P.F.-593 ABSTRACT OF THE DISCLOSURE A nonwoven hospital sponge material has been provided comprising a layered fabric having an inner core of a substan- tially hydrophilic material disposed adjacent at least one outer or surface layer or between a pair of outer layers of a substantially hydrophobic material, said sponge material being bonded by passing the material through rolls engraved in a pattern of lands and grooves in such a way that a repeating pattern of three degrees of compression are imposed therein high compression, intermediate compression and, little or no compression. A nonwoven fabric bonded in this manner becomes more absorbent, loftier, has good surface integrity and does not adhere to the wound surface, when the nonwoven sponge material is then compacted subsequent to the bonding step. This thusly constructed, rather lightweight nonwoven material, produces a relatively inexpensive and disposable hospital sponge and dressing material having all of the desirable features of the more expensive woven materials commonly used today.
