The wood paper making production line is a process where raw wood is crushed, purified, and sent to a papermaking machine for forming in the net section, dewatering the wool cloth, drying in the dryer, wrinkling, and then rolled up. After rewinding, cutting, and packaging, it is sold. The entire system is mechanically simple, structurally compact, and operates reliably, and wastewater can be effectively recycled and reused. Discharging water through sedimentation treatment can reduce pollution. Low total investment is suitable for small and medium-sized investors, and the cost of investment can be recovered in the current year.

Wood production of toilet paper process:

The detailed process of wood production of toilet paper can be summarized in the following main steps, each of which contains specific operational and technical points:

Raw material selection and preparation

1. Choose wood:

The main selection of natural forest wood, such as fir, poplar, birch, pine, etc., these woods have different fiber characteristics, suitable for the production of different types of toilet paper.

Wood requires a certain hardness and stability, the diameter is usually more than 8 cm, to ensure the smooth progress of the processing process and the quality of the finished product.

The moisture content of wood should be controlled below 20% to avoid drying deformation or quality problems.

2. Peeling and cutting:

The harvested trees are peeled to remove bark and impurities.

Use a chipper to cut the peeled logs into long pieces of wood, which are easy to handle later.

Second, the pulping process

1. Soaking and cooking:

Put the cut wood chips into the digester, mix with alkaline solution and white liquid, and cook at high temperature. The purpose of this step is to dissolve the lignin and separate out the cellulose fibers.

During cooking, nearly half of the wood dissolves, forming a cellulose slurry.

2. Washing, screening and bleaching:

After cooking, the cellulose fibers are washed to remove residual chemicals and impurities.

Pure cellulose fibers are further separated by screening equipment.

According to the need, the cellulose fiber is bleached to improve the whiteness and appearance quality of the toilet paper.

Three, the papermaking process

1. Molding and dehydration:

The cellulose slurry is evenly sprayed on the mesh surface of the paper machine, and through the extrusion and dehydration process, the fiber forms a wet paper on the mesh.

In this process, the ratio of fibers (such as 3:7 or 4:6 for long and short fibers) is controlled to obtain soft, absorbent and unbreakable toilet paper.

2. Drying and wrinkling:

The wet paper goes into the dryer for high temperature drying (up to 450°C), so that the water gradually evaporates to form the finished paper.

The drying process is accompanied by a crease treatment, which breaks the bond between the fibers by a scraper, making the paper more elastic, thicker, more absorbent and softer.

Fourth, processing and cutting

1. Multi-layer winding:

Several large rolls of paper are put on the machine together and rolled into multiple layers of finished toilet paper (usually three to four layers) to improve the thickness and strength of the paper.

2. Cutting and packaging:

Cut the coiled toilet paper to form a roll or bag that meets the specifications.

Packaging of the cut toilet paper, such as using plastic film or carton packaging, to protect the toilet paper from contamination and damage.

Additional Processing (optional)

Depending on market demand and specific brand requirements, toilet paper may undergo additional treatment, such as adding softener, bleach, fragrance or color printing.

The process of wood production of toilet paper includes raw material selection and preparation, pulping process, papermaking process, processing and cutting, and additional treatment (optional). Each link requires strict control of quality and technical parameters to ensure that the final produced toilet paper is soft, absorbent, non-irritating and easily soluble in water. At the same time, with the improvement of environmental awareness and technological progress, the production process of toilet paper is also constantly optimized and improved.
