Title:
NET-LIKE STRUCTURE HAVING EXCELLENT COMPRESSION DURABILITY
Document Type and Number:
WIPO Patent Application WO/2014/132484
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a net-like structure that has a small repeated compression residual strain, a great hardness retention rate after repeated compression, and excellent repeated compression durability.
This net-like structure is a three-dimensional random-loop-bonded structure obtained by meandering a continuous linear body that is made of a polyester-based thermoplastic elastomer and that has a fineness of 100 dtex or more and 60000 dtex or less, there by forming random loops, and bringing the loops into contact with one another in a molten state, wherein the three-dimensional random-loop-bonded structure has an apparent density of 0.005g/cm3 to 0.20g/cm3, a 50% constant displacement repeated compression residual strain thereof is 15% or less, and a 50% compression hardness retention rate thereof after 50% constant displacement repeated compression is 85% or more.
