Abstract
Absorbent structures for diapers are provided, comprising, immobilized onto a supporting sheet, an absorbent layer with absorbent material containing superabsorbent polymer particles and therein, in the front region, a first and a second substantially longitudinal channel, each being free of said superabsorbent polymeric particles, for improved fit and/or performance throughout the use thereof.
Claims20
An absorbent structure, comprising:
- a supporting sheet and an absorbent layer of absorbent material comprising a superabsorbent polymer material, said absorbent layer being supported by and immobilized on said supporting sheet;
- and
- said absorbent layer having:
- a transverse dimension and an average width W, a longitudinal dimension and average length L, and a height dimension;
- a first longitudinally extending side portion on one side of a longitudinal axis and a second longitudinally extending side portions on the other side of the longitudinal axis;
- a front region, back region and therein between a crotch region, each arranged sequentially in said longitudinal dimension;
- and
- at least a first continuous, substantially longitudinally extending channel and a second continuous, substantially longitudinally extending channel that are substantially free of said superabsorbent polymer material and extending through the height of said absorbent layer, said first channel being present in said first side portion's front region only and said second channel being present in said second side portion's front region only, and
- a further channel, wherein the further channel is at least present in the crotch region.

An absorbent structure comprising:
- a supporting sheet and an absorbent layer of absorbent material, the absorbent material comprising a superabsorbent polymer material and a cellulosic material, said absorbent layer being supported by and immobilized on said supporting sheet;
- and
- said absorbent layer having:
- a transverse dimension and an average width W, a longitudinal dimension and average length L, and a height dimension;
- a first longitudinally extending side portion on one side of a longitudinal axis and a second longitudinally extending side portions on the other side of the longitudinal axis;
- a front region, back region and therein between a crotch region, each arranged sequentially in said longitudinal dimension;
- at least a first continuous, substantially longitudinally extending channel and a second continuous, substantially longitudinally extending channel that are substantially free of said superabsorbent polymer material and extending through the height of said absorbent layer, said first channel being present in said first side portion's front region only and said second channel being present in said second side portion's front region only, and at least one of the first and second channels comprise an average length L′ that is at least 10 mm;
- and
- a further channel being at least present in the crotch region and having a length greater than the length of the average length L′.
