Document Type and Number:
WIPO Patent Application WO/2015/182438
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a fine-fiber-containing sheet in which yellowing is suppressed. The present invention also addresses the problem of providing an effective method for dissociating introduced substituents, and a composite sheet obtained by layering an organic layer and/or an inorganic layer in the obtained sheet. Provided is a method for manufacturing a fine-fiber-containing sheet, the method having: (a) a step for causing substituents that have electrostatic and/or steric functionality to be introduced into a fiber raw material, and obtaining a substituent-introduced fiber; (b) a step for mechanically processing the substituent-introduced fiber obtained in step (a), and obtaining a substituent-introduced fine fiber; (c) a step for preparing a sheet from the substituent-introduced fine fiber obtained in step (b); and (d) a step for dissociating at least some of the introduced substituents of the sheet obtained in step (c).
