Abstract
An absorbent article having a topsheet with natural fibers and a semi-hydrophilic composition is provided. The semi-hydrophilic composition may have a wax ester and a polyglyceryl emulsifier in a ratio of between about 0.5:1 and 1.5:1. The topsheet may have a Contact Angle of between about 35° and about 100°. The topsheet may have a Fluid Strike-Through time of between about 0.5 seconds to about 18 seconds and a wicking height of between about 0 mm and about 10 mm.
Claims20
An absorbent article comprising:
- a liquid permeable nonwoven topsheet comprising:
- natural fibers;
- a first wearer-facing side and an opposing second garment-facing side;
- and
- a semi-hydrophilic wax composition disposed on the first side and the second side of the nonwoven topsheet and comprising a wax ester and a polyglyceryl emulsifier, wherein a weight ratio of the wax ester to the polyglyceryl emulsifier is between about 1.5:1 and about 0.5:1, wherein the semi-hydrophilic wax composition is distributed generally equally throughout the nonwoven topsheet on the first wearer-facing side and the opposing second garment-facing side;
- a liquid impermeable backsheet;
- and
- an absorbent core disposed at least partially between the nonwoven topsheet and the backsheet.

An absorbent article comprising:
- a liquid permeable nonwoven topsheet comprising:
- natural fibers;
- a first wearer-facing side and an opposing second garment-facing side;
- and
- a semi-hydrophilic wax composition comprising a wax ester and a polyglyceryl emulsifier disposed on the first side of the nonwoven topsheet, on the second side of the non-woven topsheet, and between the first side and the second side of the nonwoven topsheet, wherein a weight ratio of the wax ester to the polyglyceryl emulsifier is between about 1.5:1 and about 0.5:1;
- a liquid impermeable backsheet;
- and
- an absorbent core disposed at least partially between the nonwoven topsheet and the backsheet;
- and
- wherein the semi-hydrophilic wax composition is applied to the nonwoven topsheet at a rate of between about 0.5% and about 1.5% by weight of the nonwoven topsheet, wherein the semi-hydrophilic wax composition is distributed generally equally throughout the nonwoven topsheet on the first wearer-facing side and the opposing second garment-facing side.

An absorbent article comprising:
- a liquid permeable nonwoven topsheet comprising:
- natural fibers;
- a first wearer-facing side and an opposing second garment-facing side;
- and
- a semi-hydrophilic wax composition disposed on a surface of a portion of the natural fibers located on both the first side and the second side of the topsheet and comprising a wax ester and a polyglyceryl emulsifier;
- wherein a weight ratio of the wax ester to the polyglyceryl emulsifier is between about 1.5:1 and about 0.5:1, wherein the semi-hydrophilic wax composition is distributed generally equally throughout multiple layers of the nonwoven topsheet;
- a liquid impermeable backsheet;
- and
- an absorbent core disposed at least partially between the nonwoven topsheet and the backsheet.
