A seat pad including a cushion pad 1. The cushion pad (1) includes a soft foam (2) and a beaded foam (3) embedded in the soft foam (2). The bottom surface of the cushion pad (1) is formed by the bottom surface (2f2) of the soft foam (2).

The problem of the present invention is to offer a nonwoven fabric for reinforcing foam molded articles that enables cushion materials to be efficiently foam molded by improving adhesiveness of the reinforcing nonwoven fabric to a mold.

The present invention is a nonwoven fabric for reinforcing foam molded articles, having a reinforcing nonwoven layer and at least one resin layer, wherein the reinforcing nonwoven layer and the at least one resin layer are laminated, the reinforcing nonwoven layer has a discontinuous part including a magnetic material, the at least one resin layer has a resin having softening point A of 20 C. or higher and 60 C. or lower, and the nonwoven fabric has an air permeability of 30 cc/cm.sup.2/sec or more and 300 cc/cm.sup.2/sec or less.

Embodiments of the present disclosure relate to making polyurethane foam less likely to become separated from an in-mold foamed molded product unit, the in-mold foamed molded product unit including an in-mold foamed molded product and an insert material which are integrally provided. A foamed composite molded product is configured such that a portion of an insert material is exposed to an outside of an in-mold foamed molded product, and is in contact with polyurethane foam.

A method for producing polyethylene-based resin foamed particles includes a first-step foaming process. The first-step foaming process includes: producing an aqueous dispersion by dispersing polyethylene-based resin particles in an aqueous dispersing medium in a sealed vessel, adding a carbon dioxide-containing foaming agent to the aqueous dispersion in the sealed vessel, heating and pressurizing the aqueous dispersion in the sealed vessel, and releasing the aqueous dispersion in the sealed vessel to a pressure region where a pressure is lower than an internal pressure of the sealed vessel. The foaming ratio in the first-step foaming process is 10 to 18 times. The polyethylene-based resin particles have a polyethylene-based base resin and a melting point of 105 to 125 C., a tan of 0.3 to 0.7, and a complex viscosity of 5000 to 20000 Pa.Math.s.

Polypropylene-based resin expanded particles include polypropylene-based resin particles. The polypropylene-based resin particles include a base resin that is a polypropylene-based resin mixture, wherein 100 parts by weight of the polypropylene-based resin mixture consists of 92.0 to 98.5 parts by weight of a polypropylene-based resin having a melting point of 130 C. to 155 C., and 1.5 to 8.0 parts by weight a polypropylene-based wax having a melting point of 100 C. or less. The polypropylene-based wax is a copolymer of propylene and one or more -olefins other than propylene.
