Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape-shaped cloth provided with a hot melt adhesive. More specifically, the present invention relates to a cloth tape which is printed with an image of characters and symbols by a thermal transfer printer and then hot-melt bonded to clothing or the like.

[0002]

2. Description of the Related Art It is significant to use a label for managing cloth products such as clothes, but in consideration of the familiarity and the durability against washing, it is necessary to firmly bond the cloth label to the cloth product. Is most preferred.

Labels used for management generally have different information to be recorded for each label. Therefore, it is an effective means to use a combination of a computer and a printer, a word processor or a label word processor.

In view of the above objects and means, the present inventors have hitherto carried out thermal transfer printing on a cloth lined with a hot melt adhesive film using a thermal transfer ribbon containing a dye, and then, on clothing or the like. The inventors invented a method of performing dry dyeing at the same time as hot-melt adhesion by placing and dry heating. The hot-melt adhesive film-backed fabric used for this was actually taped. As a manufacturing method thereof, a hot melt adhesive film and a cloth were laminated and then cut into a tape shape by fusion cutting.

[0005]

However, when the fusing cut is performed, the fusing part melts and becomes thicker than the central part of the tape, and when the tape is wound, it meanders or swells only at the ends. There was a problem from an aesthetic point of view. Not only that, but in the printing part of the thermal transfer printer, the raised part between the thermal head and the platen roller acts as a sticking stick, and the adhesiveness between the thermal transfer ribbon and the cloth surface deteriorates at the center of the tape and printing is performed. There was a problem that the quality was poor or that many of them could not be filled when they were filled in the cassette of the label word processor.

The present invention solves these problems, improves the meandering at the time of winding, improves the adhesion between the thermal transfer ribbon and the cloth surface in the printing section of the thermal transfer printer, and improves the printing quality. An object of the present invention is to provide an adhesive-attached cloth tape having a large cassette filling amount and a method for manufacturing the same.

[0007]

The present invention adopts the following means in order to solve the above problems. That is, the cloth tape with an adhesive of the present invention is a cloth tape with an adhesive obtained by laminating a hot melt adhesive film and a cloth, and the structure of the cloth is substantially formed on both sides in the longitudinal direction of the tape. It is characterized by being held. Further, the method for producing a fabric tape with an adhesive of the present invention is a roll in which a hot melt adhesive film and a fabric are laminated and then wound around a core, and the roll is a blade having a temperature lower than the melting point of the hot melt adhesive film. It is characterized in that it is cut into a roll of cloth tape with an adhesive of a predetermined width by cutting with a cut-out method using a sheet-like material, or alternatively, following these operations, while unraveling the tape at high speed, It is characterized by passing through. Alternatively, a hot-melt adhesive film and a cloth are laminated to form a sheet, which is wound around a core to form a roll, and the sheet is pushed out from the roll by using a blade-shaped material arranged at a predetermined width It is characterized in that it is cut into a tape shape with, and each tape is wound up, or alternatively, following those operations,
While pulling out the sheet from the roll, it is cut into a tape shape by a push-cut method using blades arranged at intervals of a predetermined width, and each tape is wound into a roll of a cloth tape with an adhesive having a predetermined width, Then, the tape is characterized by being passed through the flame while being unwound at high speed, or alternatively, after being cut into tapes, each tape is wound while passing through the flame. is there.

The cloth referred to in the present invention includes natural fibers such as silk and cotton, synthetic fibers such as polyester type, polyamide type and polyacrylonitrile type, regenerated fibers of cellulose type and protein type and semi-synthetic fibers. It refers to a woven fabric, a knitted fabric, a non-woven fabric, and the like, and those more preferably used among them will be clarified later. Also,
The fabric structure referred to in the present invention refers to its woven structure in the case of a woven fabric and its knitted structure in the case of a knitted fabric.
In either case of knitted fabric or non-woven fabric, a fabric structure including a fabric weight and a thickness is collectively referred to as a fabric structure.

[0009]

The present invention will be described in more detail below.

