Refiner mechanical pulp from kenaf for newsprint manufacture.APPLICATION: Kenaf Noun 1. kenaf - fiber from an East Indian plant Hibiscus cannabinus deccan hemp bimli, bimli hemp, Bombay hemp, Hibiscus cannabinus, kanaf, kenaf, Indian hemp, deccan hemp - valuable fiber plant of East Indies now widespread in cultivation refiner mechanical pulp (RMP RMP right mentoposterior (position of the fetus). ) could be used to make newsprint. Supplementing the de-inked pulp (DIP) from old newsprint (ONP) with 20%-30% of bleached kenaf RMP, strength and optical properties of the newsprint will improve significantly. Kenaf (Hibiscus cannabinus) is an annual, nonwood cellulosic plant from Central Africa and India. Kenaf is being promoted as a potential fiber raw material for the pulp and paper industry The global pulp and paper industry is dominated by North American (United States, Canada), northern European (Finland, Sweden) and East Asian countries (such as Japan). Australasia and Latin America also have significant pulp and paper industries. in view of projected fiber supply constraints, particularly in developing countries. The objective of this study was to optimize a process of refiner mechanical pulp (RMP) from kenaf for newsprint production. We produced RMP from whole kenaf (a 65:35 mix of separated core and bark) and whole stems of 25-38 mm length processed with a Sprout-Bauer 300 mm refiner. We refined water-soaked raw material to a targeted CSF Cerebrospinal Fluid (CSF) Analysis Definition Cerebrospinal fluid (CSF) analysis is a laboratory test to examine a sample of the fluid surrounding the brain and spinal cord. of 100-125 mL. Raw material was refined in several passes to simulate commercial refining. We found that the spacing of refiner plates and the number of passes are important parameters in determining the quality of pulp in a 300 mm Sprout-Bauer refiner. Results indicate that kenaf RMP is suitable for newsprint manufacture. View this paper online at http://www.tappi.org/index.asp?pid=29097 Dinesh C. Mohta was, and Dibyendu N.
