Manufacturing method of bamboo pulp household paper and household paper

Abstract

The embodiment of the invention provides a papermaking method of bamboo pulp household paper. The papermaking method comprises the following steps: taking bamboo pulp as main pulp, dividing a slurry into a slurry A and a slurry B; separating the slurry A and the slurry B; mixing the separated slurries to form a first mixed slurry and a second mixed slurry; grinding the second mixed pulp; adoptingthe first mixed pulp and the ground second mixed pulp for papermaking in a papermaking machine; wherein the papermaking machine is a crescent-shaped papermaking machine; slurry distribution and grading treatment are adopted, so that the distribution and proportion of fibers with different lengths in the bamboo pulp can be adjusted; on one hand, energy consumption can be reduced, and the efficiencyof softeners and wet strength agents is improved; on the other hand, after distribution and proportion of fibers with different lengths in the bamboo pulp are adjusted, the pulp has better forming performance, the papermaking requirement of a crescent-shaped papermaking machine is met, meanwhile, the paper forming performance of paper is improved, and the invention further provides the householdpaper manufactured through the bamboo pulp household paper papermaking method.

Description

technical field [0001] The invention relates to a method for making household paper by utilizing bamboo pulp fibers and the household paper. 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 using bamboo fiber to make t...

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.
