A preparation method of a fiber is provided. In the preparation method of the fiber, a polymer is dissolved in a mixing solution of an ionic liquid and a salt to form a spinning viscose, wherein the salt includes KCl, KBr, KOAc, NaBr, ZnCl2 or a combination thereof. Afterwards, the spinning viscose is used as a material to perform a spinning process so as to form a fiber. |
