Description
Technical Field
The invention relates to a production process of paper, in particular to a production method of toilet wiping paper with high strength and easy dispersion.
Background
Along with the increasing living standard, the requirement of the public on the living quality is higher and higher, the use of the closestool is basically popularized, the closestool is always a serious disaster area of home sanitation, and the daily cleaning of the closestool is always puzzled to people. Many people do not want to make the toilet sanitary because the toilet is dirty, the routine cleaning of the toilet is necessary, but it is impossible to clean the toilet completely after each use, and the toilet seat inevitably has dirty and even bacteria residue after each use, and the toilet seat is in direct contact with the skin, so the prior art generally has two forms, namely, a disposable seat cover sanitary paper is used, and the disposable seat cover sanitary paper is laid on the toilet seat cover when each use is performed, but is inconvenient to use and easy to move, and the seat cover paper is mainly used for protecting the skin of people from contacting the surface of the toilet seat, generally consists of soft and smooth (glass-like) paper, is sometimes impregnated with chemicals (such as antibacterial compounds), and can not be flushed away directly through the toilet after use; another way is to wipe the toilet seat before each use, with the wipe helping to remove dirt and bacteria from the seat for a safe use.
However, in the prior art, there are few toilet special wiping papers, but personal hygiene papers such as facial tissues, toilet tissues, napkins, hand towels and the like are directly used for wiping, and the papers are generally not strong enough, large in dosage and easy to damage in the wiping process.
Chinese patent ZL201310165061.9 discloses a process for preparing paper, which comprises the following steps: providing softwood pulp and hardwood pulp, wherein the absolute dry mass ratio of the hardwood pulp to the softwood pulp is between 1 and 4, and defibering the softwood pulp and the hardwood pulp respectively; adding a softening agent into the defibered hardwood pulp; mixing hardwood pulp added with a softening agent with fluffed softwood pulp to obtain mixed pulp; and manufacturing the mixed pulp into paper. The process utilizes the different fiber forms of the softwood fiber (long fiber) and the hardwood fiber (short fiber), and can improve the use efficiency of the softening agent, reduce the use amount of the softening agent and reduce the residual amount of the softening agent in a white water system by adjusting the proportion of the two fibers, but the strength of the paper manufactured by the process is lower.
At present, in the paper making process, in order to improve the wet strength of the household paper, polyvinyl alcohol is added into the pulp to be evaluated as a wet strength agent. The pulp for making the household paper is usually a mixture of long fibers and short fibers, namely the pulp is mixed pulp of softwood pulp and hardwood pulp. However, the retention of polyvinyl alcohol is not high when the wet strength agent is added directly to the mixed pulp, resulting in a less than obvious effect of increasing the wet strength of the finished paper. Chinese patent CN201610699969.1 discloses an efficient papermaking process, wherein the wet strength of the paper prepared by the method is higher than that of the paper prepared by the traditional method (polyvinyl alcohol is directly added into mixed pulp of softwood and hardwood) under the condition that the same amount of wet strength agent is added into the same pulp, and the wet strength can be relatively higher by 0.01-8%. Although the paper making process can reduce the use amount of the wet strength agent and improve the use efficiency of the wet strength agent, the wet strength agent has adverse effect on the dispersibility, and the process improves the strength of the paper but loses the dispersibility of the paper, so that the requirements of the strength and the dispersibility are difficult to meet at the same time.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a method for producing high-strength and easily-dispersible toilet wiping paper.
The purpose of the invention can be realized by the following technical scheme: a production method of high-strength easy-to-disperse toilet wiping paper comprises the following steps:
(1) respectively putting softwood pulp (preferably North American softwood pulp) and hardwood pulp (preferably Brazilian hardwood pulp) into a long fiber pulper and a short fiber pulper, adding CMC (carboxyl methyl cellulose) on pulp boards, respectively crushing after adding water, and respectively pumping into a pulp pond before long fiber beating and a pulp pond before short fiber beating;
(2) adding water into softwood pulp from a pulp tank before long fiber beating to adjust the concentration to 4.0-5.0 wt%, pulping by a pulping machine, cutting fibers, devillicating and brooming, and then feeding into a pulp tank after long fiber beating;
(3) adding water into the hardwood pulp from the pulp tank before short fiber beating to adjust the concentration to 4.0-5.0 wt%, fluffing by a fluffer, fluffing the fiber, and then feeding the fiber into the pulp tank after short fiber beating;
(4) pumping the softwood pulp into a mixed pulp tank according to the proportion of 70-80 wt% of softwood pulp and 20-30 wt% of hardwood pulp, adding water into the mixed pulp tank, then entering a refiner, and further performing fibrillation treatment on fibers to enter a pulping tank;
(5) and (4) forming, pressing and drying the pulp from the pulp forming tank in a paper machine.
