Preparation method of bamboo pulp, bamboo pulp and fibers

The invention discloses a preparation method of bamboo pulp, the bamboo pulp and fibers. The preparation method comprises material preparation, material cutting, cooking and papermaking, the preparation method further comprises grading after cooking and before papermaking, and in the grading process, the bamboo fibers of 0.5-3.0 mm are selected out for papermaking. According to the method, the grading process is added after cooking and before papermaking so that the length distribution proportion of cellulose is guaranteed, the quality of the prepared bamboo pulp is higher, and the quality offibers prepared from the bamboo pulp is better. 本发明公开了一种竹浆粕的制备方法、竹浆粕及纤维，其中，制备方法包括备料、切料、蒸煮、抄造，制备方法还包括在蒸煮后和抄造前进行的分级，分级过程中，筛选出0.5-3.0mm的竹纤维进行抄造。本发明通过在蒸煮后和抄造前增加分级过程，保证了纤维素长度分布比例，使制得的竹浆粕品质更高，所得竹浆粕制得的纤维质量更佳。
