Definitions

  • the present invention relates to absorbent disposable articles such as sanitary napkins, panty liners, incontinence products, sweat pads, breast pads and baby diapers.
  • absorbent disposable articles such as sanitary napkins, panty liners, incontinence products, sweat pads, breast pads and baby diapers.
  • Such articles comprise the elements of a liquid pervious topsheet, a backsheet and an absorbent core intermediate said topsheet and said backsheet.
  • the topsheet, backsheet and core may be selected from any of the known types of these components provided that they meet the desired comfort and protection performance requirements and conditions noted below and in the apended claims.
  • the topsheet - if present - should have good liquid retention to maintain a dry surface and thereby keep the skin of the wearer dry
  • the absorbent core needs to provide enough absorbent capacity and allow the flow of vapour and/or air through it and the backsheet should prevent wet through (liquid permeability) to retain the absorbed fluid while being sufficiently breathable
  • the individual elements are joined, preferably using techniques such that the final product has the desired comfort and performance level
  • Suitable monolithic films include Hytrel (TM), available from DuPont Corporation, USA, and other such materials as described in Index 93 Congress, Session 7A "Adding value to Nonwovens", J-C. Cardinal and Y. Trouilhet, DuPont de Nemours international S.A, Switzerland.
  • the elements and layers thereof may be joined by any means known in the art for affixing two adjacent layers of material, such that the layers are directly attached to one another or directly attached to one another via the joining means.
  • Suitable joining means include adhesive, fusion bonding, ultra sonic bonding, stitching, heat (e.g. thermobonding by welding fibers at intersections or melting a polymer to attach fibers or films to each other), embossing, crimping, pressure bonds, dynamic mechanical bonds or combinations thereof.
  • the preferred means of joining is adhesive.
  • Suitable adhesives include non pressure sensitive and cold adhesives.
  • the adhesive may be applied by any means known in the art such as spiral application, slot coating, spraying, spiral spraying, curtain coating, contact coating and printing, provided that the adhesive does not substantially affect the breathability and other functions of the elements of the article.
