Abstract
This invention provides a method of producing chitosan non-woven fabrics and an apparatus thereof. At first, a chitosan acidic solution is extruded to form a chitosan fibrous stream. Then, a solidifying agent is ejected to form a solidifying agent stream. The solidifying agent stream and the chitosan fibrous stream are combined to form a pre-solidified chitosan fiber. Then, high-pressure air is ejected on the pre-solidified chitosan fiber to stretch the pre-solidified chitosan fiber. Finally, the chitosan fibers are collected to form chitosan non-woven fabrics.
