A wet paper web transfer belt 10 comprises a base body 30, a paper side layer 20, and a machine side layer 23. The paper side layer 20 is composed of a paper contacting side batt layer 21 made of hydrophilic fibers 41 and a base body side batt layer 22 without the hydrophilic fibers 41, at least the paper contacting side batt layer 21 being impregnated with a high molecular weight elastic body 50 and at least a part of the hydrophilic fibers 41 being exposed on the surface of the paper contacting side batt layer 21. The water contained in the wet paper web remains within the paper contacting side batt layer 21 made of the hydrophilic fibers 41 with only a small amount of water moving into the base body side batt layer 22, thereby reducing dimensional changes of the belt. Further, since the water contained in the wet paper web remains within the hydrophilic fibers 41 exposed on the surface of the paper side layer 20, the belt is capable of transferring the wet paper web attached thereon while allowing smooth detachment when transferring it to the next process. |
