The present invention aims to provide a net-like structure which has a small residual strain after repeated compression and a high hardness retention after repeated compression, and is excellent in repeated compression durability.nn n n The mesh structure is a three-dimensional irregular loop formed by bending a continuous linear body composed of a thermoplastic elastic resin with a fiber degree of 100 dtex or more and 60,000 dtex or less, and making each loop contact with each other in a molten state. Joint structure, apparent density is 0.005g / cm 3 ~ 0.20g / cm 3 , 50% fixed displacement and repeated compression residual strain is 15% or less, 50% fixed displacement and repeated compression after 50% compression hardness retention 85% or more, the thermoplastic elastic resin is at least one selected from the group consisting of a polyolefin-based thermoplastic elastomer, an ethylene-vinyl acetate copolymer, a polyurethane-based thermoplastic elastomer, and a polyamide-based thermoplastic elastomer. 1 species. |
