| 中文摘要: |
| 为了保留竹子的天然抗菌性，以四川慈竹为原料，利用碱预浸低温硫酸盐法和常规硫酸盐法制备竹浆，对两种工艺条件下的浆料性质进行对比，探讨了碱预浸低温硫酸盐法蒸煮的最佳工艺条件。结果表明，最佳碱预浸条件为：预浸温度120℃，NaOH用量12%，渗透剂用量1.75%，预浸时间30 min；预浸后的蒸煮条件：用碱量（以Na2O计）20%，硫化度18%。碱预浸低温硫酸盐法浆粕中α-纤维素含量能够达到91%以上，且较常规硫酸盐法有更好的抗菌性。 |
| Abstract: |
| Properties of two kinds of bamboo pulps using Neosinocalamus affinis as new material and obtained by alkali-preimpregnation and non-preimpregnation kraft pulping were compared in order to improve the cellulose property of dissolving bamboo pulp and its antibacterial property. The optimum cooking conditions of alkali-preimpregnation kraft pulping were also determined as preimpregnation with 10% NaOH and 1.75% DHQ for 30 min; alkali charge in the following cooking was 20% alkali dosage and sulfidity 18%. Compared with non-preimpregnation kraft pulping, the content of α-celluloses of the pulp produced by the low temperature alkali-preimpregnation kraft pulping increased and reached 91% or higher, which could satisfy the demand of dissolving pulp and had better antibacterial. |
