Abstract

PURPOSE:To manufacture a cushion material, which is not returned due to crimping and has excellent impact resilient force, by dispersing a conductive filler to a crimped and processed filament short-fiber aggregate and partially welding the aggregate and the filler mutually through high-frequency induction heating. CONSTITUTION:A conductive filler (such as metallic powder such as iron powder, metallic powder mixed with a resin, metallic powder coated with the resin, etc.) is dispersed uniformly to a crimped and processed filament short-fiber aggregate, said aggregate is pressure-welded by a pressure-welding roll, the conductive filler is heat-generated through high-frequency induction heating, and the conductive filler and the aggregate are welded partially, and pressed down by the pressure-welding roller, thus manufacturing a cushion material. Only the conductive filler section is heated partially, thus resulting in no return due to crimping of a crimped filament through heating, then preventing the lowering of the modulus of impact resilience. Cushioning properties are improved by a spring effect through crimping processing, and the cushion material is fitted to a blank for a bed, a seat, etc.

In recent years, instead of cushioning materials using urethane foam, crimped filament short fibers made of polyethylene terephthalate (hereinafter abbreviated as PET), nylon, polypropylene vinyl chloride, etc., have been crimped into a spring structure. Cushioning materials made by intertwining and partially joining together with adhesives have good rebound resilience, and are therefore used in large quantities as cushioning materials for pets, sheets, etc. As a method for joining these crimped short filament fiber aggregates without fraying, conventionally, the crimped filament short fiber aggregates were bonded to an adhesive having a melting point lower than that of the crimped short filament fibers. The powder is uniformly dispersed, and the mixture of the short filament fiber aggregate and the adhesive powder is bonded under heat at a temperature lower than the melting point of the short filament fibers and higher than the melting point of the adhesive powder, so that the mixture of the short filament fibers and the adhesive powder is bonded at the point where the adhesive powder is present. Method for adhering aggregates of short filament fibers ■ Method for adhering adhesive short filament fibers in place of the adhesive powder in method (2) above and bonding them by heating and pressing in the same way as method (2); A method of uniformly spraying a liquid adhesive onto a fiber aggregate to bond it, etc., has been adopted.

In the conventional techniques, that is, methods ① and ① above, the crimped short filament fibers are heated to a temperature higher than the melting point of the adhesive (in the form of powder or short filament fibers) to bond them. The crimping of the short filament fibers returns and the impact resilience as a cushioning material decreases. Also, when making a thick cushion layer, a considerable temperature is required in the outer layer in order to heat the center layer of the cushion layer above the melting point of the adhesive, so the crimping of the short filament fibers in the outer layer becomes increasingly necessary. This results in a loss of rebound resilience. On the other hand, it is possible to use an adhesive with a low melting point, but if an adhesive with a melting point of about 60 to 80°C is used, the above-mentioned effect of crimping the short filament fibers will be lost due to heating. Although the degree of deformation will be reduced, the heat resistance as a cushion material will be lost, and problems such as the adhesive strength will weaken due to heating and the shape of the cushion will collapse. It can no longer be used as a cushioning material for seats that require temperatures above ℃.

In the method of the present invention, the means for partially adhering the crimped filament short fiber aggregate is internal heat generation by mixing a conductive filler and high-frequency induction heating of the conductive filler. Therefore, the crimped filament hardly loses its integrity.
