Abstract
A multi-denier non-woven fabric suitable for use as a body side liner in disposable absorbent products such as diapers, sanitary napkins, underpads, surgical dressings, tampons, and the like. The multi-denier non-woven fabric is made from an interconnected network thermoplastic polymer fiber elements comprising a homogeneous blend of high denier and low denier fibers having a denier in a range of from 2 to 15 denier, wherein the high denier fiber elements and the low denier fiber elements differ by at least one denier.
Claims18
An absorbant product comprising a body fluid-impermeable backing sheet, a layer of absorbent material on said backing sheet, and a soft, body fluid-permeable, body contacting, body side liner overlying said absorbent material;
- said body side liner being a non-woven fabric comprising an interconnected network thermoplastic polymer fibers, said fibers further comprising a homogeneous blend of high denier staple fibers and low denier staple fibers in a range of from 2 to 15 denier, wherein the high denier staple fibers and the low denier fibers staple differ by at least one denier and wherein the high denier staple fibers are present in the blend in an amount of from 10 to 90% and the low denier staple fibers are present in the blend in an amount of from 90 to 10%, wherein the high denier fibers have a denier in a range of from 4 to 15 and the low denier fibers have a denier in a range of from 2 to 4.
An absorbent product having a body contacting, body side liner and an underlying absorbent core wherein the body side liner comprises a multi-denier non-woven fabric formed from an interconnected network thermoplastic polymer fibers, said fibers further comprising a homogeneous blend of high denier fibers and low denier fibers in a range of from 2 to 15 denier, wherein the high denier fibers and the low denier fibers differ by at least one denier and wherein the high denier fibers are present in the blend in an amount of from 10 to 90% and the low denier fibers are present in the blend in an amount of from 90 to 10%, wherein the high denier fibers have a denier in a range of from 4 to 15 and the low denier fibers have a denier in a range of from 2 to 4.
