The optimized triple-layer structure of Dynapulp is specifically designed to meet the demanding requirements of pulp dewatering. Dynapulp provides high dewatering capacity as well as good retention of fibers. Even though it is a relatively thin fabric, it has an extended lifetime due to the high wear volume created by the weave design.

The thin fabric design minimizes water carryover and the fine upper side reduces fiber loss due to its high mesh, while the robust under side contributes to its long lifetime.

Dynapulp fabrics are produced with woven seams or pin seams.
