Abstract

PURPOSE: Chitosan resulting from hydrolysis of chitin that is widely distributed in crustaceans or its salt is dissolved in water and the solution is dry-wet formed using an aqueous solution containing a basic substance to produce a novel type of formed products such as fiber.
CONSTITUTION: Chitin that is widely distributed in outer shells of crustaceans such as lobster or crab is hydrolyzed with a conc. alkali to form chitosan composed of 2-amino-2-deoxy-D-glucose. Then, the product in flakes is previously suspended in water and mixed throughly. Then, an aqueous acetic acid is added to dissolve it into a dope. The dope is extruded, e.g., through a spinning nozzle into a coagulation bath of an aqueous solution of a basic substance such as sodium hydroxide according to a wet or dry method to give the objective formed product.
