Document Type and Number:

WIPO Patent Application WO/2008/053797

Kind Code:

A1

Abstract:

A wet paper conveyance belt (1) comprises a wet paper side layer (31) containing hydrophilic fibers (30), and a machine side layer (32). A basic cloth (33) provided in the belt is composed by laminating a first woven cloth (34) arranged on the wet paper (W) side, and a second woven cloth (35) arranged on the press roll (10) side. A part of the hydrophilic fibers (30) is exposed to the surface (37) of the wet paper side layer (31). The weft (36) of the first woven cloth (34) and the second woven cloth (35) is a yarn of low water absorption coefficient. When the hydrophilic fibers (30) are formed in the wet paper side layer (31) of the belt (1) by needle punch, the dimensional extension of the belt width due to water absorbing action of the hydrophilic fibers (30) can be suppressed.
