An absorbent core for use in an absorbent article, the absorbent core including a first absorbent layer comprising a first substrate, a layer of first superabsorbent polymer particles deposited on the first substrate on a deposition area and a fibrous layer of thermoplastic adhesive material covering the layer of first superabsorbent polymer particles, and a second absorbent layer comprising a second substrate and a mixed layer comprising a mixture of second superabsorbent particles and cellulosic fibers deposited on the second substrate. The first and second absorbent layers are combined together such that at least a portion of the fibrous thermoplastic adhesive material of the first absorbent layer contacts at least a portion of the mixed layer of the second absorbent layer.

대표청구항 ▼

1. An absorbent core for an absorbent article, the absorbent core comprising: a first absorbent layer comprising a first substrate, a layer of first superabsorbent polymer particles deposited on the first substrate on a deposition area, and a fibrous layer of thermoplastic adhesive material covering the layer of first superabsorbent polymer particles, wherein the layer of first superabsorbent polymer particles is substantially cellulose free; anda second absorbent layer comprising a second substrate and a mixed layer comprising a mixture of second superabsorbent polymer particles and cellulosic fibers deposited on the second substrate; the first absorbent layer and the second absorbent layer being combined together such that at least a portion of the fibrous layer of thermoplastic adhesive material of the first absorbent layer contacts at least a portion of the mixed layer of the second absorbent layer; and wherein the core has a longitudinal axis, and the first absorbent layer comprises one or more channels substantially extending in the longitudinal direction of the core, the channels being free of first superabsorbent particles and each channel being defined by continuous side wall portions; wherein in the channels the first substrate is bonded to the side wall portions; and wherein the first substrate is C-wrapped along longitudinal edges of the core to form C-flaps and the second substrate is placed inwardly of these C-flaps. 2. The absorbent core according to claim 1, wherein the deposition area of the layer of first superabsorbent polymer particles comprises discrete land areas separated by junction areas substantially free of first superabsorbent polymer particles. 3. The absorbent core according to claim 2, wherein the fibrous layer of thermoplastic adhesive material covers the land areas and the junction areas. 4. The absorbent core according to claim 2, wherein the core has a longitudinal axis, and wherein the basis weight of the first superabsorbent polymer particles in the land areas varies to form a profiled distribution of the first superabsorbent polymer particles in the direction of the longitudinal axis of the core. 5. The absorbent core according to claim 1, wherein a length of the one or more channels is at least 20% of a length of the core and a width of the one or more channels is at least 5 mm. 6. The absorbent core according to claim 1, wherein the second absorbent layer comprises one or more channels substantially extending in the longitudinal direction of the core. 7. The absorbent core according to claim 6, wherein the one of more channels of the first and second absorbent layers are at least partially overlapping and the first and second substrates are bonded to each other through these channels. 8. The absorbent core according to claim 1, wherein the first substrate and the second substrate are made of the same or different nonwoven materials. 9. The absorbent core according to claim 8, wherein the first substrate is treated such that it is more hydrophilic than the second substrate. 10. The absorbent core according to claim 1, wherein the first superabsorbent polymer particles and the second superabsorbent polymer particles are made of different materials. 11. The absorbent core according to claim 10, wherein the first superabsorbent polymer particles have a higher Urine Permeability Measurement (UPM) than the second superabsorbent polymer particles, as measured according to the Urine Permeability Measurement Test. 12. The absorbent core according to claim 1, wherein the mixed layer comprises a homogeneous mix of the second superabsorbent polymer particles and the cellulosic fibers, and wherein the mixed layer comprises from 10% to 70% of the second superabsorbent polymer particles by total weight of the mixed layer. 13. The absorbent core according to claim 1, wherein the basis weight of the mixed layer is uniform across its deposition area on the second absorbent layer. 14. The absorbent core according to claim 1, wherein at least one of the first superabsorbent absorbent particles and the mixed layer are deposited in a non-rectangular deposition pattern on their respective substrate. 15. The absorbent core according to claim 1, wherein the deposition area of the layer of first superabsorbent polymer particles is smaller than the deposition area of the mixed layer.