Since the cloth tape with a hot melt adhesive of the present invention has been conventionally cut by a fusing cutter, the thickness of the tape on both sides in the longitudinal direction becomes thicker than the thickness near the center of the tape, and the tape is wound up. A specific cutting method is adopted to improve the defects such as meandering at times and print quality of the thermal transfer printer due to poor adhesion between the thermal transfer ribbon and the cloth surface at the center of the tape in the thermal transfer printer. By doing so, it has succeeded in making the thickness of the tape on both sides in the longitudinal direction of the tape substantially equal to the thickness near the center of the tape. By such a method, in the print portion of the thermal transfer printer, the thermal transfer ribbon and the cloth tape sandwiched between the thermal head and the platen roller have good adhesion, and defects such as blurring of a printed image are improved.

The thickness of the fabric tape with a hot melt adhesive of the present invention is preferably 50 to 200 μm, because if it is not supple, a discomfort is felt when it is adhered to clothing or the like. More preferably, it is 80 to 150 μm. Generally, the thinner the sheet, the more supple it is, but if it is too thin, it is transparent, and the quality as a label is impaired. Note that the tape may be cut after printing to form a label.

The suppleness and the anti-transparency are generally contradictory as described above, but in order to satisfy them at the same time, it is preferable that the fabric is mainly made of ultrafine fibers having a single fiber fineness of 0.0001 to 1 denier. Single fiber fineness is 0.0001-
0.5 denier is more preferable, and 0.0001-
More preferably 0.1 denier. Since the cloth made of such ultrafine fibers reflects light irregularly, even if it is thin, the transparency is exhibited.

The ultrafine fibers are preferably used because they contribute not only to the flexibility and the transparency preventing property as described above but also to the improvement of the printing quality of the thermal transfer printer. Furthermore, if the fibers are entangled with each other, it is possible to provide still more preferable print quality and transparency.

In order to obtain even better printing quality, the surface roughness of the cloth surface opposite to the surface on which the hot melt adhesive film is laminated, that is, the printing surface, is the center line average roughness in the longitudinal direction of the tape. 2 to 8 μm, maximum height 20 to 80
It is preferable that the center line average roughness is 1 to 6 μm and the maximum height is 10 to 60 μm in the width direction of the tape. They are 3 to 7 μm, 30 to 70 μm,
It is more preferably 2 to 5 μm and 20 to 50 μm.

The composition of the fiber is not particularly limited, but in the case of the fiber made of polyester such as polyethylene terephthalate, it is subjected to thermal transfer printing using a thermal transfer ribbon containing a sublimation dye, and dry heating to sublimate transfer. It is preferably used in a method of dyeing.

The composition of the hot melt adhesive film used for these is not limited, but a preferable example thereof is a polyester type or a polyamide type. Among them, the polyester type is preferably used because it has a low swelling property with respect to water and thus has excellent wash resistance. The thickness is not particularly limited, but if it is too thick, it becomes stiff, and if it is too thin, the adhesive ability deteriorates. From this point of view, those having a thickness of about 30 to 70 μm are preferably used. The melting point is also not particularly limited, but considering that it is washed with hot water, it is approximately 90 to 150 ° C.
Is preferred.

Next, a method for producing the cloth tape with a hot melt adhesive as described above will be described below.

In order to produce the above-mentioned cloth tape, the hot-melt adhesive film and the cloth are laminated and then wound around a core to form a roll, and the roll has a blade shape at a temperature lower than the melting point of the hot-melt adhesive film. It is cut by a push-cut method using a thing. The method of cutting by such a push-cutting method can be achieved by a method of sliding a blade on an object to be cut such as a guillotine cutter or a disk-type rotary cutter to cut. The width to be cut may be appropriately determined according to the purpose. Here, when the temperature of the blade is equal to or higher than the melting point of the hot-melt adhesive film, the hot-melt adhesive film melts at the cut surface at the time of cutting and causes the tapes to be laminated to adhere to each other. Be careful about the temperature.

When cut by the above-mentioned method, in some cases, the fibers of the cloth are pulled out to the cut surface, and a beard appears to be formed from the end of the tape. In such a case, when the tape is pulled out and passed through the flame at high speed, only the beard can be shrunk and the beard can be substantially removed. Therefore, it is preferable to appropriately use this method.

