新規リグノセルロース系循環型材料の創製（第1報）:　繊維のフリーネスとリグノフェノールの種類がリグノフェノールーファイバー複合体のブリネル硬さにおよばす影響

摘要

New recyclable lignocellulosic composites were prepared by combination of fibermolds and lignophenol synthesized by the phase separative system step 2 process. The purpose of this paper was to investigate effects of freeness of fibermolds and kinds of lignophenol on Brinell hardness of lignocellulosic composites. The next things were found out as the result. The rate of sorbed lignophenol became larger as the concentration of lignophenol-aceton solution were higher. The differences of the rate of sorbed lignophenol and Brinell hardness were not seen between lignophenol-fiber composites of freeness 200 and that of freeness 300. Brinell hardness of lignophenol-fiber composites were more than 10 times of that of fibermolds. Brinell hardness of fibermolds were greatly improved by the sorption of lignophenol.%新規循環型材料として開発したリグノフェノーrnルーファイバー複合体のフリーネスとリグノフェrnノールの種類を種々に変えてブリネル硬さ測定試rn験を行い，以下の結論を得た。rn1．リグノフェノールーアセトン溶液の濃度が高rnいときほどリグノフェノール収着率は大きrnかった。
