を損なうという課題もある。(Problems to be Solved by the Invention) Conventionally, after a blanket base fabric is sewn, a flexible heating wire is wired between joints, so that the wiring process could not be automated, and many man-hours were spent. In addition, the main body bonding with the hot melt adhesive also has a problem in that the raising of the blanket base fabric is collapsed by the hot press, and the texture is impaired.

There are aqueous emulsion adhesives, (B) polar solvent-based adhesives and (C) conductive particle-containing adhesives. The adhesives of (A) and (B) are based on the fact that the dielectric constant and the dielectric loss factor of water and the polar solvent are very large. On the other hand, in the adhesive containing dielectric particles (C), the charge carriers in the dielectric particles behave in response to a high-frequency electric field, causing dielectric loss. As a result, it exhibits dielectric properties like a Maxwell-Wagner composite dielectric, exhibits a large dielectric constant and a large dielectric loss factor, and generates large heat due to the dielectric loss under a high-frequency electric field.

している。As the aqueous emulsion adhesive used in the present invention, an acrylic resin, an ethylene-vinyl acetate copolymer, polyvinyl acetate, vinyl urethane, a maleic anhydride resin, and an adhesive mainly containing these copolymers are used. Each of them contains a large amount of water, and is very well heated by dielectric heating, the water evaporates, and can be dried and adhered in a short time. This adhesive forms an adhesive pattern on the lower blanket base fabric and adheres to the upper base fabric by a dielectric heating method.
The wiring of the flexible heating wire may be before or after this bonding. The polar solvent-based adhesive used in the present invention is an adhesive dissolved by a polar welding agent, particularly a proton solvent, has a large dielectric loss factor, and generates heat well under a high-frequency electric field. Specific materials include varnishes such as polyurethane, polyamide, polyester, vinyl acetate copolymer, and rubber, as well as general polar solvent adhesives. However, in terms of the factory environment, the aqueous emulsion has a lower solvent content and is practical. The conductive particle-containing adhesive used in the present invention refers to one in which conductive particles or conductive whiskers are dispersed in an adhesive, but is dispersed in a hot melt adhesive and has a volume resistivity of 10 2 to 10 8 Ω.・ The one in cm is optimal. If this volume resistivity is too low, the heat will ignite too much,
If it is too high, the heat generation efficiency is so low that bonding cannot be performed. As conductive particles or conductive whiskers, carbon black, copper,
Suitable materials include aluminum, tin oxide and zinc oxide, and among them, carbon black and aluminum are most suitable.

効である。The dielectric heating method in the present invention, under a high-frequency electric field,
The adhesive having a high dielectric loss factor is heated and bonded, and can be similarly heated and bonded by applying microwaves. A high-frequency electric field in the range of 2 MHz to several tens of MHz is used. Above all, those having a range of 6 to 80 MHz are used. Among them, about 6 to 8 MHz is practical. When applying this dielectric heating method, it is efficient that only the adhesive is heated best and other substrates are not heated much directly. That is, it is important that the dielectric loss factor of the adhesive is orders of magnitude higher than other substrates. The above (A),
The adhesives of (B) and (C) satisfy this condition.
Even when the adhesive base material has flexible linear heat generation, if the heat generation wire is continuous without any breakage, heat generation in a high-frequency electric field and local heat generation effects do not occur. In addition, even if the wire is a flexible polyvinyl chloride jacket having a relatively large dielectric constant (ε = 5 to 10), the adhesive of the present invention has an order of magnitude higher dielectric loss factor. The method is very effective.

After the upper blanket base cloth 11 was put thereon, it was sandwiched between the dielectric heating electrode plates 8, heated by the high-frequency electric field 7, and adhered. The adhesive for dielectric heating used here was an acrylic resin-based aqueous emulsion adhesive.
