Comparative Properties of Soda Pulps from Stalk, Bast, and Core of Malaysian Grown Kenaf
Soda pulping was performed using kenaf stalk, core, and bast as raw materials. It was observed that all these components could yield good paper characteristics when the resulting pulps were beaten to a freeness of 200 to 300 mL. Soda pulp made from the stalk was comparable to the frond from oil palm in sheet properties, but the latter would require higher beating energy to reach similar freenes...
متن کاملChemical characterization of lignin and lipid fractions in kenaf bast fibers used for manufacturing high-quality papers.
The chemical composition of lignin and lipids of bast fibers from kenaf (Hibiscus cannabinus) used for high-quality paper pulp production was studied. Pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) of fibers showed a lignin with a high syringyl/guaiacyl ratio (5.4) and minor amounts of p-hydroxyphenyl units. Simultaneously, sinapyl and coniferyl acetates were also identified, indicat...
متن کاملChemical characterization of lignin and lipid fractions in industrial hemp bast fibers used for manufacturing high-quality paper pulps.
The chemical composition of lignin and lipids of bast fibers from industrial hemp (Cannabis sativa) used for high-quality paper pulp production was studied. Pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) of fibers showed a lignin with a p-hydroxyphenyl:guaiacyl:syringyl unit (H:G:S) molar proportion of 13:53:34 (S/G ratio of 0.64). p-Hydroxycinnamic acids, namely, p-coumaric and feru...
متن کاملEffect of Impregnated Inorganic Nanoparticles on the Properties of the Kenaf Bast Fibers
The objective of this research was to evaluate the properties of the chemically retted kenaf bast fiber impregnated with the inorganic nanoparticles. High quality kenaf bast fibers were obtained from a chemical retting process. An in situ inorganic nanoparticle impregnation (INI) process was used to introduce the CaCO3 nanoparticles into the retted kenaf bast fibers. It was found that some of t...
متن کاملViscoelastic Properties of Kenaf Bast Fiber in Relation to Stem Age
Kenaf (Hibiscus cannabinus L., Malvaceae) is a high-yielding tropical plant traditionally grown for the long, strong bast fibers that develop in the bark layer of the stem. Cultivation spread internationally in the early to mid-twentieth century, but interest waned, particularly in developed counties, as raw materials for cordage and related products shifted from biological to petrochemical sou...
