This invention is an adhesive tape in which a pressure-sensitive adhesive is attached to a base fabric woven from flat yarns made of thermoplastic resin, and which can be used as a packaging material that can be cut by hand in the weft direction orthogonal to the longitudinal direction of the tape. The present invention relates to a method for manufacturing the adhesive tape used. Conventionally, as an example of this type of tape,
-30362 publication is known. The adhesive tape described in the publication has a base fabric woven with flat yarn made of thermoplastic resin, particularly polyalkylene, a laminate layer of the same material as the above-mentioned material is attached to one side of the base fabric, and a pressure-sensitive adhesive is attached to the other side. However, the structure of the base fabric is formed so that the tear strength in the weft direction is lower than that in the warp direction, and as an example of this reduction, a resin with a low thermal softening area and low crystallinity is mixed in the warp threads. A method in which the warp threads are deteriorated by heat treatment of the laminate. A method in which the draw ratio of warp yarns is smaller than that of weft yarns. Alternatively, the folding density of the warp yarns is made smaller than the density of the weft yarns. Alternatively, a method has been proposed in which the denier numbers of each yarn are made to vary considerably. By the way, the adhesive tape formed by the above method does have a reduced tear strength in the tape's weft direction and can be cut by hand, but at the same time, its tear strength in the warp direction also decreases, making it necessary to increase the strength. It was insufficient as a packaging material for this purpose. The object of the present invention is to form a tape with a tear strength that can be easily cut by hand without using scissors or cutters in the weft direction, and at the same time to ensure sufficient tensile strength in the warp direction. An object of the present invention is to provide a method for producing an adhesive tape that can be finished into a desired product. In the method for producing an adhesive tape according to the present invention, a flat yarn molded from a thermoplastic resin such as polypropylene or polyethylene resin is woven to obtain a base fabric for the tape.
Weaving is done by making the warp thinner and increasing the stitching density, and by making the weft thicker and reducing the stitching density.
The product is manufactured by processing the base fabric in three steps. In the first step, one side of the base fabric is activated by corona discharge treatment, and the treated side is coated with the base fabric. The laminate layer is attached by extrusion laminating using the same resin as the flat yarn. A second step is added after cooling the laminate layer. In the second step, similar to the first step, the attached laminate layer is subjected to corona discharge treatment and then extrusion lamination is performed to form a double laminate layer. The third step is to apply a pressure sensitive adhesive to one side of the base fabric opposite to the above. By the way, when the extrusion lamination process of the first step is performed, the flat yarn is deteriorated by the heat, but since the warp yarn is thin, the deterioration rate is synergistically greater than that of the weft yarn. If this continues, the tear strength of the tape in the weft direction will decrease, and the tensile strength in the warp direction will also decrease at the same time. Therefore, research has been conducted to increase the tensile strength in the warp direction by changing the structure of the base fabric in various ways. However, if the warp direction is made stronger, the weft direction is also made stronger, and it was considered difficult to solve this contradictory technique, but as a result of repeated research, the inventor found that the warp threads were thin, but the weft density was high. As mentioned above, an experiment was conducted in which the second step was performed in addition to the first step. As a result, by performing extrusion lamination processing in the second step, the laminate layer provided in the first step is softened by the heat of the molten metal, and the resin of the laminate layer is applied to the gaps between the warp and warp threads of the base fabric. It penetrates and exerts an anchoring effect, strengthening the binding force of the warp and warp threads and further strengthening the fixation of each thread. Furthermore, when extrusion lamination is performed in the second step, the heat will naturally deteriorate the yarn, but the overall thickness of the laminated layers obtained in the first and second steps will It supports the tensile strength in the direction. Therefore, the tensile strength in the warp direction of the tape was maintained at a level sufficient for practical use due to the thin warp threads but high implant density and the overall thickness of the laminate layer. However, even if the laminate layer is formed at once to the above-mentioned total thickness, the desired product cannot be obtained, so by performing the lamination process in two parts as described above, the fixation between the warp and warp threads can be achieved. This is further promoted than in the case of one time, and when the tape is manually torn in the weft direction, the warp threads do not escape in the direction of tearing due to the tearing force, and all of the tearing force is applied to the warp threads. Experiments have shown that it can be easily torn by hand. The present invention will be explained below with reference to Examples. As shown in FIG. 1, a tape-shaped base fabric 1 is formed. The warp yarns 2 and weft yarns 3 are polypropylene flat yarns, which are woven in a plain weave structure according to the values shown in the table below.

A range of ~25 pieces/inch was able to achieve the objective of the present invention. A first step, a second step, and a third step are added to the base fabric 1 having the surface structure as shown in FIG. First step: After corona discharge treatment is applied to one side of the base fabric 1, that side is coated with a molten polypropylene heated to 300 to 310°C to a thickness of about 50μ by extrusion lamination, cooled, and the second A first laminate layer 4 is deposited as shown. Second step: Corona discharge treatment is applied to the surface of the first laminate layer 4, and the second laminate layer 5 is laminated to a thickness of about 20μ as shown in Figure 3 by extrusion lamination. . Third step: Corona discharge treatment is applied to the surface of the base fabric 1 on which the warp and warp threads 2 and 3 are exposed, which is opposite to the side on which the laminate layers 4 and 5 are provided, and then a pressure-sensitive adhesive is applied as shown in FIG.

る。[Table] In the above table, the tear strength when the first laminate layer is attached is as high as 2.33 kg, and it is difficult to tear it by hand. However, by adding two laminate layers, the thickness of the layer increased, but the fixation between each yarn became higher, and the tearing force was halved to 1.58 kg, making it easy to cut by hand. Incidentally, even if you try to tear the tape in the warp direction, you cannot do it by hand, and tests have shown that the tearing force required is 3 to 4 times that in the weft direction. It has been demonstrated that it can be sufficiently improved. As described above, according to the method for manufacturing an adhesive tape according to the present invention, the warp of the base fabric woven with flat yarns of thermoplastic resin is formed with a lower denier and higher implant density than the weft, and the base fabric is It is manufactured by activating one side and applying extrusion lamination to that side twice, then activating the other side of the base fabric and attaching a pressure-sensitive adhesive.
In combination with the structure of the base fabric and double extrusion lamination, we succeeded in increasing the tensile strength of the tape in the warp direction while reducing the tear strength in the weft direction. It can be fully used as a packaging material and can be easily cut to the required length by hand. Furthermore, since the process of the present invention is simple and can be manufactured using conventional weaving machines and extrusion laminating machines,
Tapes of various widths can be provided at low cost.
