ABSTRACT:
A multi-layer absorbent product in a preferred embodiment includes a fibrous nonwoven top sheet, a fibrous nonwoven absorbent core layer, and a fibrous nonwoven substantially water-impervious back sheet. Each component layer or sheet is manufactured at a fiberizing station (i.e., melt spinning) and laminated together at a combining station. The preferred melt spinning apparatus is spunbond for the top sheet, meltblowing for the core layer, and a combination of spunbond and meltblowing for the bottom sheet.
