The microscopic structure and pulping properties of palm fiber were explored. Soda cooking sulfate conducted compared in terms physical strength the obtained pulps. Sulfate pulp showed better performance than soda pulp, as indicated by 23% higher tensile index, 49% tear 36% burst index. To further elevate strength, long fibered (LFP), namely commercial softwood was mixed with at levels from 20%...

Hibiscus cannabinus, Cannabis sativa, and Hibiscus sabdariffa, fast growing productive annual plants, could provide fiber necessary to partially alleviate the world’s fiber deficit. The present study aimed at producing high yield pulp and the best mechanical strength properties with minimum impact on environment by SAS-AQ, and NSSC-AQ pulping processes. A total alkali of 13% (as Na2O), an alkal...

In the present study, hardwood and softwood pulps were characterized by employing Fourier transform infrared photoacoustic spectroscopy (FT-IR-PAS). The pulp samples examined originated from Swedish sulfite and kraft pulp mills, which utilize different cooking processes and modern bleaching technologies. Partial least-squares (PLS) analysis was used to correlate the spectral data obtained with ...

As an alternative raw material for various cellulose derivatives, the current research studied processing of old corrugated container (OCC) in subsequent stages homogenization (soda cooking) and purification (bleaching with hypochlorite). The properties were characterized four different categories including chemical composition or purity, accessibility, reactivity, structural features. Alkali d...

chemical and morphological characterization of different parts of banana plant(musa paradisica) (peduncle, leaf stalk and pseudo stem) were carried out in orderto assess their potentiality for chemical pulp. each portion was tested forextractives, sodium hydroxide solubility, ash, lignin, cellulose and pentosancontents as well as their fiber length and width. these segmented parts werecharacter...

There is an increasing interest in utilizing xylan from hardwood in the food and non-food area. The liberation of xylan from the cell wall matrix of wood is, however, highly restricted by the strong interactions with the lignin network. Xylan stability against alkaline pulping is particularly high in Eucalyptus globulus owing to its peculiar structure containing galactosyl and glucosyl units at...

Abstract Charged groups in pulp have been shown to enhance the tensile strength of paper produced from pulp. Oxygen delignification introduces charged and it is interest determine how should be distributed between cooking oxygen stage with respect mechanical properties. A number unbleached kraft cooked delignified pulps within a wide kappa range were refined, effects refining on morphology prop...
