文摘内容 The potential use of Samaar Morr (JUNCUS ACUTUS) plant as fibrous material in papermaking was evaluated in this study. The chemical analysis and fibre charactersitcs of this plant were determinedfor better understanding its behaviour in papermaking. Samaar morr stalks were subjected to sulfur-free three-stage (peroxyformic acid, formic acid, peroxyformic acid) Milox process. Some conventional pulping experiments such as soda, soda-anthraquinon (S-AQ), kraft and kraft-AQ pulping in addition to two- and one-stage peroxyformic acid pulping were also carried out for comparison with the three-stage peroxyformic acid pulping method. It was found that the pulping with Milox process produces pulp with good properties compared to the pulp produced from the other methods. The physical and optical properties of different pulps were also examined. The behaviour of Milox samaar morr pulp towards bleaching withalkaline hydrogen peroxide has been investigated in presence and absence of formic acid. The results showed that the final brightness about 81.5% ISO could be achieved after 3% peroxide in two bleaching steps with formic acid treatment between the two steps。
