亚麻纤维的前处理工艺是加工过程中的重要一环，漂白在前处理中赋予了亚麻纤维全新的面孔。通过紫外可见光光谱分析漂白亚麻纤维过程中的残液，以此探讨漂白工艺对亚麻纤维所起的微观作用。“,”Flax fiber the process before the market is to make flax into an indispensable important step, bleaching in the former processing gives the flax fiber new faces. Through the ultraviolet visible light spectrum analysis, infrared spectrum analysis in the process of flax fiber bleaching residual liquid, so as to explore bleaching process on flax fiber on microscopic effect.
