Description

technical field

[0001] The present invention relates to an absorbent sheet suitable for use in sanitary napkins, sanitary pads, disposable hand towels, medical pads, nursing pads, liquid absorbent sheets, kitchen paper towels, household cleaning towels, pet towel pads, etc. A method of making the sheet, and an absorbent article made from it. Background technique

[0002] Many methods are known for immobilizing superabsorbent polymers in absorbent structures to obtain absorbent sheets. For example, USP3070095 discloses a method such as Figure 24 As shown, the method includes placing superabsorbent polymer 116 on fabric 110, placing another fabric 111 on top of it, and pressing the superabsorbent polymer into the fabric with a roller. However, according to this method, the superabsorbent polymer is fixed only in the layer between two fabric layers, so this method cannot be used to fix a large amount of superabsorbent polymer. if Figure 24 If the absorbent sheet shown is us...
