The paper industry is increasingly focused on sustainability, with the utilization of recycled fibers playing a crucial role. However, recycled fibers often exhibit reduced strength compared to virgin fibers due to repeated processing and hornification. To address this challenge, the integration of specialized chemical additives has become essential. Among these, amphoteric polyacrylamide (AmPAM) stands out as a highly effective dry strength agent.

Amphoteric polyacrylamide, a copolymer of acrylamide and acrylic acids, possesses a unique molecular structure that allows it to improve paper strength through enhanced inter-fiber bonding. This is achieved by increasing the number of hydrogen bonds formed between fiber surfaces, thereby improving the paper's tensile strength, burst strength, ring-crush strength, and stiffness. Research indicates that AmPAM is particularly effective for secondary fibers, where its ability to compensate for fiber degradation is pronounced. When used at appropriate dosages, AmPAM can lead to significant improvements in the breaking length of paper made from recycled corrugated container (OCC) fiber, often outperforming other common strength additives like cationic starch.

Beyond its primary function as a dry strength enhancer, AmPAM offers several ancillary benefits to the papermaking process. Its amphoteric nature allows it to interact effectively with both positively and negatively charged components within the pulp slurry, contributing to improved retention of fine particles and fillers. This not only reduces material loss, leading to cost savings, but also contributes to a cleaner wastewater stream. Furthermore, AmPAM can positively influence the drainage performance of the pulp, potentially reducing energy consumption during the dewatering stages of paper production. This multi-functional capability makes AmPAM a valuable addition to the papermaker's toolkit.
