Abstract
Official abstract text for this publication.
A filtering face-piece respirator 10 that has a harness 14 and a mask body 12 . The mask body 12 includes a support structure 16 and a filtering structure 18 . The support structure 16 contains an auxetic mesh 20 that has been molded into an intended cup-shape configuration, and the filtering structure 18 contains a filtration layer 42 for removing contaminants from the ambient air. The use of an auxetic mesh 20 in the support structure 16 provides more uniformly-sized openings 26 in the mesh 20 and reduces opportunities for mesh overlapping and mesh distortion.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of making a filtering face-piece respirator, which method comprises: (a) molding an auxetic mesh into an intended configuration for use in a mask body; (b) supporting a filtering structure adjacent to the molded auxetic mesh; and (c) joining a harness to the mask body. 2. The method of claim 1 , wherein the auxetic mesh has open spaces that are defined by polymeric strands, and wherein the mesh is molded into a cup shape.…
