Abstract
Disclosed are the cut edges of an absorbent fabric comprising at least 45% and less than about 90% cellulosic or natural fibers, and a fusible component being stabilized by fusing the fusible component with an arrangement of spaced lines or spaced areas extending from the cut edges, and optionally over the entire absorbent fabric.
Claims23
A process for stabilizing cut edges of an absorbent fabric containing at least about 45%, and less than about 90% cellulosic or natural component, and a fusible component present or added at least within a margin along the cut edges, comprising the steps of
- intermittently fusing said margin by applying heat and pressure to said margin to melt the fusible component in discrete fused areas extending at least along, across or at angle to the cut edges, and
- maintaining free areas between the discrete fused areas substantially free of fusing,
- wherein the fused areas transition in a sloping and progressively less fused periphery toward the free areas,
- wherein said margin optionally extend over substantially the entire surface of the fabric,
- wherein the discrete fused areas comprise less than about 33%, of said margin,
- wherein the free areas comprise at least about 50% of their original thickness, and
- wherein the fabric maintains greater than 50% of its overall original thickness.
