| 摘 要： | 通过实验表征了国产木棉纤维的基本结构和性能。木棉纤维壁薄,具有高达97%的中空率,壁厚不均匀,纵向表面有微小凸痕。纤维头端逐渐变细,尾端较粗,呈自然紧闭状态。所测木棉单纤维密度达0.30gcm3,主要由纤维素和木质素组成,结晶度为35.9%,双折射率为0.017,其胞壁结构较棉纤维疏松。木棉纤维具有优异的耐热性能,分解温度为296℃,在354℃时木棉纤维基本停止分解,发生炭化。

| Abstract: | The structures and performances of the native kapok fibers were studied.The kapok fiber has thin wall and huge lumen,the hollow ratio can reach 97%.One end of the fiber tapers to one point and is closed,and the other end is bulbous shape and may be closed tightly.The bulk density of the fiber is 0^30 g/cm3.The kapok fiber mainly consists of cellulose and lignin,the crystallization degree is 35^90% and the specific birefringence is 0^017.The structure of the cell wall is looser than that of cotton.The fiber is good heat-resistant,which decomposing temperature is 296 ℃. The fiber stops decomposing and happens carbonizing at 354 ℃. |
