Polyethylene-based thermoplastic resin, polyester-based thermoplastic, which has a longitudinal direction corresponding to the extrusion direction, a transverse direction orthogonal to the extrusion direction, and a thickness direction, by forming continuous loops by partially welding the continuous filaments at random. It is a three-dimensional crosspiece structure made of an elastomer or a mixture of a polyethylene-based thermoplastic resin and a polyethylene-based thermoplastic elastomer, the rebound resilience of the three-dimensional crosspiece structure is 13 cm or more, and the hysteresis loss does not exceed 34%. %, And the thermal elongation before and after the dry hot air test is 0 to 8% in the longitudinal direction. Provided is a three-dimensional crosspiece structure that has hysteresis loss and elasticity suitable for the characteristics of the human body and does not shrink due to high-temperature disinfection. |
