摘　　要：对卡伯值为11.4的深度脱木素硫酸盐竹浆进行D0(EOP)D1的ECF短序漂白。结果表明,在D0和D1的有效氯用量分别为17kg·t-1和11kg·t-1,H2O2用量为5kg·t-1时,可得到白度为80.1%ISO的漂白竹浆;将D0和D1的有效氯用量分别增至22kg·t-1和15kg·t-1,H2O2用量仍为5kg·t-1时,可得到白度为85.9%ISO的漂白竹浆。两种漂白浆都具有很好的强度性能,相同打浆度下,白度为80.1%ISO的漂白竹浆其各项强度性能略优于白度为85.9%ISO的漂白竹浆;从打浆转数与打浆度的关系上来看,在达到相同打浆度时白度为80.1%ISO的漂白竹浆需要的打浆转数略少。ECF short sequence D0（EOP）D1 bleaching was used to bleach kraft bamboo pulp with 11.4 Kappa number. The results showed that the bleached pulp with brightness of 80.1%ISO was obtained when the active chlorine charge in D0 and D1 were 17kg·t^-1 and 1lkg·t^-1, respectively; and bleached pulp with 85.9%ISO was also obtained with 22kg·t^-1 in Do and 15kg·t^-1in D1, The property testing of the sheets which made from the bleached bamboo pulps indicated that both the bleached pulps had very good strength properties. The bleached pulp with 80.1%ISO had slightly better strength properties than the brighter one, and was also slight easier to beat to the same beating degree.
