Production process and quality standard of toilet paper

As people's requirements for health and environmental protection continue to increase, toilet paper, as a personal hygiene product, has received more and more attention in its production process and quality standards. This article will introduce the relevant knowledge of bulk toilet paper from two aspects of toilet paper production process and quality standards.

Toilet paper production process

1. Pulp production: The main raw material of bulk toilet paper is pulp, and pulp production is an important part of toilet paper production. There are three main methods of pulp production: mechanical pulp method, semi-chemical pulp method and chemical pulp method. Among them, the quality of pulp produced by the chemical pulp method is higher, but the cost is also higher; the quality of pulp produced by the semi-chemical pulp method is between the chemical pulp method and the mechanical pulp method; the cost of pulp produced by the mechanical pulp method is lower, but the quality is higher. It is not as good as pulp produced by chemical pulping method and semi-chemical pulping method.
2. Paper manufacturing: The production of toilet paper requires the use of high-quality paper. There are four main methods of paper manufacturing: wet, dry, semi-wet and semi-dry. Wet manufacturing can produce bulk toilet paper with higher paper quality, but the manufacturing cost is higher and the production efficiency is also lower. Dry manufacturing yields are higher, but paper quality is not as good as wet-laid toilet paper. Semi-wet and semi-dry manufacturing is a combination of wet and dry methods that can balance paper quality and production efficiency to a certain extent.
3. Drying and Processing: After paper manufacturing is complete, the paper needs to be dried and processed. Drying allows the moisture in the paper to evaporate, and finishing cuts the paper to size.

Quality standards for toilet paper

1. Thickness: The thickness of bulk toilet paper is one of the important indicators to measure the quality of toilet paper. Under normal circumstances, the thickness of toilet paper should be between 0.2mm-0.4mm.
2. Absorbency: Bulk toilet paper exists to clean and absorb moisture. The water absorption of toilet paper has a crucial impact on its practical value and consumer experience. In the water absorption test of toilet paper, it is usually necessary to record two indicators: time and water absorption.
3. Strength: The strength of bulk toilet paper is another important indicator of its quality. Strength testing mainly evaluates the strength of paper by its tensile and tear strength.
4. Softness: The softness of toilet paper is another indicator of its quality. Softness testing is usually evaluated using two indicators, the hand feel and the bending radius of the paper.
5. Environmental indicators: The production and use of toilet paper have a certain impact on the environment and health. Therefore, the environmental protection index of bulk toilet paper has also become one of the important indicators for evaluating its quality. Environmental indicators usually include the recyclability of paper, the use of chemicals, etc.

To sum up, the production process and quality standards of toilet paper play an important role in the sustainable development and environmental protection of the toilet paper industry. In the future, the production process and quality standards of bulk toilet paper will continue to receive attention and improvement, and will develop in a more environmentally friendly and sustainable direction.

In terms of toilet paper production technology, more environmentally friendly and energy-saving production methods will be adopted to reduce environmental pollution and resource consumption. For example, use bamboo pulp instead of wood pulp to reduce deforestation; improve paper manufacturing process and increase production efficiency. These improvements will reduce the environmental impact while reducing production costs and increasing the competitiveness of toilet paper.

In short, the improvement of bulk toilet paper production process and quality standards will contribute to the sustainable development and environmental protection of the toilet paper industry. With the continuous development of technology and consumer demand, the production process and quality standards of toilet paper will also be continuously innovated and improved to meet market demand and environmental protection requirements.
