Abstract
To provide a net-like structure having excellent low resilience characteristics, cushioning properties, and durability. The net-like structure has a three-dimensional random loop bonded structure constituted of a continuous linear body made of a thermoplastic elastomer having a fiber diameter of 0.1-3.0 mm and a styrene content of 10-40 mass %, the net-like structure having an apparent density of 0.005-0.30 g/cm3 and a 40° C. compression residual strain of less than or equal to 35%.
Claims10
A net structure, comprising:
- a three-dimensional random loop bonded structure constituted of a continuous linear body comprising a thermoplastic elastomer composition;
- wherein the continuous linear body has a fiber diameter of 0.1-3.0 mm;
- wherein the thermoplastic elastomer composition has a styrene content of 10-40 mass %,
- wherein the net structure has apparent density of 0.005-0.30 g/cm3 and a 40° C. compression residual strain of less than or equal to 35%,
- wherein the thermoplastic elastomer composition is either
- (i) an alloy consisting of at least two kinds of styrene-based thermoplastic elastomers different in resin composition, or
- (ii) an alloy consisting of a styrene-based thermoplastic elastomer and a polyolefin-based thermoplastic elastomer, the polyolefin-based thermoplastic elastomer being an α-olefin copolymer resin selected from the group consisting of ethylene, propylene, and α-olefin having 4 or more carbons.
