Based on the 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 X-ray photoelectron spectroscopy (XPS) indicated that the moisture can increase the etching effect of 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 beta sheet, alpha helix and random coil conformation. X-ray Diffraction (XRD) confirmed that the JPAP and the moisture had little effect on the crystallization of wool. Therefore, JPAP treatment will be beneficial to the processing of high moisture fiber. Source

By means of scanning electron microscope (SEM), atomic force scanning probe microscope (AFM) and fiber friction coefficient tester (FFT), this paper investigated the influences of moisture on the surface morphology, surface roughness, directional friction effect (DFE) and felting shrinkage of knitted wool fabric during the jet plasma at atmospheric pressure (JPAP) treatment. The result showed that the moisture will be beneficial to the surface modification of wool in different degree. Especially the wet JPAP processing, with significantly etching effect on scales, obviously static and dynamic directional friction effect, and relatively few surface roughness, can basically achieve the machine washable standard with felting shrinkage less than 8%.
