Abstract

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.

Description

technical field [0001] The invention belongs to the textile field, and in particular relates to a preparation method of bamboo pulp, bamboo pulp and fiber. Background technique [0002] my country is the world's largest producer of textiles and raw materials. In recent years, due to the development of urbanization, the improvement of people's living standards, the change of consumption concepts and the strengthening of health and environmental protection awareness, there are great risks in the sustainable development of my country's related industries. Conducive to the healthy and stable development of related industries. However, the production of wood and cotton linters in my country is limited due to factors such as planting area, growth cycle, ecological balance and cost, and most of the existing wood is imported. Therefore, solving the problem of raw materials has become the most important thing to promote the development of my country's textile raw materials. [0003]...
