The invention discloses a manufacturing method for a strong-acid ion exchange fiber. The manufacturing method comprises the following steps of: preparing a grafting liquid, carrying out grafting reaction on the grafting liquid to obtain a grafted fiber after pretreating raw materials, carrying out sulfonation reaction after washing, drying and carrying out thermal treatment on the grafted fiber, and finally forming the strong-acid ion exchange fiber. The manufacturing method provided by the invention has the advantages that the raw materials are easily available, the grafting rate is high, and the generated ion exchange fiber is controllable in diameter and has high exchange capacity and good combination property; and the large-scale industrial production of the generated strong-acid ion exchange fiber can be easily realized.
