Abstract
A press felt for papermaking comprises a base body, a fibrous assembly, and a three-dimensional knitted fabric within the interior of the felt. The base body and the knitted fabric may be in contact, or, for improved adhesion between the base body and the knitted fabric, a fibrous assembly may be disposed between the base body and the knitted fabric. Excellent compression recoverability and sustainability may be obtained.
