<p>A papermaking seamed felt (10) which comprises a base layer (30) having a seam part, a wet-web-side butted fiber layer (20) formed on the wet-web-side surface of the base layer (30), and a press-side butted fiber layer (21) formed on the press-side surface of the base layer (30), wherein the wet-web-side butted fiber layer (20) comprises core-sheath composite fibers (41) formed from a core ingredient comprising a high-molecular nylon having an absolute viscosity of 80 mPa s or higher and a sheath ingredient comprising a nylon having a lower melting pint than the core ingredient. The sheath ingredient for the core-sheath composite fibers (41) melts to form a network fiber layer to make the wet-web-side butted fiber layer (20) dense. Since the wet-web-side butted fiber layer (20) hence serves as a barrier, the water contained in the press-side layer is less apt to move to the wet-web side. Thus, a remoisturization phenomenon is inhibited from occurring. Due to the use of a high-viscosity ingredient, i.e., a high-molecular nylon, as the core ingredient for the core-sheath composite fibers (41), the felt can have a well-balanced combination of surface smoothness, unsusceptibility to fiber shedding/wearing resistance, and resistance to compression fatigue.</p> |
