Abstract
A wet paper web transfer belt () has a wet paper web-side layer (), including a hydrophilic fibrous body (), and a machine-side layer (). A base fabric () disposed in the belt comprises a first woven fabric (), disposed on a wet paper web (W) side, and a second woven fabric () disposed on a press roll () side, and the first woven fabric () and the second woven fabric () are stacked together. A portion of the hydrophilic fibrous body () is exposed on a surface () of the wet paper web-side layer (). The first woven fabric () and the second woven fabric () include weft yarns () made of a material of low water absorptivity. When the hydrophilic fibrous body () is formed in the wet paper web-side layer () of the belt () by needle punching, an increase in the widthwise dimension of the belt due to the absorption of water by the hydrophilic fibrous body () is reduced.
