Abstract
Synthetic fibers have gained its popularity and constitute a big share of market in textile industry. Due to their hydrophobicity and resistance to chemicals, these fabrics require pre-treatment prior to finishes such as printing. Without having them pre-treated the patterns directly printed with pigment paste have poor color yields and bleed easily. Plasma surface treatment of POP, PES fabrics was carried out in atmospheric plasma with air under different time intervals. After the samples were exposed to plasma were printed with pigment paste. Affectivity of the modification process was determined with hydrophilicity measurements evaluated by means of suction test. Hydrophilicity of individual fabrics has distinct increase after plasma treatment. From the results obtained it can be seen that surface ?modified POP, PES fabrics registered enhanced color yields and remarkable good pattern sharpness. XPS and SEM analysis showed that this tremendous improved color performance was assisted by the polar groups induced onto the fiber surface through plasma processing. SEM images exhibited that the rough surface of plasma treated fibers could give more potential for fabric to seize the printing paste .Therefore surface modification using air plasma provides a possibility to process fabric for pigment printing ,which is also advantageous in that ,it is environmentally friendly ,saving energy compared to the traditional pre-processing methods.
