Abstract
A paper-making press felt ( ) includes a base member ( ) and at least one batt layer ( ) laminated on the base member ( ), and is characterized in that the base member ( ) is made of a plurality of ground fabrics, and in that, of the plurality of ground fabrics, a second ground fabric (B) arranged next to a first ground fabric (A) arranged nearest to a surface ( ) on which a wet paper sheet is placed has a structure whose density is higher than or whose air permeability is lower than that of the first ground fabric (A), and can regulate water from moving from the second ground fabric (B) to the first ground fabric (A) and hence can prevent a re-wetting phenomenon effectively.
