【摘要】 在对引种四川桤木纤维形态和化学组分分析的基础上，通过对浸渍温度、浸渍时间、磨浆浓度和磨浆间隙等因素进行正交试验，提出了引种四川桤木CTMP最佳制浆工艺。将漂白后的浆料取代马尾松GP和TMP并与其它浆种配抄成新闻纸。试验结果表明，四川桤木CTMP法制得的成浆适宜配抄新闻纸，成纸的各项性能指标均达到新闻纸优等品国家标准。更多还原

【Abstract】 The optimum CTMP pulping process of alnus cremastogyne wood was studied on the factors such as impregnating temperature and time， refining consistency and clearance of refiner， based on the fiber morphology and chemical compositions． As the substitution for GP and TMP of Massion’s pine， the bleached alder CTMP could be used as newsprint furnish with other pulps． Laboratory and pilot trials indicated that high quality newsprint can be produced from furnish containing up to 50％ alnus cremastogyne CTMP．更多还原
