Description

Technical Field

[0001] This invention relates to the field of toilet paper processing technology, and in particular to a processing technology for unbleached toilet paper made from virgin pulp. Background Technology

[0002] This invention relates to a processing technology for unbleached toilet paper, and more particularly to a processing technology that improves the quality and production efficiency of toilet paper by adjusting bacterial culture conditions, optimizing the pulping process, selecting appropriate paper forming and packaging processes, adding antibacterial agents, and using shaftless paper machines.

[0003] Currently, the production of toilet paper typically involves steps such as pulp preparation, beating, paper forming, cutting, rewinding, and packaging. However, traditional production processes have some problems. For example, in the pulp preparation process, conventional fiber sources and extraction methods may lead to unstable cellulose quality, affecting subsequent production steps and the performance of toilet paper. In addition, the conditioning and operation methods during the beating process also affect the physical properties of toilet paper, such as tensile strength and softness. Furthermore, the choice of paper forming and packaging processes has a significant impact on the quality and production efficiency of toilet paper, and existing methods often cannot balance production efficiency and product performance.

[0004] More importantly, as a product that comes into direct contact with human skin, the antibacterial properties and comfort of toilet paper are important factors that users care about. However, traditional toilet paper production processes often neglect to optimize these two aspects.

[0005] Therefore, existing toilet paper production processes still need improvement in terms of pulp preparation, beating, papermaking, cutting, rewinding, packaging, antibacterial properties, and comfort. The purpose of this invention is to provide a new processing technology for unbleached toilet paper to solve the above problems. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides a processing technology for unbleached toilet paper made from virgin pulp.

[0007] A processing method for unbleached toilet paper includes the following steps:

[0008] First, select a bacterium that can produce cellulose;

[0009] This bacterium is cultured in a suitable culture medium, and by controlling conditions such as temperature, humidity and light, it is made to multiply rapidly and produce a large amount of cellulose.

[0010] The generated bacterial fibers are collected, washed, and dried using mechanical equipment to obtain pure bacterial fibers.

[0011] These fibers are mixed with water and pulped;

[0012] Then it is made into paper through a paper machine, and after cutting, rewinding and packaging, it finally becomes unbleached toilet paper.

[0013] Furthermore, during bacterial culture, different nutrients are added to alter the physical and chemical properties of cellulose. Adding 0.1-1 gram of calcium sulfate per liter of culture medium will increase the heat resistance of cellulose by 10%-50%.

[0014] Furthermore, the specific steps for collecting bacterial fibers are as follows: First, filter the culture medium using a 0.22-micron microporous membrane; then, separate the bacterial fibers from the culture medium by centrifugation at 5000-10000 rpm or stirring at a frequency of 200-400 times per minute; finally, remove impurities from the culture medium by washing.

[0015] Furthermore, during the pulping process, 1%-10% of a reinforcing agent (such as polyvinyl alcohol) and 0.5%-5% of a softening agent (such as glycerin) will be added as needed to improve the tensile strength of the unbleached toilet paper by 10%-30% and its softness by 10%-50%.

[0016] Furthermore, the paper-making process includes wet papermaking and dry papermaking. In wet papermaking, the thickness of the toilet paper is controlled to be 0.1-0.5 mm and the density to be 0.1-0.5 g / cm³ by adjusting the speed of the paper machine to 10-50 m / min and the pressure to 0.1-0.5 MPa. In dry papermaking, the ideal drying effect is achieved by adjusting the drying temperature to 80-120 degrees Celsius and the time to 10-30 minutes, which can improve production efficiency by 20%-80%.

[0017] Furthermore, during the cutting process, the cutting size of the cutting machine can be adjusted by 10-20 cm and the speed by 100-300 times / minute according to market demand and packaging specifications. During the rewinding process, the speed of the rewinding machine can be adjusted by 10-30 m / min and the pressure by 0.1-0.5 MPa to achieve the ideal winding tightness, such as an inner diameter of 3-5 cm and an outer diameter of 7-10 cm. The packaging process includes manual packaging and automatic packaging. Automatic packaging can increase production efficiency by 50%-200% and reduce labor intensity by 50%-80%. Manual packaging can improve the flexibility and personalization of packaging, such as customizing toilet paper of special sizes and styles according to consumer needs.

[0018] Furthermore, during the bacterial culture process, the culture conditions are adjusted to set the temperature to 30-37 degrees Celsius, the humidity to 60%-90%, the light intensity to 1000-3000 lux, and the pH to 6-8, in order to optimize the bacterial growth environment and increase cellulose yield by 10%-50%.

[0019] Furthermore, during the pulping process, a high-shear stirring method is selected, with a stirring frequency of 200-500 times per minute, to better disperse the fibers in the water, thereby improving the uniformity and softness of the toilet paper by 10%-30%.

[0020] Furthermore, during the pulping process, a certain amount of antibacterial agent, namely silver acetate at 0.1-1 g / L, can be added to improve the antibacterial properties of the toilet paper and increase its safety in use.

[0021] Furthermore, the packaging process will utilize fully biodegradable materials, giving the packaging materials excellent environmental performance.

[0022] The present invention has the following beneficial effects:

[0023] 1. This invention, by adjusting bacterial culture conditions, can significantly improve the quality and stability of cellulose, providing a solid foundation for subsequent production steps and the performance of toilet paper.

[0024] 2. By optimizing the pulping process and adjusting the type and proportion of additives, this invention can significantly improve the tensile strength and softness of toilet paper, providing a better user experience.

[0025] 3. By selecting appropriate paper-making and packaging processes, this invention can effectively improve production efficiency, and by using fully biodegradable packaging materials, it can greatly improve the environmental performance of packaging materials.

[0026] 4. By adding an antibacterial agent, this invention can significantly improve the antibacterial properties of toilet paper and enhance the safety of users when using toilet paper. Attached Figure Description

The packaging process includes manual packaging and automatic packaging. Automatic packaging can increase production efficiency by 50%-200% and reduce labor intensity by 50%-80%. Manual packaging can improve the flexibility and personalization of packaging, such as customizing toilet paper of special sizes and styles according to consumer needs.

[0046] During the pulping process, the antibacterial properties of toilet paper can be improved and the safety of use can be increased by adding a certain amount of antibacterial agent, such as silver acetate at 0.1-1 g / L.

[0047] During the packaging process, fully biodegradable materials will be used, giving the packaging materials excellent environmental performance.
