Abstract (en)
[origin: WO0139880A1] The invention relates to an improved intermediate absorbent structure with an integrated air permeable fluid barrier, said structure intended to be included inside at least one external layer in the finished absorbent article and intended to eliminate a need for a secondary fluid barrier between the absorbent core and the external layer. Said structure is manufactured in the form of a continuous web that can be converted into disposable absorbent articles. The invention comprises (a) an upper layer that is liquid permeable, (b) a lower layer with a hydrohead greater than 8 cm and an air permeability less than 1000 m/s at 196 Pa, and (c) an intermediate layer of absorbent material dispersed between the upper layer and the lower layer. Preferred embodiments include intermediate structures where the lower layer comprises a composite of fine fibers and continuous filaments.
