Abstract
A structure for use in industrial fabrics such as paper machine clothing and engineered fabrics. 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.
Claims10
A compressible resilient industrial fabric having an original thickness, wherein the fabric comprises:
- a laminated structure comprising
- a plurality of substantially parallel cross-machine direction (CD) yarns;
- a plurality of substantially parallel machine direction (MD) yarns;
- a first layer of the parallel yarns running in either the CD or the MD direction;
- a second layer of the parallel yarns on one side of the first layer, the second layer yarns running in the CD or MD direction different from that of the first layer and comprising a plurality of 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 fabric to compact to form a planar structure in a through thickness direction when the fabric is under a compressive load,
- wherein the elastomeric yarns are elastic in their thickness or radial direction and length or axial direction such that under the compressive load the elastomeric yarns stretch and
- compress to conform to the nesting and the fabric springs back to substantially the original thickness after removal of the load, and
- wherein the fabric is formed in an endless structure in the form of a continuous loop.
