xylem and bast fiber properties of six iranian hemp population
natural, renewable, biodegradable and low pollution hemp fibers are an alternative to trees xylem and artificial fibers. in this study, xylem and bast fiber properties of six iranian hemp populations including length, width, wall thickness, lumen width and wall index were measured and compared. to this purpose, collected population seeds from different parts of iran were nursed in a controlled ...
متن کاملManufacturing Paper Sheets from Olive Wood by Soda, Sulphite and Kraft Pulping
Paper sheets from Iranian olive tree produced by soda, sulphite and kraft pulping.Then the influence of pulp beating on properties of paper sheets was studied. Kraft pulp exhibited the highest holocellulose/yield -cellulose/yield ratios and the sulphite pulp the soda pulp the highest lignin/yield ratio. Paper sheets from kraft with the breaking length 5851 m, stretch 4.61%, Burst index 4.48 KN/...
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 کاملStudying Secondary Growth and Bast Fiber Development: The Hemp Hypocotyl Peeks behind the Wall
Cannabis sativa L. is an annual herbaceous crop grown for the production of long extraxylary fibers, the bast fibers, rich in cellulose and used both in the textile and biocomposite sectors. Despite being herbaceous, hemp undergoes secondary growth and this is well exemplified by the hypocotyl. The hypocotyl was already shown to be a suitable model to study secondary growth in other herbaceous ...
