Nine groups of knitted woolen fabrics for sportswear with different technical characteristics were treated with oxygen low-temperature plasma, and the changes in the surface morphology and chemical composition of wool fibers before and after plasma treatment, as well as the changes in the applicability indexes of knitted woolen fabrics, were studied. Finally, the comfort performance of the fabrics was evaluated by combining the concentration mapping method and the function evaluation value method. The analysis found that the surface scales of wool fibers were seriously etched after oxygen low-temperature plasma treatment, and the anti-felting, bursting strength and moisture absorption of the knitted woolen fabrics were improved. At the same time, the quick-drying index of the fabric has also been improved to a certain extent. This research provides a basis for the development of knitted woolen fabric for sportswear with excellent performance.

This paper discussed the influences of plasma processing time and power on wool fibers, the results showed that: after plasma treatment, the surface of the wool fibers occurred varying degrees of physical and chemical etching phenomenon, the wetting property was increased significantly, anti-shrinkage performance was improved. Breaking strength and elongation at fracture were increased; the beginning of dyeing properties and the balance rate were increased.

With the increase in the environmental protection consciousness of people, attention has focused on plasma technology because of its efficiency and environmentally friendliness. In order to improve the dyeing behavior of wool fabrics, surface modification of wool fabrics was carried out using an atmospheric pressure (argon) low temperature plasma treatment (LTP). Morphology and chemical composition analyses of the treated wool fiber surface were carried out by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The effect on the surface properties of wool fabrics treated for different times was evaluated. The results showed that the coloration of wool fabric is improved with an argon atmospheric pressure low temperature plasma (LTP) treatment but the fabric has a lower color fastness to washing and rubbing. This results from the formation of sulfonic groups and the increase in nitrogen content attributed to more severe etching and oxidization on the surface of wool fibers.
