<p>A papermaking seamed felt 10 of the present invention comprises a base layer 30 having a seam part, a wet paper web side batt fiber layer 20 formed on the wet paper web side surface of said base layer, and a press side batt fiber layer 21 formed on the press side surface thereof, wherein said wet paper web side batt fiber layer 20 having a core-in-sheath fiber 41 comprising a core member made of high-molecular-weight nylon with an absolute viscosity of 80mPa·s or more and a sheath member made of nylon with a lower melting point than the core member. A net-shaped fiber layer is formed with melted sheath members of the core-in-sheath fiber 41, which makes the wet paper web side batt fiber layer 20 dense. As a result, the wet paper web side batt fiber layer 20 works as a barrier to block water within the press side layer from moving to the wet paper web side, thereby preventing rewetting. Further, the felt acquires a balanced combination of smoothness, resistance to shedding, abrasion, and compression fatigue by providing the core member of the core-in-sheath fiber 41 with high viscosity, i.e. by using high-molecular-weight nylon.</p> |
