Title:
PRESS FELT
Document Type and Number:
Japanese Patent JP2004277905
Kind Code:
A
Abstract:

To provide a press felt which has excellent recovery property from compression and has a stable travel attitude.

This press felt 10 comprising a substrate 20 having MD direction fiber materials 21 and staple fibers 30 integrally interlaced with the substrate 20 is characterized in that the MD direction fiber materials 21 comprise the first twisted yarns 21A having torques in one direction and the second twisted yarns 21A having torques in the direction opposite to the direction of the first twisted yarns 21A. Since the MD direction fiber materials 21 comprise the twisted yarns, the compression recovery can be improved. Since the MD direction fiber materials 21 comprise the first twisted yarns 21A having torques in one direction and the second twisted yarns 21B having torques in the direction opposite to the direction of the first twisted yarns 21A, the slip of the felt in the CMD direction on the transfer of the felt in the MD direction can be prevented to stabilize the travel attitude.