In the step (1), the addition amount of CMC in the long fiber pulper and the short fiber pulper is 1.0-3.5 kg/t.

In the step (1), the disintegration time is 8-15 minutes.
And (3) the pulping energy consumption of the pulping machine in the step (2) is 90-100 kwh/t.
In the step (2), the gap between every two adjacent teeth of the fluffer is 0.25-2.0 mm.
And (4) the pulping power of the pulping machine in the step (4) is 35-45 kwh/t.
And (4) adding water into the mixed slurry tank in the step (4) to adjust the slurry concentration to 3.0-4.0 wt%.
And (5) diluting the slurry in the slurry forming pool to the concentration of 2.88-3.1 wt%, and pumping to a paper machine.
And diluting the slurry in the slurry forming pool by a fan pump for the second time until the concentration is 0.2-0.25 wt%, and then feeding the slurry into a paper machine.
Compared with the prior art, the invention has the following beneficial effects:
1. the raw materials selected by the invention comprise softwood pulp and hardwood pulp with a certain dosage ratio, and a certain amount of sodium carboxymethyl cellulose (CMC) is added, wherein, the fiber morphological characteristics of softwood fiber (long fiber) and hardwood fiber (short fiber) are different. The softwood fiber is long and thin, the softwood pulp is relatively pure, and the impurities are few, so that the manufactured paper has good flexibility, high folding resistance and good tensile strength; the hardwood fibers are coarse and short, contain more impurities, have relatively low strength, are relatively loose, have strong absorption performance and have high opacity. Therefore, the produced paper has high bulk and high stiffness.
CMC is an anionic cellulose compound with good water solubility, and can promote wood fiber refining, shorten pulping time and improve pulping efficiency by adding the CMC into the pulp; meanwhile, the CMC is an anionic compound, so that the potential in the pulp can be adjusted, the charge of a papermaking water system is improved, the wood fiber dispersion is promoted, and the paper sheet forming is improved; in addition, the CMC can increase the binding force between fibers and improve the retention rate of dry and wet strength agents, thereby improving the dry and wet strength of paper sheets.
2. In the process, softwood pulp is subjected to fiber cutting and fibrillation in a pulp refining pool before long fibers are knocked. The needle-leaved wood fiber is longer, the low-concentration free pulping is carried out by a pulping machine, the cut fiber is taken as the main fiber, and the fiber is cut and devillicate brooming, thereby preparing for obtaining better paper physical property.
The hardwood pulp enters the pulp pond after the short fiber is knocked through controlling the gaps between the teeth of the defibrator before the short fiber is knocked, and the defibering is adopted to defiber the hardwood fibers due to the self characteristics of the hardwood fibers and the short fibers, so that the fibers are dispersed mainly, and the fibers are not damaged too much to ensure the strength of the fibers, thereby obtaining better paper sheet strength.
3. The paper has the advantages that the strength of the paper is divided into longitudinal strength and transverse strength due to the combination of the long fibers and the short fibers, the longitudinal strength is greater than the transverse strength, the paper is relatively breakable in the transverse direction during use, and is difficult to dissolve in the longitudinal direction in the aspect of dispersion, so in order to balance the use experience and the dispersion, the paper aspect ratio is controlled by controlling the pulp-net speed ratio of the paper machine process parameters during paper production, so that the paper aspect ratio is controlled to be between 1.8 and 2.2, and the good strength and the dispersion of the paper are.
4. Compared with the traditional rag product, the product of the invention is convenient to use, can be directly thrown into a closestool for flushing after being wiped, is easy to dissolve and disperse, does not block the closestool and a sewer, can meet the daily use and cleaning requirements of consumers, does not cause garbage pollution, and is convenient, practical and environment-friendly.
5. The wiping paper produced by the invention is 100 percent produced by degradable natural wood fiber, so the wiping paper is easy to degrade and environment-friendly and cannot cause pollution.
6. The wiping paper produced by the invention has small aspect ratio (1.8-2.2), stiff paper, strong paper, thick hand feeling, certain friction force and better dirt wiping capability.
7. The invention executes a transition flow before production, namely, the wet strength agent in the papermaking system is basically eliminated by producing the base paper without humidifying the wet strength agent for 8 hours, thereby meeting the requirement of dispersibility, improving the production efficiency and reducing the waste of water resources.
