title: Environmental friendly alkaline sulfite anthra quinone-methonal (ASAM) pulping with Rumex crispus plant extract of woody materials.
abstract: ASAM with Rumex crispus extract organosolv pulping was developed by using 1,5-dihydroxy-3-methoxy-7-methyl-anthraquinone from Rumex crispus root, instead of anthraquinone. ASAM was also produced as a control pulping. Both pulps were made by handsheets from fast growing P. deltoides clone (Samsun p. clone), Robinia pseudoacacia L. and Pinus pinaster grown in Turkey for wood fibrous raw materials. The mechanical consisting tensile, bursting and tear values and optical values of ASAM handsheets yellowness, brightness and whiteness were compared to ASAM with Rumex crispus L. extracted. It is concluded that ASAM with Rumex crispus extract pulping suits well in the manufacturing of special papers.
