Abstract:
A cushion member comprising:a three-dimensional network structure (3) with an apparent density of 0.005 to 0.20 g/cm3, formed by looping a plurality of continuous filaments (2) of a thermoplastic resin with fineness of 300 to 100,000 deniers and bonding the respective contact portions of the filaments (2), the network structure (3) being solidified in a manner such that the continuous filaments (2) are moved inward from opposite surfaces in the thickness direction of the cushion member (1) to be formed and from opposite sides, depending on the product shape of the cushion member (1), as the continuous filaments (2) are looped, and a density of the opposite surfaces in the thickness direction of the cushion member (1) and a density of surfaces of the opposite sides of the cushion member (1) each becoming higher than that of an inner part of the cushion member (1).
