Title:
おむつ及びパッドにおける脚部カフスの疎水性の最適化のためのスパンボンドウエブへの細密繊度繊維の局部的適用
Document Type and Number:
Japanese Patent JP3761896
Kind Code:
B2
Abstract:
A disposable absorbent article that effectively prevents the leakage of body fluids beyond its confines. The article of the present invention comprises a body having a fluid-impermeable backsheet, an intermediate, fluid-absorbing core, and a fluid-permeable topsheet. A pair of leg cuff assemblies is attached to the body. Each assembly comprises a cuff standing portion and a cuff base portion. The assemblies are composed of two hydrophobic nonwoven layers. A first layer is composed of a spunbonded web and a second layer is composed of a meltblown fiber. The first layer extends from the free, unattached end of the cuff standing portion to the distal edge of the article defining the leg opening. The second layer is provided where needed and in weights as needed to provide maximum assembly hydrophobicity with a minimum use of material. This construction allows the cuff assemblies to form fluid-impermeable dams which prevent passage of body fluid beyond the article along its leg hole sides.
