Abstract

Octadecylamine is effective as an internal sizing agent when used alone, or without alum as a mordant. With unbleached kraft, pulp, 0.25% octadecylamine (on dry pulp) was enough to induce sizing. Bleached kraft pulp required 0.5% octadecylamine. The sizing efficiency depended onthe temperature, the presence of metallic, ions, and the storage timeof the stock. The optimum pH range was 7-10. paper strength decreasedwith the use of octadecylamine. However, cationic starch can be addedto overcome the strength loss.
