Absorbent article comprising a lower acquisition and distribution system

An absorbent article comprising a topsheet, a backsheet, and a layer of absorbent material interposed between the topsheet and the backsheet, wherein the layer of absorbent material (28) comprises superabsorbent polymer. The absorbent article further comprises a lower acquisition and distribution system with at least one nonwoven or woven layer, the lower acquisition and distribution system being interposed between the layer of absorbent material and the backsheet. The absorbent article has a first zone corresponding to 800 ?m starting from and including the topsheet and extending towards the backsheet, and a second zone corresponding to 800 ?m starting from and including the backsheet and extending towards the topsheet. The amount of liquid in the first and second zone is very small as measured by the NMR test method set out herein.

20170020749 · 2017-01-26 · ·

A hydrophilized cellulose acetate tow band according to the present invention includes a crimped cellulose acetate tow band, and a hydrophilizing component having an HLB value of 16 or more. The cellulose acetate tow band includes a cellulose acetate having a degree of substitution of 2.0 to 2.6. The cellulose acetate tow band has a total denier of 10000 to 40000 and is crimped in a number of crimps of 30 to 60 per inch. The hydrophilizing component is impregnated on the cellulose acetate tow band in an amount of 0.2 to 2 weight percent relative to the cellulose acetate tow band. The hydrophilized cellulose acetate tow band may further include a textile oil, where the textile oil is impregnated on the crimped cellulose acetate tow band in an amount of 0.2 to 2 weight percent relative to the cellulose acetate tow band, in addition to the hydrophilizing component having an HLB value of 16 or more.

Absorbent article with a channel-forming area and a masking layer

An absorbent article comprising a liquid permeable topsheet, a backsheet, an absorbent core comprising an absorbent material and a core wrap is provided. The core comprises at least one channel-forming area that is substantially free of absorbent material. The absorbent article comprises a masking layer between the bottom side of the core wrap and the backsheet. The masking layer and the bottom side of the core wrap are only partially bonded to each other at their interface, the interface thus comprising a bonded portion and an unbonded portion, wherein the channel-forming area at least partially corresponds to the unbonded portion of the interface, so that when the absorbent material swells, the masking layer can decouple from the three-dimensional channels.

An Absorbent Article with Fluid Control Features
