A belt (10) for shoe press comprising a shoe side layer (20), a substrate (30) formed on the our circumference of the shoe side layer (20), and a wet paper side layer (60) formed on the outer circumference of the substrate (30). The substrate (30) consists of a lattice-like material (40) formed by bonding the intersection of a warp (40A) and a weft (40B), and a thread winding layer (50) formed by winding a thread (50A) spirally. Bonding at the intersection of the warp (40A) and the weft (40B) is separated easily and friction takes place between them, but since the warp (40A) is made to wear earlier than the weft (40B), the weft (40B) does not wear in the early stage as compared with prior art. Consequently, strength and dimensional stability of the belt for shoe press are enhanced.
A shoe press belt to be disposed between press rolls and a shoe of a shoe press apparatus, comprising a base body consisting of a lattice material made by joining the crossing points of warp yarns and weft yarns and a thread layer wound in helix, a wet paper web side layer and a shoe side layer formed on a mandrel having a polished surface, characterized in that said warp yarns are so formed as to wear earlier than said weft yarns.
