Abstract
A structure for use in a compressible resilient pad. The structure contains both axially elastomeric yarns and relatively inelastic yarns in various patterns. The structure has a high degree of both compressibility under an applied normal load and excellent recovery (resiliency or spring back) upon removal of that load.
Claims17
A compressible resilient pad, the pad having an original thickness and includes a structure comprising:
- a plurality of parallel warp yarns;
- a plurality of parallel shute yarns;
- wherein either or both of shute yarns or warp yarns are comprised of an axially elastomeric material,
- wherein the structure is a laminated structure comprising:
- a first layer of the parallel yarns running in either the warp or the shute direction;
- a second layer of the parallel yarns on one side of the first layer, the second layer's yarns running in the warp or shute direction different from that of the first layer and comprising the elastomeric yarns;
- and
- a third layer of the parallel yarns on the opposite side of the second layer as the first layer and running in the same direction as those of the first layer,
- wherein the parallel yarns of the third layer are aligned such that the parallel yarns of the third layer nest between the parallel yarns of the first layer without interfering with one another to allow the structure to compact to form a planar structure in a through thickness direction when the pad is under a pressure load;
- wherein the elastomeric yarns are elastic in their through thickness direction and length or axial direction such that under the pressure load the elastomeric yarns stretch and compress to conform to the nesting and, the structure springs back to substantially the original thickness after removal of the pressure load.
