Abstract
This disclosure provides for an absorbent article having an absorbent polymer material and a component comprising a hydrophilic surfactant-treated nonwoven material, and/or a wetness indicator. Various stabilizing components and methods are disclosed for stabilizing the surfactant-treated synthetic fibers in the nonwoven material so as to reduce surfactant loss during wetting, and enhance the performance of the absorbent article.
Claims19
A disposable absorbent article, comprising:
- a) a chassis comprising a liquid pervious topsheet and a liquid impervious backsheet that is at least partially joined to the topsheet;
- and
- b) an absorbent core disposed at least partially between the topsheet and the backsheet and comprising an absorbent polymer material;
- wherein the disposable absorbent article or any component thereof comprises a hydrophilic nonwoven material comprising a plurality of surfactant-treated synthetic fibers;
- the disposable absorbent article further comprising:
- c) a stabilizing component which reduces the loss of surfactant from the hydrophilic nonwoven material during wetting, the stabilizing component selected from:
- i) at least one substantially permanent hydrophilizing agent associated with the hydrophilic nonwoven material;
- ii) at least one substantially permanent hydrophobic agent independent of the hydrophilic nonwoven material, or
- iii) a combination of i) and ii).
A method of a stabilizing surfactant-treated synthetic fibers to surfactant loss during wetting, the method comprising:
- a) providing a disposable absorbent article comprising a hydrophilic nonwoven material, the nonwoven material comprising surfactant-treated synthetic fibers;
- b) combining or otherwise associating at least one substantially permanent hydrophilizing agent with the hydrophilic nonwoven material;
- and/or
- c) depositing at least one substantially permanent hydrophobic agent on a portion of the disposable absorbent article independent of the hydrophilic nonwoven material.
A disposable absorbent article, comprising:
- a) a chassis comprising a liquid pervious topsheet and a liquid impervious backsheet that is at least partially joined to the topsheet;
- b) an absorbent core disposed at least partially between the topsheet and the backsheet and comprising an absorbent polymer material;
- wherein the disposable absorbent article or any component thereof comprises a hydrophilic nonwoven material comprising a plurality of surfactant-treated synthetic fibers;
- the disposable absorbent article further comprising:
- c) a stabilizing component which reduces the loss of surfactant from the hydrophilic nonwoven material during wetting, the stabilizing component selected from:
- i) at least one substantially permanent hydrophilizing agent associated with the hydrophilic nonwoven material;
- ii) at least one substantially permanent hydrophobic agent independent of the hydrophilic nonwoven material, or
- iii) a combination of i) and ii);
- and
- d) a wetness indicator disposed between the absorbent core and the backsheet and in liquid communication with the absorbent core, the wetness indicator comprises at least one responsive color composition such that, upon wetting, a visible change occurs.
