Abstract
Transfer belt for a paper machine, comprising a base structure ( ) and a fiber batt layer ( ) attached to the base structure and facing the fiber web. At least the fiber batt layer side of the belt is provided with a polymer matrix ( ) impregnating the fiber batt layer ( ). According to the idea of the invention, the transfer belt fiber batt layer comprises at least two fibers with different surface properties, the transfer belt surface facing the fiber web being thus provided with hydrophilic and, correspondingly, hydrophobic areas. The fibers in the fiber batt layer may differ from one another with regard to their polarity, hydrophilicity, electric charge, surface energy, friction properties, degree of fineness or porosity.
