Abstract
Oriented woven furniture support materials made in part from elastomer monofilament and in part from yarn 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 weaving of the elastomer in a first direction and the yarn in a second direction perpendicular to the first direction followed by heat-setting of the woven material.
Claims26
A furniture support material in a woven configuration comprising crossed strands in a first direction and in a second direction perpendicular to the first direction, wherein the strands in the first direction comprise oriented thermoplastic elastomer monofilament selected from the group consisting of copolyetheresters, polyurethanes and polyesteramides, and the strands in the second direction comprise yarn, which crossing strands are affixed 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.
