製造方法の改良に関する。Detailed Description of the Invention (Industrial Application Field) The present invention relates to a method for manufacturing cushion materials used for automobile seats, and in particular, to a method for producing cushion materials made of fiber material in the center of the surface of a core made of urethane resin. The present invention relates to an improvement in a method for producing a cushion material provided with a surface material having high elasticity.

うにしたものが開発され、実用化されている。(Prior Art) Generally, cushioning materials for automobile seats are made from foam-molded urethane resin, but urethane resin has low breathability, so it cannot sufficiently absorb the perspiration of the occupant. There is a disadvantage that the surface is sticky and causes discomfort to the seated person. For this reason, the core is made of urethane resin, and a highly breathable surface material made of fiber material is provided on the surface of the core.
A surface material that allows the perspiration of a seated person to escape due to its breathability has been developed and put into practical use.

いうものが知られている。 As a method for producing such a cushion material, for example, as disclosed in Japanese Patent Application Laid-Open No. 60-64841, first, a fiber material is made from a fiber material using a sealing material such as paper that does not allow urethane resin to pass through. The surface material is melt-sealed. Next, this melt-sealed surface material is applied to the inner contour of a urethane resin foaming mold, and the urethane resin raw material is injected into the mold from the back side of the surface material and foamed, thereby molding it integrally with the surface material. It is known that the fusing material is then destroyed by mechanical treatment such as punching until it becomes air permeable.

It is not possible to partially provide a surface material in the center of the core surface, as in the case of
In addition, after removing the core that is integrated with the surface material from the urethane resin foam mold, a separate step is required to mechanically destroy the sealing material that fuses and seals the surface material, which increases the number of manufacturing steps. be.

The manufacturing method has the following configuration. First, the surface material is coated with a hot melt film having a melting point below the curing temperature of the urethane resin on the surface of the surface material to be joined to the core, and the remaining surface with a melting point below the curing temperature of the urethane resin. Cover each with polyvinyl acetate film and seal. After setting this sealed surface material at a predetermined position in the urethane resin foaming mold so that the polyvinyl acetate film is in contact with the inner surface of the urethane resin foaming mold, the urethane resin raw material is placed inside the urethane resin foaming mold. Inject and foam. Next, by heating the urethane resin foam mold to a temperature higher than the curing temperature of the urethane resin, the urethane resin is cured, the hot melt film is melted and the core and the surface material are bonded together, and the polyacetic acid The vinyl film is torn from the center due to thermal contraction caused by the heating and shrinks toward the periphery, thereby exposing the surface material.

Each piece is covered and sealed with a vinyl film, so when the urethane resin raw material is injected into the foam mold and foamed, the urethane resin will not penetrate into the fiber material of the surface material or adhere to the surface of the surface material. without compromising breathability. Furthermore, since the surface material is sealed with a film and the urethane resin does not penetrate, the surface material can be partially provided in the center of the core surface, and its shape can be set as appropriate. .

る。 In addition, in the curing process in which the foam mold is heated to harden the urethane resin after injection and foaming of the urethane resin raw material, the polyvinyl acetate film breaks from the center due to heat shrinkage and shrinks toward the periphery. At the same time, the surface material is automatically exposed and the hot melt film is melted to bond the urethane resin core to the fiber material surface material, so of course the process of bonding the core and surface material after demolding is possible. In addition, the process of destroying the film, which corresponds to the process of destroying the sealing material required in the conventional manufacturing method, is no longer necessary, and the manufacturing process can be simplified.
