Manufacturing method of bamboo pulp household paper and household paper

Abstract

Embodiments of the invention provides a manufacturing method of bamboo pulp household paper. The method comprises the following steps: providing pulp with bamboo pulp as a main material, separating and grading the pulp; grinding pulp with long fibers as a main material; mixing pulp mainly comprising fibers having lengths smaller than the lengths of the long fibers and larger than the lengths of short fibers with short fiber pulp and the long fiber pulp respectively so as to form first mixed pulp and second mixed pulp respectively; and manufacturing paper from the first mixed pulp and the second mixed pulp. With the above steps, energy consumption is reduced, and the efficiency of a softening agent and a wet strength agent is improved; and the proportion and distribution of bamboo pulp fibers with different lengths in the first mixed pulp and the second mixed pulp are adjusted, so the bamboo pulp fibers can be mixed more uniformly, and thus, the forming performance of the pulp is improved, the requirement of a crescent-shaped paper machine is met, and paper forming performance is further improved. The invention further provides the household paper manufactured by using the manufacturing method of the bamboo pulp household paper.

Description

technical field [0001] The invention relates to a method for making household paper, in particular to a method for making household paper by using bamboo pulp fibers. Background technique [0002] Household paper, such as toilet paper, napkin paper, kitchen paper, etc., is an indispensable daily necessities for people now. Usually, household paper on the market is made of wood pulp, and most of them are combined with softwood pulp and hardwood pulp at the same time. This is because the fiber length of softwood is longer (2-4mm), which can Provide sufficient strength for paper, while hardwood fibers are shorter (less than 1mm), which can make paper have better surface touch and softness, and meet the requirements of different products through different ratios of the two. [0003] However, my country's wood resources are scarce, especially coniferous wood pulp usually needs to be imported, and my country's bamboo resources are abundant, so there is a huge market demand for us...

Problems solved by technology

[0003] However, my country's wood resources are scarce, especially coniferous wood pulp usually needs to be imported, and my country's bamboo resources are abundant, so there is a huge market demand for using bamboo fiber to make tissue paper. The following problems, because the bamboo fiber is slender, the average length of the fiber is about 2.0mm, which is just between the length of the hardwood and the coniferous wood fiber, and the width is generally 15-18μm, the wall thickness is small, the density is high, and the fiber is relatively stiff , fiber cells account for about 50%-60% of the total cell content, so that when the bamboo fiber usage exceeds 85%, on the one hand, it will cause poor pulp formation, and the paper is prone to problems such as dead lines and spots, especially in new bamboo fiber. In moon-shaped paper machines, due to the high speed and strong turbulence in the head box, the above problems are more likely to occur if no or less dispersants are used. On the other hand, the paper produced is stiff and rough, which cannot meet the needs of consumers.
