SUPERABSORBENT POLYMERS FOR HIGHLY FILLED AND FIBER-FREE HYGIENE PRODUCTS

摘要

The invention relates to a particulate, absorbent polymer material comprising at least one of the following properties: i) a maximum APCi x 10 sec-value of >=1.6 for at least one number i selected from the group of the whole numbers from 2 to 12 (=APCmax); ii) a value for the sum of all APCi × 10 sec-values of >= 12 for all numbers i from the group of whole numbers from 2 to 12 (=APCsum); wherein the APCi x 10 sec-value is defined as follows: APCi × 10 sec=QIi × 10 sec-value2 ×PIi × 10 sec-value, wherein - the QIi x 10 sec-value value is the value of the source index determined according to the test method described herein i x 10 seconds after adding the 0.9 wt % of NaCl solution and - the PIi x 10 sec-value the value of the permeability index according to the test method described herein i x 10 seconds after adding the 0.9 wt % of NaCl solution. The invention also relates to an absorbent core comprising such a particulate absorbent material, to a hygiene product, to a method for producing an absorbent core and to an absorbent core that can be obtained by said method.
