摘　　要：研究了白腐菌对竹片进行生物预处理再进行化学机械法制浆的工艺和机理。生物预处理使竹子化机浆具有较好的物理强度。通过纤维特性分析,化机浆的纤维长度在生物预处理后增加,细小纤维含量降低。电子显微镜观测用来鉴定白腐菌预处理前后竹浆纤维表面形态和内部结构的变化,纤维表面和内部细胞壁结构的变化有助于纸张强度的提高。This paper studied on the technology and mechanisms of bamboo chemimechanical pulping with white-rot fungi pretreatment. Comparing to the control pulp, fungal pretreatment resulted in better pulp strength properties. According to pulp fiber quality analysis, fungal pretreatment increased the fiber length and reduced the fines contents. Electron microscopes were also used to identify the chips cell wall and pulp morphology changes brought by fungal pretreatment. Changes in fiber surface and internal cell wall structure contributed to the strength properties improvement.
