摘　　要：利用无声放电方法对聚酯（ＰＥＴ）纤维表面进行接枝改性，为改善聚酯织物的染色性能提供了一条新途径． 傅里叶红外光谱（ＦＴＩＲ）和Ｘ射线光电子能谱（ＸＰＳ）表明，ＰＥＴ纤维经无声放电引发气相接枝丙烯酸改性后，表面的羰基、羟基和羧基等极性基团增加，氧碳摩尔分数比增大． 扫描电镜（ＳＥＭ）观察发现纤维表面粗糙度随放电时间增加而增大． 改性后的涤纶对碱性染料的上染率有所提高．Plasma\|grafting modification of poly (ethylene terephthalate) fibers (PET) surface by silent discharge has provided a novel method of improving dyeing properties of polyester fabrics. FTIR spectrum and XPS spectra indicate that polar groups in the modified PET fibers such as -C=O, -OH and -COO-, as well as the ratio of O/C increase. SEM image shows that the roughness of PET surface increases with increasing discharge time. The dyeability of modified terylene with basic dyes is improved greatly.
