The invention belongs to the technical field of art crafts, and particularly relates to a preparation method of high-strength and high-water absorption craft woven paper. The preparation method comprises the following specific steps: (1) weighing raw materials, (2) mixing cotton shells with soybean straw, performing crushing, performing steam treatment, freezing treatment and steam treatment, andconducting cooling to room temperature so as to obtain a straw-shell material, (3) soaking corn bran in an acetic acid aqueous solution, performing cold storage treatment, mixing the obtained corn bran with gumbo leaf fermentation broth, performing crushing and pulping, adding the straw-shell material, and performing even mixing so as to obtain a pulp material, (4) adding algal polysaccharides, Sargassum fusiforme polysaccharides, modified potato starch and modified lotus root starch to the pulp material, performing heating with gentle fire, adding aminomethylbenzoic acid, sodium sulfamate andnano zinc oxide, performing homogenizing treatment, and performing paper making and drying. The water absorption performance of the paper can be ensured effectively, the paper is flexible and elastic, and has high structural stability and resistance to cracking and tearing, and smooth printing and writing can also be maintained effectively, so that the efficiency and performance of application ofthe craft woven paper are improved greatly.
