摘　　要：对蓆草、棕丝草、琅琊草、咸草、蒲草等5种帽用草纤维用扫描电镜观察其表面形态和截面结构,发现帽用纤维表面存在大量的气孔和沟槽,测量出气孔的长度20-73μm,宽度8-33μm。截面有较大的空隙,纤维空隙的大小依次是棕丝草、蒲草、琅琊草、蓆草、咸草。对其表面选取微区进行EDS能谱分析,结果表明5种帽用草纤维都含有C、O、Al,且C、O元素的含量都在96.99%以上,其他如Si、Na、Mg、Cl、P等属于微量元素,属纤维素纤维。Surface morphology and cross-section structure of 5 types of grass fibers for caps（mat grass,harness wire grass,yellow grass,salt grass and cattail grass）were observed with SEM.It is found that there are large quantities of pores and grooves on the surface of fibers used to make caps.The length of those pores ranges from 20 to 73μm,while the width ranges from 8to 33μm.The ratio of length to width is 2to 3.There is large space on the cross-section,and the sequence of fiber space is as follows：harness wire grass,cattail grass,yellow grass,mat grass and salt grass.EDS energy spectrum analysis is conducted for the micro-area on the surface.The results show all those fibers contain C,O,Al,and the content of C and O is above 96.99%.Other elements such as Si,Na,Mg,Cl and P belong to microelements.So those fibers are cellulose fibers and belong to cellulosic fiber.
