Özet

AKD (Alkyl Ketene Dimer) has most spread using an internal sizing agent in the world, not only high efficiency to improve strength properties but also environmentally friendly agent. AKD production is greatly increased year by year and at the same time the price of AKD is decreasing. Previous studies applied AKD-Heptane solution with dipping method Seo et al. [1-4] for full hydrophobicity of paper samples. Also, printing method used by other researcher with ink jet printer for obtain patterned paper surface Kannangara et al. [5-7] Similar method used by W Shen and Liyun Guan as they dipped to the filter paper to Heptane-AKD solution Shen et al. [2]; Guan et al. [8]. From this model study, it could be suggested that AKD or hydrolyzed AKD attached and oriented on the cellulose surface by formation of the hydrogen bonding and ester bonding at the blending and heating stage, respectively Odberg, et al. [9]. Comparing these two commonly used methods it will offer an alternative option for situations where the paper need a certain degree of resistance rather than fully resistant to water.
