LOCALIZED APPLICATION OF FINE DENIER FIBERS ONTO A SPUNBONDED WEB FOR OPTIMIZATION OF LEG CUFF HYDROPHOBICITY IN DIAPERS AND PADS

摘要

A disposable absorbent article (26) that effectively prevents the leakage ofbody fluids beyond its confines. The article of the present inventioncomprises a body (28) having a fluid-impermeable backsheet (34), anintermediate, fluid-absorbing core (32), and a fluid-permeable topsheet (30).A pair of leg cuff assemblies (46, 46') is attached to the body. Each assemblycomprises a cuff standing portion (48, 48') and a cuff base portion (50, 50').The assemblies are composed of two hydrophobic nonwoven layers. A first layer(54, 54') is composed of a spunbonded web and a second layer (56, 56') iscomposed of a meltblown fiber. The first layer extends from the free,unattached end (58, 58') of the cuff standing portion (48) to the distal edge(60, 60') of the article defining the leg opening. The second layer isprovided where needed and in weights as needed to provide maximum assemblyhydrophobicity with a minimum use of material. This construction allows thecuff assemblies to form fluid-impermeable dams which prevent passage of bodyfluid beyond the article along its leg hole sides.
