[0017] The preparation method of household paper of the present invention, it comprises the steps:
[0018] (1) Copying and preparing household paper.
[0019] The pulp used in making the household paper of the present invention is selected from kraft chemical pulp (coniferous tree, broad-leaved tree, bleached or unbleached kraft pulp, etc.), mechanical pulp (groundwood pulp, thermomechanical pulp, chemical thermomechanical pulp, etc.) ), one or more of deinked pulp (old newspaper, old magazine paper, etc.). Kraft chemical pulp is preferably used in the present invention.
[0020] The method of making household paper adopts all conventional steps, basically including but not limited to the following steps: pulping→loose pulp and refining→online forming→pressing and drying→creping to make tissue paper.
[0021] In the preparation process of the tissue paper of the present invention, the paper sheet does not need to increase or decrease the moisture content during creping trea...
Embodiment 1
[0027] Prepare pulp (quality of hardwood fiber: quality of softwood fiber = 3:1), carry out pulping and refining, form on the net, press and dry to obtain a paper web with a moisture content of 4%, then crepe it, and then pass it through coating Uniformly apply 7% of the base paper mass chemical medicine to the two outer surfaces of the paper web by means of cloth (the specific formula is: 43% royal jelly hydrolyzate, 12% N,N,N,-trimethylcarboxymethyl chitosan Sugar quaternary ammonium salt, 5% antibacterial agent (honeysuckle), 0.1% essence, 39.99% distilled water), wrap the obtained paper roll with a film and seal it well, let the chemical medicine balance in the paper for 3-7 days.
Embodiment 2
[0029] Prepare pulp (quality of hardwood fiber: quality of softwood fiber = 3:1), carry out pulping and refining, form on the net, press and dry to obtain a paper web with a moisture content of 5%, and then perform creping treatment, and then pass coating Uniformly apply 16% of base paper mass chemicals (specific formula: 25% carboxymethyl trehalose, 12% nostoc polysaccharide, 10% ethylhexyl methoxycinnamate) to the two outer surfaces of the paper web by means of cloth ester, 10% stearyl ether, 2% antibacterial agent (tea tree essential oil), 0.6% essence, 40.4% distilled water), wrap the obtained paper roll with a film and seal it well, let the chemical medicine balance in the paper for 3-7 days That's it.

Abstract
The invention provides household paper. A chemical drug is applied to at least one surface of the household paper. The application volume of the chemical drug takes up 5%-30% of the mass of the household paper. The chemical drug refers to a substance which comprises at least one of the hydrophilic groups of an amino group, a hydroxyl group, a carboxyl group, an ester group, an ether group, an amide group and a quaternary ammonium group, and the volatility of the substance is lower than water. The invention further provides a preparation method of the household paper. The chemical drug with hydrophilia and low volatility is applied to the surfaces of the household paper; after a period of balance, the chemical drug will be absorbed in fibers of the household paper stably due to the low volatility of the chemical drug; due to the high hydrophilia of the chemical drug, the chemical drug will absorb moisture in the air and lock the moisture in the fibers of the household paper, and the overall hand feel of the household paper is extremely soft.
Description
technical field [0001] The invention relates to a living paper and a preparation method thereof. Background technique [0002] At present, in the paper industry, there are many ways to improve the softness of paper, one of which is to increase the softness of paper by increasing the moisture content of paper. [0003] Increasing the moisture content of paper can mainly increase the moisture content of paper in two stages of paper production, one is in the drying stage of the paper machine, and the other is in the back-end processing stage of paper. If the paper moisture is increased during the drying stage of the paper machine, the paper sheet is first dried on the drying cylinder to the specified moisture content, and then the surface of the drying cylinder is wrinkled by a scraper to make the paper sheet leave the drying cylinder. The remaining moisture in the paper will form a protective film on the surface of the paper fiber. When the scraper acts on the surface of the ...
