Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat-bonding tape for bonding fabrics, films and the like constituting a fiber product by heat-sealing, and a fiber product bonded using a heat-bonding tape.

[0002]

2. Description of the Related Art A conventional heat-adhesive tape comprises only a heat-sealing layer as represented by a hemming tape.
As disclosed in Japanese Patent No. 252372, it is inserted between the doughs, and after the insertion, the doughs are joined by heating and pressing.

[0003] However, when inserted between cloths, the thermal adhesive tape and the cloth are apt to be displaced, and when heated and press-bonded with the dislocation, distortion and wrinkles are generated at the joints. There is a problem that the value as a product is significantly reduced or the value of the product is lost.
Further, when the heated and press-bonded material is to be peeled off once, it has a drawback that the fabric cannot be repaired because the fabric is damaged or the like.

Therefore, when manufacturing a product using a thermal adhesive tape, it is necessary to pay attention so that the thermal adhesive tape and the cloth do not shift, and it takes much time to insert the cloth and the thermal adhesive tape. And workability remains,
Improvement was required.

[0005]

The thermal adhesive tape according to the present invention prevents the thermal adhesive tape and the cloth from being displaced when the thermal adhesive tape is inserted, and can be used in a sewing process while maintaining the same thermal adhesive effect as before. It is an object of the present invention to provide a thermal adhesive tape having improved workability during thermal adhesive work.

[0006]

Means for Solving the Problems The inventors of the present invention have made intensive studies to solve the above-mentioned problems, and as a result, have improved the workability while maintaining the same adhesiveness as that of a conventional thermal adhesive tape. It has reached thermal adhesive tape.

That is, the present invention is a thermal adhesive tape having a thermal adhesive layer, wherein the adhesive material is partially disposed on at least one surface of the thermal adhesive layer.

[0008] The present invention also provides a textile product in which at least a part of a joining portion constituting the textile product has the thermal adhesive tape inserted between the fabrics and is fusion-bonded with the thermal adhesive tape. is there.

Further, the present invention is a method for producing a fiber product in which the above-mentioned heat adhesive tape is disposed between cloths, fixed with an adhesive material of the heat adhesive tape, and then fused by heat. .

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The heat-adhesive tape of the present invention can be suitably used for textiles as described later, and synthetic fibers such as polyester and polyamide, cotton and wool are used for the textiles. Woven or knitted or non-woven fabrics using natural fibers alone or two or more of them, waterproof fabrics obtained by coating or bonding a urethane resin or a waterproof film on a woven or knitted fabric, and further films made of polyester or polyamide resin And attachments such as fasteners.

Therefore, the material for the heat-sealing layer of the heat-adhesive tape of the present invention may be selected with emphasis on the adhesiveness to the above-mentioned material constituting the textile product. From the viewpoints of workability, cost, and the like, it is preferable to use urethane-based, polyester-based, or polyamide-based resins. As such an embodiment, a resin made of such a resin is also preferable.

It is important for the heat-adhesive tape of the present invention that an adhesive material is disposed on at least one surface of the heat-sealing layer. By arranging the material having tackiness at room temperature on the heat-sealing layer, even when inserting the heat-adhesive tape between the cloth to be bonded and the cloth, the temporary fixing until the heat fusion can be surely performed, It is possible to prevent the tape from slipping and to improve the workability during the thermal bonding operation.

The adhesive material in the present invention only needs to have an adhesive property at room temperature, and may be an acrylic or urethane resin.
Although not particularly limited, such as a silicone-based or urethane-based synthetic rubber, it is preferable to use an acrylic copolymer-based resin from the viewpoint of adhesiveness and workability.

