摘要
藕丝是一种天然纤维,扫描电镜显示其外型具有与藕的外型相同的节状特征,其单丝直径在微米尺寸范围内,平均强度约为1.3 cN,最大延伸率约为1.1%。DSC分析发现藕丝的玻璃化转变温度在43℃左右,而红外光谱则显示藕纤维主要含多糖物质。
Lotus root is natural fiber and SEM analysis showed that this natural fiber has similar morphologic aspect, e.g. nodulated, as its bulk and the diameter of single fiber is to be in the range of micrometer. The average breaking intensity of single fiber is about 1.3 cN with an elongation of about 1.1%. DSC result indicated that lotus root fiber has a glass transform temperature at about 43℃, and FTIR spectrum showed this natural fiber is rich in polysaccharides.
