Title:
MANUFACTURING METHOD OF WATER ABSORPTIVE STRUCTURE
Document Type and Number:
Japanese Patent JP2021080608
Kind Code:
A
Abstract:
To provide a manufacturing method of a water absorptive structure with small thickness under reduced dry load.SOLUTION: A manufacturing method of a water absorptive structure involving a fibrous material and a water absorptive polymer is provided. Firstly, a slurry involving a fibrous material and a water absorptive polymer dispersed in a liquid dispersion medium is prepared. Then, the liquid dispersion medium is removed from the slurry to make a sheet body involving the fibrous material and the water absorptive polymer. This manufacturing method employs a fibrous material having a freeness of 300 mL or more. Moreover, this manufacturing method employs a liquid dispersion medium having a swelling degree of the water absorptive polymer of 2.5-fold or under when soaked in the liquid dispersion medium.SELECTED DRAWING: None
