摘要:
A process for producing an adhesive type heat-generation according to the present invention comprises an adhesive layer forming process 30 and a heating composition filling and the adhesive layer gathering process 60. In the adhesive layer forming process, the hydrous hydrophilic adhesive layer is spread and sandwiched between a release film and a base film while continuously feeding the release film and the base film from respective rolls to form the adhesive layer. In the heating composition filling and the adhesive layer gathering process 60, the base film is placed on the air-permeable film at its one side opposite to the adhesive layer, peripheral edges of the films are melt-bonded to form a heat-sealed peripheral edge and thus to form a pocket between the base film and the air-permeable film for containing the heating composition. At the same time, an adhesive of the adhesive layer is pushed and gathered inside the heat-sealed peripheral edge. And, the heating composition layer is formed in the pocket and sealed the pocket at the same time of the formation of the pocket.
摘要:
There is provided such a heat-generating body for warming a foot in that a heat-generating composition is used that can retain the shape thereof irrespective of the pressure inside the container bag upon using by application to a foot, a footgear or a sock. The heat-generating body of the invention for warming a foot is characterized in that it contains a heat-generating formed article causing a heat-generating reaction in the presence of air and having a shape retaining degree of 70 or more charged in a container bag constituted with a base material, a covering material and the like. Further a process is provided for producing a heat-generating body for warming a foot in that the heat generation reaction of the heat-generating composition is suppressed to prevent loss due to the heat-generating reaction during production, quality deterioration of the heat-generating composition, and other problems.
