Nonwoven fabric with bonding pattern

摘要

A nonwoven fabric has multiplicity of fibers, bonded portions, and unbonded portions. The bonded portions are spaced apart from one another, each bonded portion comprises portions of the fibers that are bonded together, and each bonded portion has a thickness extending perpendicularly between opposite faces of the nonwoven fabric. Each unbonded portion comprises portions of the fibers that are not bonded together, and each unbonded portion has a thickness extending perpendicularly between the opposite faces of the nonwoven fabric. The thicknesses of the unbonded portions is greater than the thicknesses of the bonded portions. The bonded portions are sized and arranged for providing a desirable balance of properties.

主权项

1. A nonwoven fabric comprising:
a multiplicity of fibers; a plurality of bonded portions, the bonded portions being spaced apart from one another, each bonded portion comprising portions of the fibers that are bonded together, and each bonded portion having a thickness extending perpendicularly between opposite faces of the nonwoven fabric; a plurality of unbonded portions, each unbonded portion comprising portions of the fibers that are not bonded together, and each unbonded portion having a thickness extending perpendicularly between the opposite faces of the nonwoven fabric; the thicknesses of the unbonded portions being greater than the thicknesses of the bonded portions; and the bonded portions being sized and arranged in a pattern configured so that the unbonded portions occupy more than 5.55 times as much space as the bonded portions in a plan view of an area of a face of the opposite faces of the nonwoven fabric, wherein the area contains more than one hundred of the bonded portions.
