Abstract

The invention discloses a preparation method of bamboo pulp, bamboo pulp and fiber, wherein the preparation method includes material preparation, material cutting, cooking and papermaking, and the preparation method also includes grading after the cooking and before the papermaking. , screened out 0.5-3.0mm bamboo fiber for papermaking. The invention ensures the cellulose length distribution ratio by increasing the grading process after cooking and before papermaking, so that the quality of the obtained bamboo pulp is higher, and the quality of the fibers obtained from the obtained bamboo pulp is better.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a preparation method of bamboo pulp, bamboo pulp and fibers. 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 related industries in my country. Conducive to the healthy and stable development of related industries. However, the production of wood and cotton linter in my country is limited due to the constraints of planting area, growth cycle, ecological balance and cost, and the existing wood is mostly imported. Therefore, solving the problem of raw materials has become the top priority of promoting the development of textile raw materials in my country. [000...
