Title:
WOUND-COVERING MATERIAL AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/006159
Kind Code:
A1
Abstract:
The present invention relates to a wound-covering material having at least a hydrogel, the hydrogel containing fine fibrous cellulose having an ionic substituent. The present invention also relates to a wound-covering material production method which is a method for producing the wound-covering material and comprises the step of preparing a hydrogel using a mixture of a hydrophilic polymer and fine fibrous cellulose having an ionic substituent. Thereby, provided are: a wound-covering material having excellent water retention properties and strength and having excellent attachability to and detachability from a living body; and a production method therefor.
