Title:
MOISTURE-CONTROLLABLE SHEET
Document Type and Number:
Japanese Patent JP2004068188
Kind Code:
A
Abstract:
To obtain a moisture-controllable sheet which is obtained by dispersing porous powder having specific pore diameters into cellulose fibers, has basis weight at 23°C at 50% relative humidity of a fixed range and is made to specify that the ratio of absorbed and released moisture amounts in a middle humidity range to the whole absorbed and released moisture amounts is extremely raised in comparison with a conventional moisture-controllable sheet.
The moisture controllable sheet is obtained by dispersing the porous powder having 2.5-5.0 nm average pore diameter into the cellulose fibers. The porous powder contains 40-90 mass % solid content and the cellulose fibers contain 10-60 mass % content.
