摘　　要：在优化工艺的基础上,研究了3种湿度环境对常压射流等离子体(JPAP)处理亲水性羊毛的表面形貌、表面元素含量、结晶度与构象的影响。通过Allwrden反应和X射线光电子能谱(XPS),认为水分能增加JPAP对羊毛纤维鳞片表皮的刻蚀作用,也会改变JPAP处理羊毛表面的C、O、N、S以及特征官能团的含量。通过Peakfit软件分析衰减全反射红外光谱(FTIR-ATR),认为水分基本不影响JPAP处理羊毛分子的构象或蛋白质二级结构,但对β-折叠、α-螺旋和无规卷曲等构象含量略有作用。通过X射线衍射(XRD),认为JPAP处理以及水分的存在对羊毛结晶度影响不大。因此,JPAP处理有利于加工高湿羊毛纤维。Based on optimization process, this paper investigated the influences of jet plasma at atmospheric pressure （JPAP） on the epidermal morphology, surface element content, crystallization and conformation of hydrophilic wool fiber. AllwOrden reaction and photoelectron spectroscopy （XPS） indicated that the moisture can increase the etching effect of X-ray JPAP on the scale epidermis of wool fiber, and also changed the content of C, O, N, S and the characteristics of functional group. FTIR-ATR analyzed by Peakfit software illustrated that the moisture did not impact the molecules conformation or protein secondary structure, except a little for ta sheet, alpha helix and random coil conformation. X-ray Diffraction （XRD） confirmed that the AP and the moisture had little effect on the crystallization of wool. Therefore, JPAP treatment will beneficial to the processing of high moisture fiber.
