Processing technology of primary pulp natural-color toilet paper

Abstract

The invention discloses a processing technology of primary pulp natural-color toilet paper. The processing technology comprises the following steps: crude wood pulp and crude bamboo pulp are firstly prepared for later use, then are selected according to a mass ratio of 2:1, and are repulped and ground, then paper is formed through suction of a vacuum net cage, and the formed paper is dried, cut and rolled to produce the finished product. The bamboo pulp has high tearing strength and bulk, and is mixed with wood pulp for use, so the tearing strength of the toilet paper can be improved, and theproblem that the existing paper is prone to breaking is solved; the bamboo material and the wood material are separately cooked, so the use rate of raw materials is increased; the bamboo pulp is addedinto the wood pulp, so the cost of the paper is reduced; when the bamboo material is cooked, different cooking solutions are adopted, so the lignin removal rate is increased; and a wet strength agentand a papermaking dispersant are added, so the bulk and wet strength of the toilet paper are improved, and the prepared toilet paper has good softness, good water absorption and uniform color.

Description

technical field [0001] The invention relates to the related field of toilet paper processing, in particular to a processing technology of raw pulp natural color toilet paper. Background technique [0002] At present, almost all toilet paper on the market has been bleached. Most of the bleaching agents used are carcinogenic and mutagenic, which are not beneficial to human health and have a great impact on the water environment. With the enhancement of people's awareness of environmental protection and health, natural toilet paper is produced to meet the needs. At present, pure wood pulp is generally used for production, which makes the production cost high, which is not conducive to long-term use, and the tearing and bulk of the paper are low. Bring many troubles to people using toilet paper. Contents of the invention [0003] The purpose of the present invention is to provide a processing technology of toilet paper with raw pulp and natural color, so as to solve the probl...

Problems solved by technology

[0002] At present, almost all toilet paper on the market is bleached. Most of the bleaching agents used are carcinogenic and mutagenic, which are not good for health and have a great impact on the water environment.

With the enhancement of people's awareness of environmental protection and health, natural toilet paper is produced to meet the needs. At present, pure wood pulp is generally used for production, which makes the production cost relatively high, which is not conducive to long-term use by people, and the tearing degree and bulk of the paper are low. Bring a lot of trouble to people using toilet paper
