Abstract
Oriented net furniture support materials made from thermoplastic elastomers have been found to possess a unique combination of properties including high strength, low creep and good flexibility. These furniture support materials can be made by extrusion through a pair of concentric die sets rotating transversely to one another or by weaving of monofilament.
Claims23
A furniture support material in a net configuration comprising crossed strands of oriented thermoplastic elastomer selected from the group consisting of copolyetheresters, polyurethanes and polyesteramides, which strands are bonded to each other at the points at which they cross, which furniture material has a tear resistance value of at least 0.40 joules/meter-gram/meter.sup.2, has a dead load static creep K-factor value of less than 6000 percent change in deflection-grams/meter.sup.2, has a deflection value of 1.25-7.50 cm, and has a dynamic creep K-factor value of less than 5000 percent change in deflection-grams/meter.sup.2.
