摘　　要：以稻草为原料,采用一段漂和碱处理联合漂剂漂白两种方法对对甲苯磺酸纸浆进行漂白性能的研究,分析漂剂种类、漂白时间等因素对纸浆白度、得率以及成纸物理强度的影响。结果显示,一段漂在改变漂剂浓度以及延长漂白时间条件下,漂白效果均未达到理想值,而碱处理联合次氯酸钠后的白度可达到82.7%,效果良好。The bleachability of p-toluenesulfonic acid pulp were studied by means of one stage bleaching and alkali treatment combined with bleaching agent. The effects of bleaching agent type, bleaching time and other factors on the whiteness, yield and physical strength of the pulp were analyzed. The results showed that the bleaching effect did not reach the ideal value under the condition of changing the concentration of bleaching agent and prolonging the bleaching time, but the whitness of alkali treatment combined with sodium hypochlorite could reach 82.7%, and the effect was good.