As another method, a hot melt adhesive film and a cloth are laminated to form a sheet, which is wound around a core to form a roll, and the blades are arranged at predetermined intervals while the sheet is pulled out from the roll. It is also possible to cut the tape into a tape-like shape and wind each tape. In this case, the possibility of whiskers is lower than in the above method, but in the case of whiskers, the tape may be unwound at high speed as described above and passed through the flame. Alternatively, each tape may be wound while passing through a flame before winding the tape cut by the blade.

The method of laminating the hot-melt adhesive film and the cloth can be achieved by superposing the hot-melt adhesive film and the cloth and calendering them. However, the hot-melt adhesive film is excessively heated or pressed. May penetrate too much into the cloth, and the adhesiveness to the adherend such as clothing may deteriorate when it is made into a label, so it is necessary to perform appropriate calendering. Processing conditions vary depending on the type of the hot melt adhesive film, but for example, in the case of a polyester hot melt adhesive film having a melting point of 114 ° C. and a thickness of 50 μm, the temperature is 80 to 120 ° C., the pressure is ^{2 to} 8 kg / cm ² , The speed is preferably 1 to 20 m / min. More preferably, the temperature is 90 to 110 ° C. and the pressure is 3
˜6 kg / cm ² , speed 2˜10 m / min. However, in the calendar processing machine, it is not necessary to heat the roller on the side where the hot melt adhesive film hits,
The roller on the side where the cloth hits is heated so as to be in the above temperature range.

As the cloth to be used, it is preferable to use a cloth made of ultrafine fibers as described above, but it is very difficult to entangle the fibers by high-pressure water jet treatment (water jet punch treatment) before the above-mentioned lamination. preferable. This not only suppresses the occurrence of whiskers when cutting later, but also contributes to print quality.

Further, as described above, in order to improve the printing quality, it is also preferable to calender the cloth before laminating the hot melt adhesive film and the cloth.
The conditions are a temperature of 100 to 150 ° C. and a pressure of 10 to 80 k.
g / cm ² and a speed of 5 to 40 m / min are preferable, and a temperature of 110 to 140 ° C., a pressure of 20 to 60 kg / cm ² and a speed of 10 to 30 m / min are more preferable.

[0024]

The present invention will be described in more detail with reference to the following examples. It should be noted that the scope of the validity and rights of the present invention is not limited to or limited by this.

Example 1 First, a high density fabric composed of 700 warp and weft yarns of 700 ultrafine polyester filaments having a monofilament fineness of 0.06 denier was subjected to a water jet punch treatment, and then a temperature of 1 was applied.
Calendar processing was performed under the conditions of 25 ° C., pressure of 40 Kg / cm ² , and speed of 20 m / min.

Next, the above calendered cloth is superposed with a polyester hot melt adhesive film having a melting point of 114 ° C. and a thickness of 50 μm, and the temperature is 100 ° C. so that the heating roller contacts the cloth side. Pressure 4.5kg
/ Cm ² and a speed of 3 m / min were calendered and wound to obtain a roll of a laminated sheet.

This roll was sequentially cut into a predetermined width by a method of pressing down with a guillotine cutter consisting of a blade at room temperature to obtain a target roll of cloth tape with a hot melt adhesive.

This tape has the same thickness on both sides in the longitudinal direction as the central portion of the tape, and when printed on a thermal transfer printer, a sharp image quality could be obtained.

Example 2 The tape obtained above had a beard on both sides, so it was rewound while passing through a flame at high speed. As a result, a good looking tape was obtained in which the beard was removed and the thickness of both sides was the same as that of the center of the tape.

[0030]

EFFECTS OF THE INVENTION According to the present invention, a thermal transfer ribbon containing a dye is used to perform thermal transfer printing on a fabric lined with a hot melt adhesive film, and then the fabric is placed on clothes or the like to be dry-heated and hot-melt-adhered at the same time. In the method of dyeing, it is possible to provide good appearance and print quality of the tape used.
