An on-machine-seamable papermaker's fabric has a base structure 50 which is a flattened array 30 of spirally wound multicomponent yarn 16. The flattened array 30-has two layers, two sides, a length, a width and two widthwise edges 32. In each turn of the spiral winding, the multicomponent yarn 16 has a substantially lengthwise orientation and is joined side-by-side to those adjacent thereto by a fusible thermoplastic material in each of the two layers. The multicomponent yarn forms seaming loops 36, along the two widthwise edges 32. At least one layer of staple fiber material is needled into one of the two sides of the base structure 50 and through_ the two-layers. |
