SURFACE CHARACTERISTICS AND SIZING RESPONSE OF PAPER SHEETS SIZED BY ANIONIC EMULSION OF FATTY ACIDS

摘要

The surface characteristics of paper sheets tub-sized with emulsion size were investigated for the mechanism of sizing response by X-ray photoelectron spectroscopy and pyrolysis gas chromatography. The atomic ratio of carbon, indicating the surface abundance of hydrophobic size components on paper sheets, reflected well the sizing response that was not attributed to the size content. The aluminum components on the fiber surfaces must behave as an inhibitor for the self-assembling of the size components themselves, and contribute to the sizing enhancement.
