Method for preparing fabric-integrated cross-linked foamed product

摘要

The present invention relates to a method for manufacturing a fabric-integrated cross-linked foamed product, comprising the steps: preparing a mold having a cavity; filling the cavity of the mold with a molding material in an amount greater than the volume of the cavity of the mold; pressurizing and heating the mold; releasing pressure before the molding material of the mold begins to be cross-linked after having reached the softening point by the applied heat, and opening the mold; completely removing the molding material other than the molding material charged in the cavity of the mold, of the molten molding material in the opened mold; placing fabric on the upper surface of the mold the cavity of which is filled with the molding material; pressurizing and heating the mold to cross-link the molding material in contact with the fabric; and releasing pressure and rapidly opening the mold to foam the cross-linked molding material in contact with the fabric.

1. A method of manufacturing a fabric-integrated cross-linked foamed product, comprising:
preparing a mold having a cavity engraved in an arbitrary shape; filling the cavity of the mold with a molding material in an amount greater than a volume of the cavity of the mold; pressurizing and heating the mold; releasing pressure between when the molding material of the mold reaches a softening temperature by applied heat and when the molding material begins to be cross-linked, and opening the mold; completely removing the molding material other than the molding material charged in the cavity of the mold, of the melted molding material in the opened mold; placing fabric on an upper surface of the mold having the cavity filled with the molding material; pressurizing and heating the mold so that the molding material in contact with the fabric is cross-linked; and releasing pressure and rapidly opening the mold so as to foam the cross-linked molding material in contact with the fabric.
