Abstract
Cross machine stuffer yarns are used in the construction of a base fabric for a papermakers wet felt. The stuffer yarns in combination with a multiple pass heat setting process stabilize the machine direction yarns of the base fabric to provide resistance to nip rejection. Preferably a fibrous batt is needled to the base fabric to finish the wet press felt.
