ABSTRACT:
A laminated integrally woven on-machine-seamable papermaker's fabric includes two single-layer woven fabric plies sharing a common machine-direction (MD) yarn. The common MD yarn, which is the weft yarn on the loom during the weaving of the fabric by a modified endless weaving technique, forms seaming loops which join the plies to one another at the ends thereof. The fabric may be needled with a batt of staple fiber material. During the weaving of the press fabric, solvent-removable binder yarns join the two plies, which are accordingly integrally woven. When the weaving is completed, the solvent-removable binder yarns are removed through dissolution with an appropriate solvent, yielding the laminated structure. A batt of staple fiber material may be needled into and through the laminated structure. The papermaker's fabric may be used as a forming, press or dryer fabric, or as a base for a polymer-coated, paper industry process belt, such as a long nip press, sheet-transfer or calender belt.
