Abstract
This invention provides a press felt (10) for papermaking, comprising a substrate (30), a wet paper-side vat layer (20) and a press-side vat layer (23). The wet paper-side vat layer (20) comprises a wet paper contact-side vat layer (21) and a substrate-side vat layer (22). The wet paper contact-side vat layer (21) comprises a core-sheath composite fiber (41) comprising a core component of a high-molecular weight nylon having an absolute viscosity of not less than 80 mPas and a sheath component of a nylon having a lower melting point than the core component. The substrate-side vat layer (22) comprises a layer of a nylon fiber (42) free from the core-sheath composite fiber (41). The sheath component of the core-sheath composite fiber (41) is melted to render the wet paper contact-side vat layer (21) dense, and, consequently, moisture in the press-side vat layer (23) is less likely to be moved to the wet paper side, whereby a remoistening phenomenon can be suppressed. Further, since the substrate-side vat layer (22) comprises a nylon layer free from the core-sheath composite fiber, the balance among smoothness, defiber resistance, abrasion resistance, compression fatigue resistance, and water drainage is good.
