| Abstract | This study examined the beating responses of some Chinese non-wood fibers (including unbleached species of wheat straw, bamboo, bagasse and reed pulps, as well as bleached bamboo pulp, while using the bleached/unbleached Eucalyptus pulps as references) in order to understand some of their basic quality profiles from a technological perspective, and papermaking potential. Non-wood pulps were subjected to PFI mill refining after which paper sheets were made by white water recirculation sheet-molding system, and Schopper Riegler (SR) number and water retention value (WRV) were measured as drainability responses, meanwhile the beating behaviors of paper properties were demonstrated through the development of strength and optical properties as well as other characteristics. The responses of SR and WRV to PFI beating showed that agro-residual fibers, Bagasse pulp especially Wheat straw pulp, respond to refining more easily than Bamboo pulps and annual grass – Reed, furthermore, bleached species were more difficult to beat than unbleached ones in this regard. The corresponding paper properties after beating displayed superior strength and optical properties of bamboo pulps over other nonwood pulps even Eucalyptus pulp, while wheat straw pulp and reed pulp demonstrated a higher opacity and better smoothness, and bagasse pulp is excellent in forming dense and smooth paper though still keeping a relatively higher brightness than other non-wood pulps. These results indicate a strong competence of non-wood pulps to substitute some grades of wood pulps in existing mills, and great potential of adding non-wood pulps both as the main furnishes or as supplementary furnishes to upgrade or develop new grades of papers, since the above inherent superiorities of each pulp type over others’ may be preferable when applied in various paper & board grades, such as printing & writing papers, tissue, packing & wrapping, liner board and corrugated medium. |
