<p>A cross-linked fiber is provided by cross-linking a fiber made of polyglutamic acid sodium of molecular weight of 200,000 or more and a polymer cross-linking agent. The polymer cross-linking agent is preferably a polymer having an oxazoline group or a polymer having an epoxy group. The cross-linked fiber is manufactured by: spinning threads from a solution in which the material is mixed by an electrostatic spinning to form a fiber and a fiber assembly; and heating the fiber and the fiber assembly to form the cross-linked fiber.</p> |
