<p><P>PROBLEM TO BE SOLVED: To provide a press felt for papermaking, which prevents rewetting phenomena and is excellent in smoothness, abrasion resistance and resistance to compression fatigue. <P>SOLUTION: The press felt 10 includes substrate 30 and a batt layer having a wet paper side layer 20. The wet paper side layer 20 has a substrate side batt layer 22, and napped fiber bundles 50 are formed in the substrate side batt layer 22. A core-sheath conjugate fiber 41 is subjected to needle punching and a part of a sheath component of the core-sheath conjugate fiber 41 is melted by heat treatment. Thereby, fibers are melted in columnar form to each other to form the napped fiber bundle 50. As a result, the substrate side batt layer 22 becomes dense and movement of water content of a press side batt layer 23 to wet paper side is prevented and rewetting phenomena is suppressed and abrasion resistance and resistance to compression fatigue of the felt 10 are improved by napped fiber bundles 50 melted in columnar form. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
