woven fabric or the like. In this method, the treatment process has three stages. That is, in the first step, in order to prepare a heat-sensitive transfer sheet, a heat-fusible release layer containing wax as a main component on one side of a polyester or polyamide base film and a heat-welding colored layer formed by adding a pigment to an epoxy resin. Are sequentially superposed, and at the same time, a heat resistant slip treatment layer made of silicone is applied to the opposite surface of the base film.

In the second step, the heat-welding colored layer of the heat-sensitive transfer sheet is transferred as a character / identification mark onto the image receiving body by a thermal head or the like. At that time, the transferred image receiving body is composed of a transparent heat-resistant resin polyester and a transparent copolymer polyester resin image receiving base. In the third stage, the characters / images on the image-receiving underlayer of the transferred image receiver
The identification mark is covered with a heat-welding film such as a polyester film or polyamide, and the member (cloth) to be transferred is heated and pressed to be bonded.

In this manufacturing method, since the label having the character / identification mark portion on the cloth is covered with the heat resistant film and the image receiving base layer for protection, the mark is not soiled or missing. However, as explained above, due to the multi-layer structure (7 layers), the manufacturing is complicated and it is necessary to use a large-sized printing apparatus. In addition, since the characters / identification marks are covered with the heat-resistant film and the image-receiving base layer, only the marks prepared in advance can be created. This means that it is not possible for the user to freely decide and write a desired mark each time according to the usage situation. Also, if one of the cut out individual labels is damaged for some reason, it will take a great deal of time and cost to recreate it. In addition, since the label itself is considerably thick, it feels stiff when attached to the fabric and is not comfortable to use.

In order to eliminate the difficulties caused by the above-mentioned multilayer structure, Japanese Patent Laid-Open No. 7-56511 proposes a cloth tag in which a user can freely write characters and identification marks with a thermal transfer printer or the like. This tag uses a method in which a fabric-based label is heat-welded to the underlying clothing. Then, a material obtained by sticking a heat-welding film and a layer of another adhesive to a base material composed of nylon taffeta (woven fabric layer) and an adhesive layer was used as a tag.

On the surface of the fabric layer used for the uppermost layer of this tag, characters / identification marks are printed (this is generally done by using a thermal transfer printer), so that it is necessary to make the layer thickness relatively thick. is there. Therefore, when actually used, this tag part becomes stiff due to its thickness and the adhesive layer for heat welding equivalent to it, so it is used in underwear, cutter shirts or sheets that come in contact with the body. You may experience dissatisfaction. In addition, this tag still has a large number of layers to be laminated, requires a large number of manufacturing steps and various materials, and is expensive to manufacture and sell.

SUMMARY OF THE INVENTION The object of the present invention is to solve the problems found in the prior art described above, to reduce the number of required materials, to significantly simplify the layer structure, and to facilitate manufacturing, and at the same time to attach the same. Since the thickness is relatively thin, there is no peeling or cracking on the label even after washing and cleaning, it is comfortable to use, and the user can freely print letters and identification marks when needed, especially for clothing. To provide a label for an identification mark.

[0010]

According to the present invention, the above-mentioned problem is solved by the present invention. A heat-meltable resin layer 4 which can be melted at 90 ° C. to 120 ° C. and directly welded to the surface of a woven fabric and 160 ° C. on the resin layer 4.
Printed to a uniform thickness with ink that is thermally and mechanically stable even at ~ 230 ° C, especially UV curable ink,
An ink layer 2 is formed so that the outer surface can be printed with characters / identification marks and / or other patterns, so that another ink having a different color from the ink can be printed on the surface, This is solved by a heat-fusible label capable of cutting out the material 10 in which the heat-fusible resin layer 4 and the ink layer 2 are integrated into a label.

Further advantageous configurations according to the invention are described in the dependent claims.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the structure and advantages of the present invention will be described in more detail with reference to the accompanying drawings on the basis of preferred embodiments. FIG. 3 is a sectional view showing the basic structure of the label material 10 according to the present invention. In this label material 10, the ultraviolet curable ink layer 2 is applied on the heat-meltable resin layer 4 serving as the basic layer by a printing technique (for example, a screen printing method) (FIG. 3A). Release paper 6 if necessary
Is brought into close contact with the heat-meltable resin layer 4 of the label material 10 by heat temporary fixing (FIG. 3B). The release paper 6 is impregnated with silicone, wax, etc., as is commonly used. The closely adhered label material 10 can be easily separated from the release paper 6.

