The paper and textile industries continuously seek innovative chemical solutions to improve product quality and manufacturing efficiency. Polyethyleneimine (PEI) offers a compelling set of benefits for both sectors, primarily due to its cationic nature and ability to interact with various substrates. In the paper industry, PEI acts as a highly effective retention and drainage aid, as well as a strengthening agent.

When added during the papermaking process, PEI helps to retain fine fibers, fillers, and sizing agents within the paper sheet. This results in improved paper formation, reduced material loss, and enhanced opacity. Furthermore, PEI contributes to increased dry and wet strength of the paper, making it more durable and resistant to tearing and disintegration, especially in moist conditions. Its application in paper manufacturing is key to producing higher-quality paper products.

In the textile industry, PEI serves as a valuable dyeing auxiliary. Its cationic charge allows it to bind effectively with anionic dyes, improving dye uptake and fixation onto textile fibers. This leads to more vibrant colors, better colorfastness, and reduced dye wastage during the washing process. PEI can also be used in textile finishing to impart specific properties such as improved handle or antistatic effects.
