摘要：The investigation of aquatic and dry land weeds as fibers resources for paper making was carried out. The selected fiber resources of aquatic weeds were water hyacinth (Eicchornia crassipes) and water chestnuts (Eleocharis dulcis),and bladygrass (Imperata cylindrica) as the selected dry land weed. Research was designed as a factorial completely randomized design with two factors. The first factor was fibers origin (Eicchornia crassipes, Imperata cylindrica and Eleocharis dulcis) and the second factor was the fibers pulp slurry concentrations (30%, 50%,and 70% v/v). Results showed that the fibers origin and fibers pulp slurry concentration had significant effect (p<0.05) on the tensile strength,mass density,water absorption,and frictional resistance of paper. The interaction between the fibers origin and fibers pulp slurry concentration had significant effect on tensile strength,frictional resistance,water absorption;but had no significant effect on mass density of paper. The paper that was made of 70% (v/v) of water hyacinth fiber pulp slurry showed the best characteristics with the tensile strength of 3.65 kgf mm-1 ,mass density of 0.87 g cm-3 ,water absorption of 0.235 g cm-2 ,and frictional resistance of 0.028 g cm-2 ..
