摘　　要：为提高亚麻的品质,对新疆地区不同生长期的亚麻进行取样,经过预处理后分析不同亚麻的成分、力学性能,并进行红外、衍射等测试,从而得出亚麻品质与生长期的关系。实验结果表明:随着亚麻生长时间的延长,水溶物、果胶、半纤维素的含量逐渐下降,木质素和纤维素的含量不断增加;纤维变得越来越粗,长度不断变长。随着亚麻的生长,纤维强度和模量先上升,而后大概在开花后开始下降,因此,开花期后1周为最佳的生长期。Flax fibers with different growing time in Xinjiang were harvested and studied in order to enhance the quality of flax. The component and mechanical properties were analyzed after these flax were pretreated and infrared and X-ray diffraction were also used in comparisons. The relation between quality and growing time was brought out. The results indicated that components of water soluble substance, pectin and hemicellulose reduce with growing time increasing, and the trend of components of lignin and cellulose is contrary to that of the former. Fineness and length of fiber increase with growing time prolonging, while tenacity and modulus ascend firstly and then descend, the turning point is blossom. Therefore, one week after blossom is the optimal growing time.
