摘　　要：通过碱煮法对新疆废弃长绒棉棉秸秆进行脱胶处理来制备棉秆皮纤维。利用扫描电镜显微镜(SEM)、红外光谱法(FTIR)、X射线衍射仪(XRD)和热重分析仪(TGA)分析了棉秆皮纤维的纵向形态、聚集态结构、晶体结构和热学性能。结果表明,棉秆皮经过碱煮工艺处理后,木质素、半纤维素和果胶等物质含量明显下降,棉秆皮纤维长度为68mm,细度为31dtex,断裂强度为19cN/tex。Xinjiang long-staple cotton stalk bark fibers are prepared by chemical alkali method. SEM, FTIR, XRD and TGA are employed to analyze fiber morphology, aggregation structure, crystal structure and thermal properties of cotton stalk bark fibers. The results show that after being chemically processed, the lignin, hemicelluloses and pectin flux content decreases evidently. The length, fineness and tensile strength index is 68 mm, 31 dtex and 19 cN/tex, respectively.
