In addition, the level of performance is expected to be at steady high level all along the service life of a felt. Figure 2. With its uniform machine direction yarn structure Atrojet has far greater surface contact than conventional bases. This leads to more even pressure transmission at the press nip resulting in very steady dewatering and even CD profiles.Figure 3. Atrojet press felt. TISSUE TECHNOLOGY INTERNATIONAL53'
