NETWORK STRUCTURE CUSHIONING BODY AND PRODUCTION THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a cushioning body of a three-dimensional network structure of good appearance and good feeling. SOLUTION: The objective network cushion 1 comprises the main cushion body 3 having the three-dimensional random loop network structure and the cover fiber layer 4 for covering the cushioning main body 3 and the like. The cushioning main body 3 has the three-dimensional structure of a plurality of continuous lines 2 made of a thermoplastic resin with a thickness of 300-100,000 deniers so that individual lines may be bent to loops and fused at the contacting points with each other with an apparent density of 0.005-0.2 g/cm3. The cover fiber layer 4 is prepared by blowing thermoplastic fibers thinner than the continuous lines 2 in the cushioning main body 3 from a spray gun or the like to the surface of the cushioning main body 3 so that the thinner fibers may be entangled to continuous line bodies 2.
