【Abstract】 The microstructure and chemical composition of flax has been tested in this paper by X ray diffraction and chemical composition analysis. The crystallinity and orientation of flax has been depressed by liquefied ammonia finishing, and the effect of crystallinity and orientation of flax on exhaustion is studied. The content of lignin and hemicellulose has been depressed by treating with alkali H 2O 2 and NaOCl, and the effect of content of lignin and bemicellulose of flax on exhaustion in tested. The results show that the exhaustion of flax is in inverse proportion to the crystallinity and raises along with reducing of orientation of the flax, and goes up along with decreasing content of lignin and hemicellulose.更多还原
