三倍体毛白杨化学组分纤维形态及制浆性能的研究

该文对三倍体毛白杨的纤维形态、化学组分进行了观察和测定，发现其纤维平均长度大于其它品种的杨树，纤维的壁腔比也很小，纤维素含量高，木素含量少，是一种较好的造纸原料．对三倍体毛白杨进行硫酸盐法蒸煮，并对其纸浆性能进行检测分析表明，三倍体毛白杨易蒸煮、易漂白，其成浆得率和白度较高，物理强度较好．

Timber Characteristics and Pulp Properties of the Triploid of Populus tomentosa

The results of analysing the timber of the triploid of Populus tomentosa,indicate that the average fiber length of the triploid of Populus tomentosa is 1.09mm, longer than that of other samples tested,and it has bigger ratio of length to width and smaller ratio of cell wall thickness to lumen diameter.It's concluded by using the method of KP pulping that the triploid of Populus tomentosa serve the best from aspects of pulping and paper making and other factors, such as readily cooked and bleached nature, higher brightness and yield and stronger physical intensity.It is further confirmed that triploid of Populus tomentosa is a promising raw material for the pulping and paper making industry.
