摘要:

为提升苎麻纤维的柔软性,采用N-甲基吡咯烷酮(NMP)对其进行处理。探讨不同NMP质量分数、处理时间和温度对苎麻纤维强伸性能和柔软性能的影响,并借助X射线衍射仪、红外光谱仪和扫描电子显微镜对苎麻纤维进行表征与分析。结果表明:当NMP质量分数、处理时间或温度任一因素增加,苎麻纤维的断裂伸长率随之增加,而断裂强度随之降低;当NMP质量分数或处理时间增加时,苎麻纤维的断裂回转数会先增加后减少,当处理温度升高时,断裂回转数会先增加后保持稳定;在NMP质量分数为15%,处理时间为60 min,处理温度为80 ℃的较佳工艺条件下,处理后苎麻纤维的结晶度从80.37%降至70.19%,而其化学基团保持不变,纤维表面纵向沿竖纹出现劈裂。

Abstract:

In order to improve the softness of ramie fibers, N-methyl-2-pyrrolidone(NMP)was used to treat them. The effects of NMP mass fraction, time and temperature on the mechanical properties and softness of ramie fibers were studied. Meanwhile, the ramie fibers were characterized by X-ray diffractometer, infrared spectrometer and scanning electron microscope. Results show that when the NMP mass fraction, treatment time or temperature increases, the elongation of ramie fibers increases, and the tensile strength decreases. When the NMP mass fraction or the time increases, the twisting number of ramie fiber increases first and then decreases. When temperature increases, the twisting number increases quickly and then keeps stable. The optimum treatment conditions are NMP mass fraction of 15%, time of 60 min and temperature of 80 ℃, the crystallinity of treated ramie fibers decreases from 80.37% to 70.19%, but the chemical groups remain unchanged, and cracks appear along the vertical lines on the surface of ramie fibers.

Key words: ramie fiber, N-methyl-2-pyrrolidone, softness treatment, softness, crystallinity