The adhesive material in the heat-adhesive tape of the present invention is partially applied onto the heat-sealing layer in order to sufficiently bring out the adhesion performance of the heat-sealing layer and secure the bonding strength at the joint. It is to arrange. By partially arranging on the heat-sealing layer, for example, when inserting between doughs and performing heating for fusion and fusing the heat-sealing layer to join the fabric surface, heat-sealing Since there is a portion where the layer and the fabric surface are in direct contact, it is possible to obtain a sufficient adhesive strength. When applied and arranged on the entire surface of the heat-sealing layer, the adhesive material becomes an obstacle and the heat-sealing layer cannot penetrate sufficiently to the fabric surface, resulting in insufficient adhesion strength. This is not preferable because puncturing occurs.

As the mode of partially disposing the adhesive material on the heat-sealing layer, for example, a dot shape as shown in FIG. 4, a stripe shape as shown in FIG. 5, a lattice shape as shown in FIG. However, it is important that the heat-sealing layer is in direct contact with the fabric surface to which the heat-sealing layer is directly adhered, and the present invention is not particularly limited thereto.

The amount of the adhesive material to be disposed on the heat-sealing layer is, for example, when a heat-bonding tape is placed at a predetermined position when the heat-bonding is performed by inserting the material between the cloths.
It is only necessary to ensure temporary adhesiveness so that the thermal adhesive tape does not deviate from a predetermined position at the time of work such as folding back, and it is more preferable to reduce the amount of use and arrangement area as much as possible if temporary adhesiveness can be ensured.

As a method of disposing the tacky material in the heat bonding layer according to the present invention, there is a method of directly coating the heat bonding layer coated on the release paper. As a coating method, gravure coating is excellent in terms of uniformity, but is not particularly limited as long as it can be coated in a dot shape, a stripe shape, or a grid shape.

As another method of disposing the adhesive material in the heat-sealing layer according to the present invention, an adhesive layer formed by coating or the like on a release paper is bonded to the heat-sealing layer, and then the release paper is peeled off. There are also ways to do that. In these cases, it is possible to obtain a thermal adhesive tape in which release paper is further provided on the thermal adhesive layer or an adhesive material, and workability by preventing adhesion in unnecessary places such as adhesion between thermal adhesive tapes. This is preferable because it is possible to improve

The adhesive material according to the present invention may be a material which is partially applied and arranged on one side of the heat-sealing layer as shown in FIG. 1 or a material which is coated on both sides of the heat-sealing layer as shown in FIG. Is partially applied and disposed on

Further, as shown in FIG. 3, a material to which a release paper is attached is also preferable in that the adhesion of the thermal adhesive tapes is prevented.

The thermal adhesive tape of the present invention can be used for clothing for fashion, uniforms, sports, Japanese clothes, etc., built-up bedclothes such as curtains, futon covers, pillow cases, and daily necessities such as shawls, bags and shoes. It can be used. Particularly preferably, in the case of a sewing machine using a sewing thread, there is a problem of water leakage due to a gap or a hole in a joint portion, but there is no gap or a needle hole in joining with an adhesive tape, and water from the joint portion has no problem. Since water leakage is prevented, it is particularly effective to use it for joining rain clothes, cold clothes, bags, shoes, and the like that require waterproof performance.

EXAMPLES Hereinafter, the thermal adhesive tape of the present invention will be described with reference to examples and comparative examples, but the present invention is not limited to these examples.

(Measurement / Evaluation) (1) Peel Strength of Thermal Adhesive Tape A thermal adhesive tape is sandwiched between cloths, and subjected to thermocompression bonding using a flat plate press at a temperature of 160 ° C., a pressure of 200 g / cm ² , and a time of 20 seconds. After bonding, sample cut to 2.5cm width × about 15cm, gripping interval 5cm, pulling speed 10c
Peel strength was measured using a constant-speed elongation type tensile tester set at m / min. (2) Workability The workability in bonding the hem of the pants to the hem was evaluated on a three-point scale. ：: good workability without displacement of adhesive tape Δ: slight displacement of adhesive tape ×: poor workability of displacement of adhesive tape

Example 1 A heat-sealing resin (polyester polyurethane, flow starting point 100 ° C.) was heated to a temperature equal to or higher than the flow starting point in advance, and a fluidized polyurethane heat-sealing solution was applied using a knife over roll coater. Release paper EV130T
Coated on PD (manufactured by Lintec Co., Ltd.), thickness 110 μm
Was obtained.

