Elastic network structure excellent in quietness and hardness

摘要

PROBLEM TO BE SOLVED: To provide an elastic net-like structure excellent in the cushionability with reduced noise when the structure is compressed or recovered.SOLUTION: The net-like structure is formed of a three-dimensional random loop joint structure formed by forming random loops with winding continuous linear bodies of 100-100,000 decitex, bringing the respective loops in a fused state into contact with each other, and fusing most of the contact parts. Tanδ of the continuous linear body at the temperature of 23°C measured by a dynamic viscoelasticity measuring device is at least 0.10, and the hardness of the three-dimensional random loop joint structure when compressed by 25% is at least 10 kg/Φ200 mm.
