我们开发了一种纤维提取方法，从玉米秸秆中提取纤维，其机械性能与普通纺织纤维相似。所开发的纤维提取方法可以部分脱木质素，并从玉米秸秆中生产出适合纺织和其他工业应用的纤维。用x射线衍射和扫描电镜对所得纤维的结构进行了研究。从玉米秸秆中提取的天然纤维素纤维的结构和组成与亚麻、红麻等普通韧皮纤维不同。利用Instron拉伸试验机对纤维的拉伸性能进行了研究。本研究发现，玉米秸秆纤维结晶率相对较低，但微纤维角度与普通韧皮纤维相似。玉米秸秆纤维的结构和性能表明，该纤维适合于生产各种纺织产品。
We have developed a fiber extraction method that produces fibers from cornstalks with mechanical properties similar to that of the common textile fibers. The fiber extraction method developed results in partial delignification and produces fibers from cornstalks that are suitable for textile and other industrial applications. The structure of the fibers obtained was investigated using X-ray diffraction and scanning electron microscope. The structure and composition of the natural cellulose fibers obtained from cornstalks are different than that of the common bast fibers such as flax and kenaf. Tensile properties of the fibers were studied using an Instron tensile tester. This study found that cornstalk fibers have relatively lower percent crystallinity but similar microfibrillar angle as that of the common bast fibers. The structure and properties of cornstalk fibers indicate that the fibers are suitable for producing various textile products.
