Cushion Manufacturing Method and Cushion

摘要

A method of manufacturing a cushion and a cushion structure are disclosed. The manufacturing method includes employing a first sheet structure that is the cross-linked foamed polyethylene (PE) or cross-linked foamed polypropylene (PP) in material with the first sheet structure serving as an inner layer and an outer layer of the cushion structure. The method further includes crushing PU foam and adding an adhesive to the crushed PU foam before compressing the crushed PU foam and the adhesive to a second sheet structure, which is called “synthetic foam” functioning as an intermediate layer of the cushion structure. The multi-layer cushion structure may be prepared after having the outer layer, the intermediate layer and the inner layer integrated together using laminating, before being placed in an oven for heating until the inner layer and the outer layer are tendered and in a shape-mold of a molding machine for pressurizing.

1. A method of manufacturing a cushion, comprising:
employing a first sheet structure that is the cross-linked foamed polyethylene (PE) or cross-linked foamed polypropylene (PP) in material with a foaming ratio ranging from 3-30 and 3-10 millimeters in thickness, wherein the first sheet structure functions as an outer layer of the cushion; crushing a PU foam and adding an adhesive to the crushed PU foam before compressing the crushed PU foam and the adhesive to a second sheet structure, which is called “synthetic foam” functioning as an intermediate layer; reusing the cross-linked foamed PE or the cross-linked foamed PP with the foaming ratio standing ranging from 3-30 and 3-30 millimeters in thickness as an inner layer; integrating the outer layer, the intermediate layer and the inner layer into a multi-layer structure using laminating; and placing the multi-layer structure in an oven and heating the multi-layer structure until the inner layer and the outer layer have been tendered before placing the multi-layer structure with the tendered inner layer and the tendered outer layer in a shape-mold of a molding machine, which pressurizes and let the shaped structure cooled down to the cushion with curvature to be suitable for an user's waist, neck, back and head support.
