ABSTRACT:
A nonwoven, self-sustaining, absorbent fabric comprising a sheet of randomly arranged, intermingled cellulosic fibers has a plurality of high loft, loosely compacted regions separated from each other by highly compressed regions. An adhesive material penetrates through the compressed regions to form bonded fiber networks extending completely through the sheet, and said adhesive material only partially penetrates through said high loft regions whereby the fibers in the interiors of said high loft regions are unbonded by said adhesive so that said regions are highly absorbent. A method for manufacturing the above-described nonwoven fabric by moistening opposed surfaces of a loosely compacted, randomly oriented cellulosic fiber sheet, embossing said moistened sheet for providing a pattern in said surfaces, applying an adhesive to the patterned surfaces of the sheet and setting said adhesive.
