Improvement of Wool Surface Characteristics by Using the Atmospheric Pressure Glow Discharge

This study investigates the enhancement of wool fabric properties using atmospheric pressure glow discharge (APGD) plasma. The wool samples are exposed to APGD plasma under different conditions of the current and treatment time. It achieved significant improvements in the wettability (wetting time reduced from 332.4 s to 93.6 s), felting shrinkage (from 6.4% to 3.93%) and the whiteness improved significantly. The plasma treatment cleans the wool surface and enhances dye uptake, offering a sustainable approach for textile processing. The treated samples were examined by scanning electron microscope Scanning Electron Microscopy (SEM) and FTIR spectroscopy that confirm the changes in its surface morphology the formation of new functional groups on the wool fabric.
