Abstract

A shaped chitin body prepared by treating a shaped body of chitin with an alkali solution, such that within a dilute aqueous solution of acetic acid, the volume of said shaped chitin body will increase by a factor of at least about 10 while substantially retaining its shape. This shaped chitin body has versatile capabilities comparable to those of chitosan. A nonwoven fabric made of a fibrous chitin body is particularly effective as a wound dressing.
