Abstract:Through cultivation of white rot fungi the flaky fungal hyphae was obtained， the fungal hyphae was separated with a high speed homogenizer after alkali treatment then mixed with the pulp to prepared a sheet. The effect of fungal fiber on the properties ofthe sheet was studied. The physical strength of the paper obtained by mixing the fungal fiber with the vegetable fiber increased significantly， and the physical strength of the paper increased the most when the fungal fiber was added 0.48 g （oven dried） based on 2 g oven dried pulp. Tensile index of the paper increased by 79.6% percent， bursting index increased by 148.9%， whiteness decreased slightly， and the paper showed a certain hydrophobicity mainly due to the fungal fiber which contains hydrophobic protein and played a bridging and filling role between plant fibers.
