What is toilet paper made of and what material is toilet paper made of

Process flow: raw material crushing - coarse grinding processing - cooking heating - double-disc refiner - vibrating screen - slurry well - slurry pump - rinsing, bleaching - centrifugation.

Sieve - mixing - pulp pump - paper host - rewinding, punching, embossing - paper cutter - packaging - sales.

1. The appropriate ratio of long and short fibers is the premise of CC soft toilet paper, long fiber pulp can give toilet paper enough strength, while short fiber pulp has a greater impact on hand feeling, especially softness.

Second, a good pulping process is the guarantee for the production of soft toilet paper, for the production of toilet paper, because it is based on the pulp of different fiber lengths as raw materials, it is necessary to strictly control the pulping process. Generally speaking, the long fiber pulp must be beaten to give the toilet paper enough strength, and its pulping degree can be controlled at 30 45"SR, while staple fiber or waste paper pulp is mainly used for dredging, supplemented by light cutting, and its pulping degree can be controlled at 20 30"sr。The beating degree of the net slurry is generally controlled at 28.

3. The role of dispersant and softener cannot be ignored, adding appropriate dispersant to the netting slurry can significantly improve the uniformity of the paper and achieve the purpose of improving the softness and feel of the paper. At present, most domestic manufacturers use imported PEO-WF or domestic PEO as dispersants. When using PEO, it is necessary to pay attention to the selection of its molecular weight, preparation method (preparation concentration and dissolution stirring speed), control of the addition amount (generally 1 0 1 5 kg T paper) and the influence of production water quality.

Fourth, the correct wrinkling process is the key to CC high-grade toilet paper, wrinkling is to peel off the paper sheet that is close to the surface of the dryer, and at the same time the paper page is slightly curled and wrinkled.

The raw materials for toilet paper production mainly include wood pulp, straw pulp, waste paper pulp, etc.

<> toilet paper is made of wood, bagasse, bamboo, straw, wheat straw, reeds, waste paper and other materials containing plant fibers. Toilet paper is formed by cutting and crushing the material into pulp, and then undergoing deinking, bleaching and other processes. Toilet paper, mainly for people's daily hygiene, is one of the indispensable paper types for the people.

Mechanical methods are often utilized to wrinkle the paper, thereby increasing the softness of the toilet paper. Toilet paper is characterized by strong water absorption, uniform thickness, no holes, uniform wrinkles, consistent color, and no impurities. Small rolls of double-layer toilet paper should be perforated, with consistent pitch, clear pinholes, easy to tear, and neat.

1. The waste paper enters the hydraulic pulper, and the hydraulic pulper beats and deinks the waste paper, and the pulp after pulping and deinking flows into the pulp pool; The pulp is lifted from the pulp pool into the high-frequency vibrating screen by the pulp pump, and the high-frequency vibrating screen plays the role of screening and separating debris.

2. After screening, it flows into the slurry pool, and then is lifted into the rinsing machine by the slurry pump, which is used to wash the slurry clean and bleach.

3. After bleaching, it will automatically flow into the slurry pool; Then the pulp is lifted into the refiner, after the refining is ground into a fine slurry, it automatically flows into the slurry pool and then is lifted into the sand sinking tray by the slurry pump, the function of the sand sinking tray is to separate the impurities such as sand ash from precipitation, and then make pure slurry, and then lift it into the slurry stabilization box by the sand removal pump, the function of the slurry stabilization box is to reconcile the concentration of the slurry, and then automatically flow into the net trough, and then enter the finished roll paper after the net cage blanket with slurry, and after the drying tank, it enters the finished roll paper.

4. After rolling the paper, it enters the rewinding machine, and the function of rewinding is to play the role of rewinding, punching, and embossing. It is rewound into a small roll from a large roll, and then enters the slitting machine, which plays the role of slitting, the length of different specifications, and then packages it to the finished product.

Process application

Toilet paper can be made in whole or in part from ** fibers. It is possible to study the use of old cartons as raw materials for toilet paper production. The use of this raw material to make toilet paper, paper towels and napkins has been very effective.

In fact, it is ridiculous to use toilet paper with 89% whiteness to wipe hands, absorb liquids or industrial greases. The North American market has embraced the concept.

Another approach is the development of thermomilled mechanical pulp for the production of toilet paper. Currently, due to the rigidity and coarse fibers of thermomechanical pulp, the bonding strength is insufficient, which reduces the strength of the paper and produces dust when wrinkled, post-processed and used. The advent of enzymes may solve this problem by increasing the strength of fiber bonding.

How is toilet paper processed? Divided into different categories, the photographer recorded the whole process.

Production process: the waste paper enters the hydraulic pulper, and the waste paper is pulped and deinked, and then flows into the pulp pool after pulping and deinking;

The pulp pump lifts the pulp from the pulp pool into the high-frequency vibrating screen to screen and separate debris;

After screening, it flows into the slurry pool, and then it is lifted into the rinsing machine by the slurry pump, the slurry is cleaned, and it automatically flows into the slurry pool after bleaching;

After the slurry is lifted into the refiner to grind into fine slurry, it flows into the slurry pool and then is lifted into the sedimentation table by the slurry pump, and the impurities such as sand ash are precipitated and separated, and then made into pure slurry, and then lifted into the slurry stabilization box by the sand removal pump to reconcile the concentration of the slurry, and then automatically flows into the net trough, and then enters the dryer with slurry from the net cage blanket.

Finally, it goes to the finished roll paper. After rolling the paper, it enters the rewinding machine, and the rewinding punches are embossed. It is rewound into small rolls from large rolls, and then enters the slitting machine, where it is cut into different specifications and lengths, and then packaged to finished products.
