Tissue paper is produced on a paper machine that has a single large steam heated drying cylinder fitted with a hot air hood. The yankee cylinder is sprayed with adhesives to make the paper stick.
The processes are not so obvious to the end-user but contribute immensely to the overall quality of the product on how easily the paper releases, how well the paperboard core stays in tack, and how well the roll keeps its shape.
Release Aid works as a defoaming agent in pulp washing system. It is a water based defoamer and can be easily diluted on line and offline. It helps in improving the productivity of wash plant. It has been specially formulated to take care of downstream problems of pitch etc.
Tissue softness is enabled by selection of proper pulp, improvement of beating process or addition of chemical agents during papermaking. Among these methods, addition of chemical agents is the most common way to improve the softness of tissues.
Wet Strength Resins
The wet strength of paper and paperboard is a measure of how well the web of fibers holding the paper together can resist a force of rupture when the paper is wet. Wet strength is routinely expressed as the ratio of wet to dry tensile force at break.
These agents are commonly used in the process of imparting fine and uniform ridges in household paper products such as tissue / toilet paper. They help smooth the surface of paper that gives the paper a more pleasant and comfortable feel.
Water-Soluble Resins are used as thickeners, binders, and association compounds in paints, coatings, paint removers, cements, and concrete. Water-Soluble Resins provide aqueous thickening to provide proper body and application properties.
Reduction in refining energy. Reduction in Refining time or Amperage leading to a reduction in electrical costs. Helps to reduce build-up of fines in forming and press fabrics, increasing fabric life. Improvement in wastewater quality.
