NETWORK STRUCTURE WITH EXCELLENT LIGHTWEIGHTNESS

摘要

PROBLEM TO BE SOLVED: To provide a network structure having high cushioning performance while being lightweight.SOLUTION: A network structure is a three-dimensional random loop joined structure that is obtained by twining continuous filaments made of polyolefin-based thermoplastic elastomer including at least one kind or more of polyolefin-based thermoplastic elastomer and ethylene vinyl acetate copolymer-based thermoplastic elastomer having a fiber diameter of 0.1 mm to 3.0 mm to form random loops and bringing the loops into contact with each other in a molten state. The network structure has a tensile strength of 0.15 Mpa to 3.0 MPa.
