Development of High Quality Printing Paper Using Kenaf Fibers: Kenaf (Hibiscus Cannabinus), an Alternate Fiber for the Pulp and Paper Industries in Developing Countries Alireza Ashori

Kenaf (Hibiscus cannabinus)is an annual non-wood plant which has shown great potential as an alternative source of papermaking fiber. The purpose of this research was to investigate the suitability of Malaysian cultivated kenaf fibers in the production of high quality printing paper. The first part of the research characterized the chemical, morphological and pulping properties of different fractions (bast, core and whole stem) of kenaf. The second part of the research investigated the production of bleached pulp using environmentally-friendly method, TCF. Conventional Elemental Chlorine Free (ECF) bleaching sequences were also used to compare the results with the TCF sequences. The third part of the research studied the polymer deposition, surface topography and printability. The overall conclusion is that whole stem kenaf is an attractive raw material that is suitable for use in the production of high quality printing paper in areas where forest resources are inadequate. Chitosan is recommended as an additive in conventional surface sizing to enhance strength and surface properties.
