Abstract (en)
A felt (100) for papermaking comprises two or more bases of one type or different types and batt fibers including core-in-sheath composite fibers and integrally intertwined with one surface or both surfaces of the bases by needling. At least one of the bases is formed of twisted yarns comprising soft-twisted warp yarns or weft yarns including core-in-sheath composite fibers. The felt has a good water squeezing ability, an excellent wet paper web smoothing ability, a good compression rate, a good recovery ratio, and a good ability to sustaining the recovery ratio upon pressurization, and, in particular, an excellent fiber removal resisting ability. The felt is thus suitable for use in a high-speed papermaking machine.
