Abstract: Jute/soybean dregs/starch composites were prepared by wet lamination method with jute fiber as a reinforcement phase and soybean dregs/starch solution modified by NaOH as a matrix phase.The effects of the mass ratio of soybean dregs/starch, mass fraction of jute, hot-pressing temperature, hot-pressing strength, and hot-pressing time on the tensile properties and hydrophilicity of the composite sheets were studied by orthogonal experiment design. The results showed that when the mass ratio of soybean dregs/starch was 3：1, mass fraction of jute was 20%, compression intensity was 6 MPa, hot-pressing temperature was 80°C, and hot pressing time was 2 min, the tensile fracture strength of the composite sheet was the best. The prepared composite sheets have good hydrophilicity, but poor water resistance.
