The average closest distance between two neighboring crosslinkers (R XL ) in a water-absorbing polymer particle for a specific X-load of the water-absorbing polymer particle is calculated via the formula below: Rxl = 1 rho_dry + x_L rho_liq N A ⋅ ∑ i w − xl i Mr_CXL i 1 3
with x_L being the amount of liquid absorbed in the water-absorbing polymer particle in g liq /g water-absorbing polymer particle ,
rho_liq being the density at room temperature of the fluid that swells the water-absorbing polymer particle (generally saline of 0.9%w NaCl) in g/cm 3 ,
rho_dry being the true density of the dry water-absorbing polymer particle in g/cm 3 ,
Mr_CXL being the molar mass of the crosslinkers in g/mol,
w_xl being the weight ratio of crosslinkers in dry water-absorbing polymer particle,

摘要： An absorbent core for use in an absorbent article is provided and comprises a core wrap enclosing an absorbent material, the absorbent material comprising superabsorbent polymer particles. The core wrap comprises a top side and a bottom side. The absorbent core comprises one or more area(s) substantially free of absorbent material through which the top side of the core wrap is attached to the bottom side of the core wrap (i.e. core wrap bond(s)), so that when the absorbent material swells, the core wrap forms one or more channel(s) along the area(s) substantially free of absorbent material. The superabsorbent polymer particles have a value of Effective Capacity (EFFC) of at least 27 g/g. The Effective Capacity (EFFC) is calculated via the formula below: EFFC = (CRC+AAP)/2. The Centrifuge Retention Capacity (CRC) is measured according to the Centrifuge Retention Capacity (CRC) test method and the Absorption Against Pressure (AAP) is measured according to the Absorption Against Pressure (AAP) test method. The superabsorbent polymer particles have a bulk density of at least 0.5 g/ml according to the Bulk Density Test Method.

摘要： Agglomerated superabsorbent polymer particles is provided and obtained by a method comprising the steps of:
a) providing precursor superabsorbent polymer particles having a first mass average particle size 1 mAvPS, a first particle diameter " 1 D10" of not less than 30 µm and a first particle diameter " 1 D90",
b) mixing the precursor superabsorbent polymer particles with a solution comprising polymerizable monomers and/or oligomers, or crosslinkable polymers, and
c) polymerizing the mixed solution if the solution comprises polymerizable monomers and/or oligomers or crosslinking the mixed solution if the solution comprises crosslinkable polymers. The agglomerated superabsorbent polymer particles have a second particle diameter " 2 D10" and a second particle diameter " 2 D90". The size ratio between the second particle diameter " 2 D90" and the first particle diameter " 1 D10" is determined by the following equation: 7 SizeRatio = D 90 2 D 10 1 21
