| Abstract:In this study, the fiber morphology, physical properties and chemical composition of the bast fibers of six wild vine species, including Byttneria grandifolia Candolle, Sargentodoxa cuneata (Oliver) Rehder & E. H. Wilson, Bauhinia touranensis Gagnepain, Elaeagnus conferta Roxburgh, Vitis heyneana Roemer & Schultes, Dalbergia mimosoides Franchet, were examined and analyzed. The results showed that the fiber lengths of the six vine species were in the range of 0.81~2.09 mm, and the length-to-width ratio of the Bauhinia touranensis Gagnepain fibers was the largest (98.5); the density of the Sargentodoxa cuneata (Oliver) Rehder & E. H. Wilson was the smallest (1.58 g/cm3), the Bauhinia touranensis Gagnepain microfibrillar filament angle was the smallest (6°~9°), and the degree of crystallinity was the highest (88.83%), and the mechanical performance of the Byttneria grandifolia Candolle fibers was the best, with the wet zero-distance tensile index of 45.8 N·m/g, In terms of chemical composition, Sargentodoxa cuneata (Oliver) Rehder & E.H. Wilson had the highest cellulose content (34.83%) and hemicellulose content (19.28%) and the lowest ash content (2.51%).It was speculated that Sagentodoxa cuneata (Oliver) Rehder & E.F.Wilson fibers were more suitable for pulp and paper production and biomass utilization. |
