<p><P>PROBLEM TO BE SOLVED: To provide a press felt for papermaking and a press unit for paper machine for improving water-squeezing tendency through preventing rewetting phenomena. <P>SOLUTION: The press felt 10 comprises a substrate 20, a batt layer 30 and a hydrophilic nonwoven fabric 40, and these three components are interlacingly unified by needlepunching. In this press felt, the batt layer 30 comprises staple fibers 50 and is composed of a wet paper side layer 31 and a press side layer 32, and the hydrophilic nonwoven fabric 40 is laid in the wet paper side layer 31. Owing to the hydrophilizing effect of the nonwoven fabric 40, water-migratory action to the nonwoven fabric 40 and migrated water-holding action are exerted, therefore this press felt can prevent rewetting phenomenon more effectively than conventional ones. <P>COPYRIGHT: (C)2004,JPO</p> |
