The Structure and Properties of the Degummed Kosteletzkya virginica Bast Fiber

Abstract:

In this paper, the bast fibers of the Kosteletzkya virginica were degummed and separated into fine fibers, the chemical composition, morphology, microstructure and mechanical properties of the degummed Kosteletzkya virginica bast fibers were characterized by means of SEM, ART-FTIR, DSC-TGA, XRD and Instron tensile tester. The results showed that the surface of the Kosteletzkya virginica bast fibers was smooth, and there were many visible grooves along the vertical section. Typical celluloseⅠin the Kosteletzkya virginica bast fibers was confirmed by FTIR and XRD analysis.The crystallinity of the Kosteletzkya virginica bast fibers was higher than the cotton fibers and lower than the castor-oil plant bast fibers. The beginning and maximum decomposition temperature of the Kosteletzkya virginica bast fibers were 252 and 347 °C respectively, which indicated that the Kosteletzkya virginica bast fibers had an appropriate thermal stability. The Kosteletzkya virginica bast fibers had a better mechanical properties and excellent hygroscopicity. All the results showed that the Kosteletzkya virginica bast fiber was one of an ideal candidate for the new textile material.
