Abstract
Through quantitative analysis of chemical composition of the French flax,the components of flax were gained respectively:lipid-wax 1.06%,water soluble substance 2.96%,pectin 3.45%,semicellulose 19%,cellulose 66.6%,lignin 4.22%,ash 0.68%. Compared with domestic flax fiber,it is found that pectin,semicellulose and cellulose content of France flax fiberare higher than those of domestic flax fiber,while lipid-wax, water soluble substance and lignin content are lower than those of domestic flax fiber.Ash content is similar.The microstructure and super molecular structure form of the French flax fiber were determined by scanning electron microscopy(SEM),and X-ray diffraction(XRD) analysis methods.The results show that the internal molecular structure of the France flax fiber is very tight,the fibre macromolecules in the crystalline region are arranged neatly.Its original molecular orientation and crystallinity are a little higher than those of domestic flax fiber.This research provides basis for formulating green and environment-friendly degumming scheme.关键词
