In this study, corona discharge treatment is applied to cotton fabric at various discharge voltages and time. The dye uptake of treated fabric was increased when the applied voltage and treating time increased. Its effects on surface modification of cotton fabric and its application in finishing are investigated with a range of analytical methods. The results suggest that corona discharge can be successfully applied the finishing of cotton fabric, especially in the green processing of dyeing.

In order to improve the dyeing property of cotton fiber, in this paper, the cotton fabric was modified by 2, 3-epoxpropyl triethyl ammonium chloride (ETEAC). Four reactive dyes were employed to test the dyeing property of modified cotton fabric. The results showed that the dyeing property of cotton fabric was improved greatly. When the concentration of ETEAC was equal to or above 7%, most of the dye-uptake rate of the modified cotton fabric could reach to nearly 100%. And the dyeing rate was very high. These suggested that the cationic groups with three ethyls could attract anion dyes efficiently, though the cationic groups with three ethyls were greater than cationic groups with three methyls. The modified cotton fabric could not be dyed uniformly. Sodium dodecyl sulfate (SDS) was efficient retarder for the modified cotton fabric.

Modification Of The Surface

Surface modification of polyethylene terephthalate (PET) was studied by corona discharge plasma at different exposure times using air as working gas. The modification of the surface properties are characterized, those are morphology and wettability. Corona plasma treatment was found to modify the PET surface in both morphology and wettability. The corona discharge at atmospheric pressure is a heterogeneous with multiple current pulses, which generates an asymmetric pattern of erosion on the PET surface. The corona discharge treatment erodes the surface and therefore modifies the surface morphology. The roughness of the PET surface increases in the impact point of the corona discharge on the PET surface. An increase in the wettability of PET was also observed after corona discharge treatment at atmospheric pressure.
