Absorbent article having nonwoven lateral zones
A disposable hygiene article for collecting bodily fluid having a body-facing surface, a garment facing-surface and an absorbent structure. The article may include a central fluid acquisition zone which may be substantially white, a first visually discernible lateral zone situated on one side of the central zone and a second visually discernible lateral zone situated on the opposite side of the central zone, wherein the first and second lateral zones are formed by a nonwoven material including a colored pigment.
1. An absorbent hygiene article for collecting bodily fluid, the absorbent hygiene article comprising
a topsheet having a body-faceable surface comprising a central fluid acquisition zone,
a backsheet having a garment faceable surface,
an absorbent structure situated between the topsheet and the backsheet,
a first visually discernible lateral zone situated on one side of the central fluid acquisition zone, and
a second visually discernible lateral zone situated on an opposite side of the central fluid acquisition zone,
wherein each of the first and second visually discernible lateral zones are situated above the body-faceable surface of the topsheet and are formed by a color-pigmented nonwoven material;
wherein the color-pigmented nonwoven material comprises a blend of colored pigments and thermoplastic material;
wherein the nonwoven material comprises fibers made of a polymer selected from the group comprising polyethylene, polypropylene, polyamides, and mixtures thereof; wherein the nonwoven material is made of bicomponent fibers comprising a core of polypropylene and a sheath of polyethylene; and wherein the pigment is present in the polypropylene core; and
wherein the central fluid acquisition zone is substantially white.
2. The absorbent hygiene article according to claim 1 wherein the body-faceable surface is conceptually divided in its length in two halves by a longitudinal centerline and wherein the central fluid acquisition zone substantially encompasses the longitudinal centerline so that the first lateral zone is on one side of the longitudinal centerline and the second lateral zone is on the other side.
3. The absorbent hygiene article according to claim 1 wherein the nonwoven material forming the lateral zones has an Opacity Index of a least 50%, measured at 745 nm.
4. The absorbent hygiene article according to claim 1 wherein the nonwoven material is hydrophobic.
5. The absorbent hygiene article according to claim 1 wherein the first and second visually discernible lateral zones extend to the periphery of the absorbent hygiene article.
6. The absorbent hygiene article according to claim 1 wherein the absorbent structure comprises a gradient core.
7. The absorbent hygiene article according to claim 1 wherein the color-pigmented nonwoven material comprises from about 0.3% to about 2.5%, by weight, of pigments.
8. The absorbent hygiene article according to claim 1 wherein the color-pigmented nonwoven material has an angle ω of from 220° to 310°.
9. An absorbent hygiene article for collecting bodily fluid, the absorbent hygiene article comprising
a topsheet having a body-faceable surface comprising a central fluid acquisition zone,
a backsheet having a garment faceable surface,
an absorbent structure situated between the topsheet and the backsheet,
a first visually discernible lateral zone situated on one side of the central fluid acquisition zone, and
a second visually discernible lateral zone situated on an opposite side of the central fluid acquisition zone,
wherein each of the first and second visually discernible lateral zones are situated above the body-faceable surface of the topsheet and are formed by a nonwoven material comprising a colored pigment;
wherein the nonwoven material comprises fibers made of a polymer selected from the group comprising polyethylene, polypropylene, polyamides, and mixtures thereof; wherein the nonwoven material is made of bicomponent fibers comprising a core of polypropylene and a sheath of polyethylene; and wherein the pigment is present in the polypropylene core.
