Abstract
- To use the African tulip tree (Spathodea campanulata) as raw material for chemical pulp-ing, soda and soda-AQ pulping was investigated. In chemical compositional analysis, lignin contents of African tulip (33.1%) was higher than other hardwood such as Yellow poplar (17.5%), Acacia (27.1%), or Eucalyptus (24.2%). Soda or soda-AQ pulping with African tulip tree resulted in yield at 43.4-44.8% with 29.5-34.5 Kappa number, pulping condition with 20-22% active alkali. Kappa number of African tulip tree pulp was quite higher than other tropical hardwood (Eucalyptus or Accacia) with less yield due to higher lignin content in wood. Fiber length and width of pulp from African tulip tree was similar to Accacia pulp and shorter than eucalyptus pulp.Keywords: African tulip, soda-AQ pulp, soda pulp, Kappa number http://dx.doi.org/10.7584/ktappi.2015.47.5.085Journal of Korea TAPPIVol. 47.
