Abstract: The invention discloses a preparation method of a double-net hydrogel fiber and a product thereof. The preparation method mainly includes following steps: (1) preparation of a spinning raw solution: dissolving one or more water-soluble natural polysaccharides and a water-soluble acrylamide polymer in water with stirring uniformly, and performing filtration and defoaming to obtain a mixed spinning raw solution containing the natural polysaccharides and the acrylamide polymer; (2) preparation of a water-containing primary gel fiber: performing wet spinning, or dry-wet spinning or gel spinning to the mixed spinning raw solution prepared in the step (1), performing a spinning process at a preset speed, mixing the mixed spinning raw solution with a coagulating bath, to obtain the water-containing primary gel fiber; and (3) radiation crosslinking: drafting the primary gel fiber into an ionizing radiation apparatus and performing the radiation crosslinking to the primary gel fiber prepared in the step (2), and performing a subsequent drafting operation, a thermal-moulding operation, a winding-up operation and a fiber-cutting operation to obtain the double-net hydrogel fiber.
