测定了剑麻纤维改性前后的结晶度和抗拉性能．结果表明，经１５０℃或１８０℃热处理后，剑麻纤维的结晶度和拉伸性能都有所提高．经浓的氢氧化钠和醋酸处理后，剑麻纤维的断裂伸长率增加而拉伸模量下降
The crystallinity and tensile properties of sisal fiber before and after modification were measured. The results showed that the crystallinity and tensile properties of sisal fiber increased after heat treatment at 150 ℃ or 180 ℃. After concentrated sodium hydroxide and acetic acid treatment, sisal fiber elongation at break increases tensile modulus decreased
