  "abstract": "A structure for use in industrial fabrics such as paper machine clothing and engineered fabrics is disclosed. The structure includes axially and radially elastic hollow members, 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.",
  "claims": [
    "1. A compressible resilient industrial fabric, wherein the fabric includes a structure having an original thickness, the structure comprising: a laminated structure further comprising; a plurality of substantially parallel cross-machine direction (CD) yarns; a plurality of substantially parallel machine direction (MD) yarns; and a plurality of substantially parallel hollow elastic members in CD and/or MD; a first layer of the parallel yarns running in either the CD or the MD direction; a second layer of the hollow elastic members on one side of the first layer, the second layer's hollow elastic members running in the CD or MD direction different from that of the first layer; 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 fabric is under a compressive load, and wherein the hollow elastic members are elastic in their thickness or radial direction and length or axial direction such that under the compressive load the hollow elastic members stretch and compress to conform to the nesting and the structure 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.",
    "2. The fabric of claim 1 wherein the number of yarns in the third layer is less than the number of yarns in the first layer.",
    "3. The fabric of claim 1 wherein the hollow elastic members of the second layer are orthogonal to those of the first and third layers.",
    "4. The fabric as claimed in claim 1, wherein the hollow elastic member is selected from the group consisting of: a monofilament, a multifilament, a plied monofilament or multifilament, a wrapped member of different materials, a knitted member, a twisted member, a multicomponent member, and a braided member.",
    "5. The fabric as claimed in claim 1, wherein the hollow elastic member is selected from the group consisting of: a polyurethane and rubber.",
    "6. The fabric as claimed in claim 1, wherein the hollow elastic member is selected from members having a cross-section of differing geometric configurations.",
    "7. The fabric as claimed in claim 6, wherein the hollow elastic member is selected from the group consisting of: circular, non-circular, square, rectangular, triangular, elliptical, polygonal, trapezoidal and lobate.",
    "8. The fabric as claimed in claim 1, wherein the hollow elastic member has one or more holes running along a length or axial direction thereof.",
    "9. The fabric as claimed in claim 8, wherein the one or more holes are selected from the group consisting of: circular, non-circular, square, rectangular, triangular, elliptical, trapezoidal, polygonal, and lobate.",
    "10. The fabric of claim 1 wherein the layer of hollow elastic members is inside a double layer construction.",
    "11. The fabric of claim 1 wherein the fabric is selected from the group of fabrics including: paper machine clothing; a forming fabric; a press fabric; a dryer fabric; a through air dryer fabric; a shoe press belt base; a calendar belt base; an engineered fabric base; a transfer belt base; a belt used in the production of nonwovens by processes such as airlaid, melt blowing, spunbonding, and hydroentangling; and an industrial process belt such as a textile finishing belt."

  "description_excerpt": "The present invention relates to structures for use in industrial fabrics such as paper machine clothing and engineered fabrics. More specifically, the structures include hollow elastic members, which may be compressible in a thickness or radial direction and resilient in a length or axial direction, and relatively inelastic functional yarns in various patterns. Such structures have a high degree of both compressibility under an applied normal load and excellent recovery (resiliency or spring back) upon removal of that load.\n\nIndustrial fabrics means an endless structure in the form of a continuous loop such as one used as a forming, press or dryer fabric (paper machine clothing or PMC) as well as a process belt such as a shoe press, calendar, or transfer belt used on a paper machine. Industrial fabrics also means a fabric used in textile finishing processes. Industrial fabrics also include other endless belts where a high degree of compressibility and resiliency is required.\n\nWhile the discussion herein concerns for the most part the papermaking process in general, the application of the invention is not considered limited thereto.\n\nIn this regard, during the papermaking process, for example, a cellulosic fibrous web is formed by depositing a fibrous slurry, that is, an aqueous dispersion of cellulose fibers, onto a moving forming fabric in a forming section of a paper machine. A large amount of water is drained from the slurry through the forming fabric, leaving the cellulosic fibrous web on the surface of the forming fabric.",
