Abstract
An aerated latex microsized single ply hydroentangled fabric wherein a latex mixture is aerated by an Oakes foamer, and then applied to a fabric by a knife-over-roll applicator whereby the latex is worked below the surface of said fabric. The thusly sized fabric is then dried by passing it through an oven. The present invention enables the acquisition of sufficient hydrophobicity in the fabric so as to be a bacterial barrier while preserving therein comfort, drapeability, air permeability, flexibility, and hand. In addition to preserving the above properties, microsizing does not detract from sterilizability of the fabric.

A porous, breathable, liquid and bacterial barrier material comprising:
- a single ply fibrous web having a substantially froth-free face surface, a sized inner core and a substantially froth-free backing surface and, said sized inner core includes a froth size within said web disposed beneath said face surface;
- said backing surface being substantially free of said froth size, said froth size further including a plurality of micropores disposed throughout.
A porous, breathable, liquid and bacterial barrier material comprising:
- a single ply, hydroentangled nonwoven web having a substantially froth-free face surface, a sized inner core and a substantially froth-free backing surface and,
- said sized inner core includes a latex-clay froth size within said web disposed beneath said surface;
- said backing surface being substantially free of said froth size, said froth size further including a plurality of micropores ranging in size from about 10 microns to 100 microns in diameter disposed throughout.
