摘　　要：本文研究了硫酸盐毛竹浆的二甲基二氧环乙烷漂白，并提出了相应的全无氯漂白流程，研究结果表明，硫酸盐毛竹浆ＡＥＰ段漂白与传统的ＣＥＨ段漂白相比较，有较高的脱木素率和白度，再经过一段过氧化氢漂白，白度可达７８％（ＳＢＤ）．In this paper, the technique of dimethyldioxirane bleaching Phyllostachys Pubescens kraft pulp is studied and its relevant totally-chlorine-free bleaching process is put forward.The research results show that compared with CEH bleaching, AEP bleaching of Phyllostachys pubescens kraft pulp possesses high delinification rate and brightness.Furthermore, the brightness of phyllostachys pubescens kraft pulp can be improved to 78%(SBD) by AEPP.
