Definitions

  • the sanitary napkin 10 can further include one or more additional layers 24 that are designed to enhance, modify or transfer fluid in a preferential manner.
  • additional layers include cellulosic and polymeric materials such as tissue, superabsorbents and melt blown materials. Such layers and materials are commercially available from several sources and are well known to those skill in construction of disposable absorbent articles, such as sanitary napkins, diapers and incontinent devices.
  • the sanitary napkin 10 can also include shape conforming members adapted to contort and conform the sanitary napkin 10 to a wearer's anatomy during use.
  • the cover 12 can also be treated with a surfactant to improve its hydrophilic characteristics.
  • the surfactant can include topical additions or internally applied materials like polysiloxanes.
  • the absorbent 14 can be made from other well known materials used in absorbent articles, including multiple layers of cellulose wadding, cellulose sponge, hydrophilic synthetic sponge, such as polyurethane, and the like.
  • the capacity of the absorbent 14 may be varied depending upon the intended usage of the final product.
  • a good material for the baffle 16 is a micro-embossed, polymeric film, such as polyethylene or polypropylene having a thickness in the range of from about 0.012 mm to about 1.0 mm.
  • Bicomponent films can also be used as well as woven and nonwoven fabrics which have been treated to render them liquid-impermeable.
  • Perforations can be made in many different ways, including cutting, needling, punching and the like.
  • the perforations 32 can be arranged in a narrow area or strip of the retaining layer 28 as opposed to having the perforations distributed throughout the retaining layer 28. By having the perforations 32 arranged along a narrow strip, it is possible to slow the dissipation of moisture through the material 30 and out of the chemical mixture. This can provide for a conservation of moisture within the chemical mixture, thereby increasing the life of the chemical mixture.
