<p>PROBLEM TO BE SOLVED: To provide a net-like structure that is excellent in thermal dimensional stability and productivity and is small in a change before and after a compressive residual strain test at 40°C.SOLUTION: The net-like structure is a three-dimensional random loop joint structure obtained by forming random loops by winding a continuous linear body comprising an ethylene-vinyl acetate vinyl copolymer and having a fiber diameter of 0.1 mm-3.0 mm and bringing each loop into contact mutually in a molten state, in which the apparent density is 0.005 g/cm-0.20 g/cmand the compressive residual strain at 40°C is 5%-20%.</p> |
