| Abstract | In this study, 6-year-old hybrid tulip(L. Chinese xL. tulipifera)wood was used as raw material for investigation on the wood density, fiber morphology, and Kraft pulping properties. Compared with normal hardwood, hybrid tulip has moderate wood density (434 kg/m³), bigger length (1.3mm), diameter (24μm)and coarseness (10.6 mg/100m). Under the optimal cooking conditions of AA 22% (as NaOH), Sulfidity 30%(as NaOH), H-factor 850 (cooking at 163-164°C for 75 min), pulping properties with screened yield about 51%, Kappa number around 18, viscosity more than 1000 ml/g, and residual AA about 5 g/lcan be achieved. AA charge and H-factor are very selective parameters for Kraft pulping of hybrid tulip,while sulfidity also plays important role onscreened yield and viscosity. |
