Method for embedding fastener to seat cushion

摘要

A method for embedding a fastener in a seat cushion which is adapted to recycle a fastening piece attached to a metal mold and facilitate detachment of a fastening piece embedded in a seat cushion is disclosed. The method comprises the steps of: fitting a metal support into an elongated groove formed at a metal mold; bonding either a hook piece or a loop piece of a hook-and-loop fastener to an upper surface of the metal support via heat resistant adhesive; attaching a first mating fastening piece to the fastening piece bonded to the metal support; heating the metal mold followed by injecting foaming material consisting of resin composition, foaming agent, lubricant and stabilizer into the metal mold to form a seat cushion; removing the seat cushion from the seat cushion such that fastening piece embedded in to the seat cushion is detached from the mating fastening piece bonded to the metal mold; and attaching a second fastening piece mating with the first fastening piece embedded in the seat cushion to an inner surface of a seat cover by sewing such that the first fastening piece coincides with the second fastening piece.
