Napkin tissue paper is a widely used product in residential and commercial settings. One of the key steps in producing napkin tissue paper is creating the parent roll, which is the initial tissue paper roll before being cut into smaller sizes. The process starts with the creation of paper pulp, followed by sheet formation, drying, and final winding.
The process of making a napkin tissue paper parent roll involves several steps. Here is a simplified overview of the process:
1. Fiber Preparation: The first step is to prepare the fibers that will be used to make the tissue paper. This can involve selecting and mixing various types of fibers, such as virgin pulp or recycled paper, to achieve the desired qualities in the final product.
2. Pulping: The selected fibers are then mixed with water and processed in a pulper, which breaks down the fibers into a slurry.
3. Papermaking: The slurry is then fed onto a the folding size of the final product, where it passes through a series of screens, press rolls, and drying cylinders. These components remove excess water and fibers, forming a continuous sheet of tissue paper.
4. Calendering: The tissue paper is then passed through a set of calender rolls, which smoothens and compresses the sheet, improving its surface finish and thickness uniformity.
5. Reeling: Once the tissue paper is dried and finished, it is wound onto jumbo reels, also known as parent rolls. These parent rolls can be several meters wide and can hold thousands of meters of tissue paper.
6. Quality assurance: The parent rolls undergo quality checks for factors such as thickness, strength, absorbency, and appearance. Any parent rolls that do not meet the desired specifications may be rejected or adjusted.
7. Conversion: The parent rolls are then transported to a converter facility, where they are unwound and fed into machines that cut and fold the tissue paper into individual napkins. This process can also involve some additional steps, such as embossing or printing designs on the napkins.
8. Packaging: Finally, the converted napkins are packaged and prepared for distribution to various markets and consumers.
It's important to note that the actual process can vary depending on the specific manufacturing equipment and techniques used by different tissue paper manufacturers.