Next, an acrylic copolymer plaster EH (manufactured by Shin-Nakamura Chemical Co., Ltd.) is applied as a sticky resin on the film of the heat-sealing layer in a dot form as shown in FIG. 4 by a gravure coater. Then, the resultant was dried at 80 ° C. with hot air to obtain a heat adhesive tape of the present invention in which an adhesive material was partially disposed.

Next, 146 warp yarns composed of a nylon 6 filament yarn of 52 filaments and 78 decitex are used.
Waterproof pants were sewn using a three-layer waterproof fabric in which a woven fabric of 94 inches / inch yarn / inch was coated with urethane, and a tricot knitted fabric consisting of 22 filaments of 22 filaments and 7 filaments of nylon 66 filaments was adhered to the coated surface. .

Next, using this thermal adhesive tape, the hem of the pants was raised to evaluate the workability and the adhesive strength of the portion. The displacement of the thermal adhesive tape when the thermal adhesive tape of the present example was sandwiched between the fabrics was prevented, and the work was easy. Table 1 shows the evaluation results.

(Example 2) The thermal adhesive tape and the pants of the present invention were sewn in the same manner as in Example 1 except that the adhesive resin was applied in a grid pattern as shown in FIG. evaluated. The displacement of the thermal adhesive tape when the thermal adhesive tape of this example was sandwiched between the fabrics was prevented, and the work was easy. Table 1 shows the evaluation results.

(Comparative Example 1) A heat-sealing resin (polyester-based polyurethane, flow starting point 100 ° C.) was heated to a temperature equal to or higher than the flow starting point in advance, and the fluidized polyurethane heat-sealing solution was applied using a knife over roll coater. Release paper EV130T
Coated on PD (manufactured by Lintec Co., Ltd.), thickness 110 μm
Was obtained as a heat-bonded tape.

Pants similar to those in Example 1 were sewn using this heat-adhesive tape, and workability and adhesive strength were evaluated. When sandwiched between the fabrics, the thermal adhesive tape slipped, and the tape could not be easily sandwiched at a desired position, resulting in poor workability. Table 1 shows the evaluation results.

(Comparative Example 2) A heat-sealing resin (polyester-based polyurethane, flow starting point 100 ° C.) was heated to a temperature equal to or higher than the flow starting point in advance, and the fluidized polyurethane heat-sealing solution was applied using a knife over roll coater. Release paper EV130T
Coated on PD (manufactured by Lintec Co., Ltd.), thickness 110 μm
Was obtained.

Next, an acrylic copolymer plaster EH (manufactured by Shin-Nakamura Chemical Co., Ltd.) is applied to the entire heat-sealed film as a sticky resin with a knife over roll coater, and then heated at 80 ° C. with hot air. A dried and tacky material was provided on the entire surface to obtain a heat adhesive tape.

Using this adhesive tape, the same pants as in Example 1 were sewn to evaluate workability and adhesive strength. The heat adhesive tape was prevented from slipping when sandwiched between the fabrics, and was easy to work. However, sufficient adhesive strength was not obtained. Table 1 shows the evaluation results.

[0034]

[Table 1]

[0035]

According to the thermal adhesive tape of the present invention, since the adhesive material is partially disposed on the thermal adhesive layer, it is put on the fabric at the time of thermal adhesive work while maintaining the adhesive strength. This prevents the tape from slipping at the time, thereby improving the workability during the thermal bonding operation.

In addition, unlike the sewing stitch using a sewing thread, the joining with the adhesive tape prevents water leakage from the joining portion because there is no gap or a needle hole, so that raincoats that require waterproof performance are required. It is particularly effective to use it for bonding of clothing, winter clothing, bags, shoes, and the like.
