Abstract
The present invention relates to absorbent articles which include one or more barrier members comprising a light-weight nonwoven laminate that has been treated with a hydrophobic surface coating intended to render such components impermeable to liquids having relatively low surface tensions.
Claims20
An absorbent article comprising:
- a) a liquid pervious first topsheet having an interior surface and an exterior surface;
- b) a backsheet having an interior surface and an exterior surface wherein said backsheet is at least partially joined to said topsheet;
- c) an absorbent core disposed between said topsheet and said backsheet;
- d) a barrier member selected from the group consisting of a core cover, an outer cover, a gasketing cuff, a barrier cuff, an elasticized topsheet, and combinations thereof;
- wherein said barrier member has an interior and an exterior surface;
- wherein said barrier member comprises a nonwoven laminate, said nonwoven laminate comprising:
- i) a first continuous filaments layer,
- ii) a second continuous filaments layer,
- iii) a fine fiber layer having a basis weight of less than about 1.5 gsm and being disposed between the first continuous filaments layer and the second continuous filaments layer;
- and
- e) a hydrophobic surface coating disposed on at least one surface of said nonwoven laminate wherein said coating comprises one or more silicone polymers and wherein said coating is substantially free of aminosilicones.
