The increasing global focus on sustainability has led to a significant rise in the use of recycled fibers in paper manufacturing. While this trend offers environmental benefits, it also presents technical challenges, particularly concerning the performance of chemical additives. Cationic Rosin Size has emerged as a highly effective solution for enhancing the quality of paper produced from recycled materials. This article explores why Cationic Rosin Size is a preferred choice for recycled paper applications and where to source this vital chemical.

Challenges in Recycled Papermaking

Recycled pulps often contain a higher proportion of fines and fillers, and can have a greater 'anionic trash' content. Anionic trash refers to negatively charged contaminants that can interfere with the performance of positively charged (cationic) additives. This can lead to poor retention, inefficient sizing, and overall lower paper quality. Traditional sizing agents may struggle to perform optimally in these complex systems.

The Advantage of Cationic Rosin Size for Recycled Fibers

Cationic Rosin Size, with its inherent positive charge, is particularly well-suited for recycled fiber systems. Its cationic nature allows it to effectively bind to the negatively charged fibers and fines, even in the presence of anionic trash. This improved affinity leads to:

  • Better Retention: More of the sizing agent remains on the fiber, ensuring efficient utilization and improved sizing effectiveness.
  • Enhanced Sizing Efficiency: It provides superior water resistance and ink holdout, crucial for the printability and performance of the final paper product.
  • Improved Strength Properties: Studies have shown that cationic sizing agents can contribute positively to the mechanical strength of paper made from recycled pulp.
  • Compatibility with Alum: When used in combination with alum, Cationic Rosin Size demonstrates synergistic effects, further optimizing performance and stabilizing the wet-end chemistry, a common issue in recycled pulp processing.

The optimal use of Cationic Rosin Size in recycled paper often involves careful consideration of addition points and pH control. As a leading paper chemical supplier, we understand these nuances and provide technical support to ensure our clients achieve the best results.
