Abstract: A conformable face mask for health care workers is provided. The use of elastomeric materials applied under tension helps define a plurality of gathers which facilitate the donning and positioning of the mask. An elastomeric headband maintains a comfortable and efficient seal while a similar elastomeric chin strap helps provides a pouch-like enclosure for the wearer's chin. The substantially rectangular face mask includes a plurality of horizontal stays which are individually adjustable to create a three dimensional shaped mask which defines a spaced breathing area around the wearer's nose and mouth. Additional rigidity is provided by the selected melting of horizontal bands of the filter portion of the mask.

Abstract: A hydraulically needled nonwoven pulp fiber web is disclosed. This nonwoven pulp fiber web has a mean flow pore size ranging from about 18 to about 100 microns, and a Frazier porosity of at least about 100 cfm/ft.sup.2. The web may also be characterized by a specific volume ranging from about 8 to about 15 cm.sup.3 /g. The nonwoven pulp fiber web may contain a significant proportion of low-average fiber length pulp and still have a total absorptive capacity greater than about 500 percent and a wicking rate greater than about 2 centimeters per 15 seconds. The hydraulically needled nonwoven pulp fiber web may be used as a hand towel, wipe, or as a fluid distribution material in an absorbent personal care product. Also disclosed is a method of making the hydraulically needled nonwoven pulp fiber web.
