Fibrous Network Structure Having Excellent Compression Durability |
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 decitex and not more than 60000 decitex, and by making each loop mutually contact in a molten state, wherein the network structure has an apparent density of 0.005 g/cm 3 to 0.20 g/cm 3 , 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. |
