製紙特性に関連するイネワラのホロパルプ構成要素

摘要

The characteristics of holopulp elements from rice straw were studied to obtain fundamental knowledge related to their papermaking properties. Various methods to prepare rice straw holopulp were examined, and the chlorite-sodium hydroxide method was found to be most suitable. In this method the sodium hydroxide treatment was very effective for defibration and desilication. The classification of holopulp to separate the fiber elements from the non-fiber elements was achieved successfully. Although rice straw contains a considerable amount of fines elements, the fiber elements have much higher slenderness ratio and are slightly shorter than those of hardwood fibers
