Problems solved by technology

However, as a water-soluble cationic polymer, the quaternary ammonium salt antibacterial agent is mainly combined with the pulp fiber through adsorption in the pulp, and the binding force is low, so a large amount of the quaternary ammonium salt antibacterial agent will be lost during the dehydration process. The content of antibacterial agent in antibacterial paper is seriously reduced, which not only causes a serious waste of antibacterial agent, but also leads to an increase in the production cost of antibacterial paper

Abstract

The invention relates to a production process of antibacterial paper. The production process comprises the following steps: providing paper pulp; adding anion nano-microcrystalline cellulose and an quaternary ammonium salt into the paper pulp to prepare mixed pulp; and producing the paper with the mixed pulp. The invention further relates to the antibacterial paper produced by utilizing the process. Compared with the prior art, the production process of the antibacterial paper can ensure that an antibacterial agent added into the paper pulp has good retention rate, and the antibacterial paper produced according to the production process of the antibacterial paper has good paper strength and antibacterial capability.

Description

technical field [0001] The invention relates to a production process of antibacterial paper and antibacterial paper. Background technique [0002] With the rapid development of the household paper industry and the increasingly obvious consumer demand for high-end household paper, ordinary household paper can no longer meet the needs of consumers. Therefore, various functional household paper Products also appear on the market thereupon, and one of them is exactly the product with antibacterial effect. [0003] As a good antibacterial agent, quaternary ammonium salt antibacterial agent is often added to the wet end of papermaking to produce paper with antibacterial effect. However, as a water-soluble cationic polymer, the quaternary ammonium salt antibacterial agent is mainly combined with the pulp fiber through adsorption in the pulp, and the binding force is low, so a large amount of the quaternary ammonium salt antibacterial agent will be lost during the dehydration proce...
