Tissue paper has been an important part of the papermaking industry for many years. Today, the continuous growth in the production capacity of colored tissue paper is achieved through new technologies that meet the quality of the product. The development of multi-layer pulp box provides the opportunity to use different primary fibers and secondary fibers at the same time in the production of sheet paper and makes the final products multi-functional. In a multi-layer head box, a single layer of paper is usually formed by a combination of two ingredients or three layers of fiber. Tissue paper is produced on a paper machine that has a single large steam heated drying cylinder (yankee dryer) fitted with a hot air hood. The raw material is paper pulp. The yankee cylinder is sprayed with adhesives to make the paper stick. Creping is done by the yankee's doctor blade that is scraping the dry paper off the cylinder surface. The crinkle (creping) is controlled by the strength of the adhesive, geometry of the doctor blade, speed difference between the yankee and final section of the paper machine and paper pulp characteristics.
In addition to the use of multi-layer head box, concentration dilution distribution technology can reduce the quantitative change of paper pages. This technology can easily be used after modification of the existing paper machine. Especially for multiple layers. The quantitative distribution can be reduced from 2.0% to 1% by using the concentration dilution and distribution technique in the head box. Reduce the quantitative fluctuations of the page and produce a uniform sheet of paper.
Crepe paper sheets
Tissue paper is a lightweight paper or, light crepe paper. Tissue can be made both from virgin and recycled paper pulp.
Key properties are: strength, absorbency, basis weight, thickness (bulk), brightness, stretch, appearance and comfort.
