Technology of Glow Discharge Plasma to Improve Color Intensity on Polyester Fabric

The surface modification have been studied onto polyester fiber toimprove color intensity of the dyed fabrics. The modifications carried byetching using glow discharge plasma under condition of 0.04 Torr, using 10Watt at 13.56 MHz. Both surface of original and modified fibers were analyzedby means of scanning electron microscope (SEM), and then both of fibers weredyed with disperse dyes and measured using color measurement apparatus tocompare the color shading, color intensity, and the brightness of the fibers.The color shading of modified fibers have small difference of original fiber,and the color intensity of modified fibers have much higher than originalfibers, while the brightness of the modified fibers tend to decrease. By themeasurements, can be concluded that the surface modifications by glowdischarge plasma are able to improve color deepness of the fabrics, and haveanother advantageous to the character of fabrics.
