Abstract

Aging of plasma surface modification of inkjet printing polyester fabric was investigated. Woven polyester fabrics were exposed to atmospheric pressure air plasma and then stored at the standard condition of 20°C and 65% relative humidity to perform the aging experiments. The surface morphology and chemical compositions of the control and treated samples were analysed by scanning electron microscopy and X-ray photoelectron spectroscopy. Wetting time was used to evaluate the surface hydrophilicity on each sample. The aging effect could be detected only in the surface chemical compositions, whereas the morphology remained stable for 45 days. Research on the antibleeding property and colour strength showed that the inkjet printing property of polyester fabrics decreased with increasing aging time until a plateau value was reached. The modified fabrics should be printed within 24 h after plasma treatment in order to get fresher colour and better antibleeding performance.
