Abstract
To improve the water squeezing function of a shoe press belt for papermaking, the wet web side layer of a main body of the belt is composed of a high molecular weight elastic material, and the wet web facing surface of the wet web side layer is made hydrophobic. Water, squeezed from the wet web under compression in a shoe press, and transferred to the surface of the wet web side layer of the belt through a felt, may be shaken off reliably before the belt is again subjected to compression.
