摘要：
The present invention provides a network structure having excellent repeated compression durability, the network structure having a low repeated compression residual strain and a high hardness retention after repeated compression.A network structure comprising a three-dimensional random loop bonded structure obtained by forming random loops with curling treatment of a continuous linear structure including a polyester-based thermoplastic elastomer and having a fineness of not less than 100 dtex and not more than 60000 dtex, and by making each loop mutually contact in a molten state, wherein the network structure has an apparent density of 0.005 g/cm3 to 0.20 g/cm3, a 50%-constant displacement repeated compression residual strain of not more than 15%, and a 50%-compression hardness retention of not less than 85% after 50%-constant displacement repeated compression.
摘要（中）：
本发明提供了具有优异的重复压缩耐久性的网络结构，该网络结构具有低的重复压缩残余应变和在重复压缩之后的高硬度保持率。 一种网状结构体，其特征在于，包括通过使包含聚酯系热塑性弹性体的连续线状结构的卷曲处理形成无规环状而具有100dtex以上且60000dtex以下的细度而得到的三维无规环状结合结构的网状结构体， 通过使每个环在熔融状态下相互接触，其中网状结构的表观密度为0.005g / cm 3至0.20g / cm 3，不超过50％的重复压缩残余应变为15％以下，50 ％压缩硬度保持率不低于85％，经过50％恒定位移重复压缩。
