My TAPPI Story: Naomi Gehling
This study was undertaken to determine the effects of anthraquinone on the yield and quality of Populus euphratica oliv. and Eucalyptus cammaldulensis Dehn. Soda pulping. The addition of 0.1% anthraquinone to wood chips in soda pulping increased the pulp yield of Populus euphratica from 43% to 46.6% and pulp yield of Eucalyptus cammaldulensis from 45% to 48.5%. Breaking length increased significantly after that addition from (6210m) to (6913m) for Populus euphratica pulp and from (7250m) to (7642m) for Eucalyptus cammaldulensis pulp. The AQ addition significantly enhanced Kappa number reduction of Populus euphratica from 25 to 20 and for Eucalyptus cammaldulensis from 40 to 36. Anthraquinone addition increased significantly tear factor of Populus euphratica from 58 to 72 and tear factor of Eucalyptus cammaldulensis from 80 to 86. The addition of anthraquinone did not affect burst factor.