Forming the label product 15 composed of the label material 10 and the release paper 6 into a uniform long tape is advantageous for continuous production. Using the heat-meltable resin layer 4 as a base, an ultraviolet curable ink is printed thereon in a layered manner by screen printing or the like to a uniform thickness. This ink is usually used in a relatively bright color, for example, white. When a character / identification mark is printed using a label printer, black or dark gray ink that is different from the contrast of the white ink of the base is used. Of course, the reverse, that is, it is also possible to make the base with black ink and print the identification mark with white ink.

It is also possible to use the label product 15 thus prepared as a single sheet separated into one label by die cutting. Also, as shown in FIG.
It is also possible to manufacture the roll 18 in a state where the label material is formed into individual labels while being in close contact with the release paper 6. If it is supplied as a roll wound in this way, the character / identification mark can be printed or printed at any time by a bar code printer or the like when needed by the user, and the printing operation becomes very easy.

FIG. 4 shows the roll in a state in which printing has been completed. For the sake of simplicity, only one label is printed with a bar code. Etc. can also be printed. A significant advantage of the label product according to the present invention is that characters / identification marks and / or other patterns can be printed or printed on the label at any time even immediately before being applied to a fabric.

Although not shown, a label product in which sheets of the same size are sequentially folded, and stacked and stored can be manufactured instead of the label wound in a roll shape. Further, sprocket holes may be provided at both ends or one end of the label product 15 in order to ensure the feeding of the roll sheet or the folded sheet.

Before or after the identification mark or the like is printed by a printer or the like, in order to add a pattern or identification information for another purpose, if necessary, a color other than white or black, for example, is added. It is also possible to apply an ultraviolet curable ink such as red or blue. The heat-melting resin used can be heat-welded to the substrate (fabric) in the range of 90 ℃ to 120 ℃, it does not change with time even at room temperature, and it is desirable to use a material with excellent abrasion resistance. A resin made from polyester is possible. The resin used has an optimum thickness depending on the thickness of the base and the twisted yarn of the base fiber.

Further, the UV-curable ink uses a substance which is stable even when heated at the time of adhesion (about 120 to 150 ° C.). As shown in FIG. 5, the thickness of each of the heat-fusible resin layer 4 and the heat-resistant ink layer 2 is 1/3 to 10 of the diameter of the twisted yarn 26 of the fabric 20.
It is good that it is one-third. For regular clothing and linen products,
The preferable thickness of the label material 10 is about 130 μm, the thickness of the heat-welding resin layer is 90 to 110 μm, and the thickness of the ultraviolet curable ink layer is 10 to 30 μm. Of course, extra thick fabrics require the use of materials thicker than the above values.

For heat welding, first, as shown in FIG. 5A, the heat-welding resin layer of the label material 10 is placed on the cloth 20 (FIG. 5A), and the iron or the iron heated to about 120 ° C. to 150 ° C. is used. The label blank 10 is pressed against the cloth 20 with a heating press member (not shown). In such a state, FIG.
As shown in, the heat-welding resin layer melts and penetrates between the twisted yarns of the fabric 20. In this case, since the heat-resistant ink ribbon is used for printing, the barcode is also stable in the heated state, and the resin 4'in the molten state does not penetrate into the ultraviolet curable ink layer 2. Here, when the iron is removed, the molten heat-fusible resin layer is solidified.

In the above description, the case where the label of the present invention is applied to a woven fabric has been described. However, the label of the present invention can be applied not only to the woven fabric but also to wood, metal, resin plate and the like.

[0021]

As described above, when the heat-fusible label according to the present invention is used, the number of required materials (layers) can be reduced, the layer structure can be simplified, and the production can be extremely facilitated. Since the thickness is relatively thin, the label is not peeled or cracked even after cleaning, and it is comfortable to use. Since the user can freely print and write the characters / identification marks when necessary, the degree of freedom in use is great. Further, according to the present invention, it should be noted that the label attached to the cloth looks as if it was directly heat-transfer printed on the cloth, and the finished state is very elegant.
