Abstract
A low permeability dryer fabric and method are disclosed which include a helical dryer fabric comprised of helix strips (12) whose winding arcs (16) are intermeshed and joined together by a composite pintle (A) to define a pintle joint. The composite pintle includes a polyester core (B) and an outer low-melt polymeric sheath (C) which has been heat softened and deformed and exhibits a profile (30) which occupies void areas in the mesh of the helical fabric in the area of the pintle joint.
